Abstract (sommario):

To improve the ability of the fuzzy edge detection and anti-noise performance, the paper proposes a new weighted direction fuzzy entropy image edge detection method. The proposed method converts the feature space of image gray to the fuzzy feature space, and then extracts the weighted information measure of the direction structural in the fuzzy entropy feature space. Finally, the proposed method determines the edge pixel by an adaptive threshold after non-maxima suppression. The experiment demonstrates that the proposed method can extract the image edges effectively by means of the fuzzy edge detection.

Abstract (sommario):

In this paper we will show a way how to detect edges in digital images. Edge detection is a fundamental part of many algorithms, both in image processing and in video processing. Therefore it is important that the algorithm is efficient and, if possible, fast to carry out. The fuzzy set theory based approach on edge detection is good for use when we need to make some kind of image segmentation, or when there is a need for edge classification (primary, secondary, ...). One example that motivated us is region labeling; this is a process by which the digital image is divided in units and each unit is given a unique label (sky, house, grass, ?, etc.). To accomplish that, we need to have an intelligent system that will precisely determine the edges of the region. In this paper we will describe tools from image processing and fuzzy logic that we use for edge detection as well as the proposed algorithm.

Abstract (sommario):

In image processing, edge detection is a critical issue. Edge detection is a key approach for evaluating the edge of various objects in a digital image. These edges are found using the gradients, which are present in the image. The intensity and value of pixels determine the gradients. In digital images, edge detection lowers the quantity of data and filters out irrelevant data while maintaining the image's key structural features. In this paper, a new edge detection approach based on a fuzzy rule-based system is proposed. In digital image processing, the proposed method typically depends on fuzzy logic systems. The main goal of this system is to show how fuzzy logic may be used in image processing. This paper provides a fuzzy logic-based edge detection technique that uses a sharpening Gabor filter to regulate edge quality and a Gaussian filter to reduce noise caused by sharpening. This is determined by utilizing applications such as “Peak Signal to Noise Ratio (PSNR) F-Measure, and Hausdorff distance (HoD) to prove that fuzzy logic outperforms the proposed system. The findings for edge detection approaches are included in high quality. The proposed approach outperforms most commonly used traditional edge detection methods. The proposed method also reduces the number of noisy features and may be used for a wide range of images.

Abstract (sommario):

This paper presents a hybridization of Particle Swarm Optimization (PSO) and Fuzzy edge detector. The edge detector is used as the initial population and as the objective function. The purpose of hybridizing the algorithm is to create an optimized edge detector. Classical Fuzzy Heuristics (CFH) detects thick edges. These thick edges need to be optimized to obtain a thin line. In this research the PSO is used to optimize the edge detection detected by the CFH algorithm and it is referred to as FHPSO. The test images are radiographs images of the metacarpal. These images have been used, because there is a need to detect strong and thin edges. Radiograph images are noisy in nature, which makes it difficult to measure the cortical thickness, the cortical outline of the inner cortical and outer cortical of the long tubular bone. The outer cortical edges are considered to be the strong edges due to high discontinuity values and the inner cortical edges are considered weak edges due to low their discontinuity values. The performance of FHPSO in detecting edges has been shown to be quite efficient.

Abstract (sommario):

In this paper a method has been developed for automatic edge detection of an digital image. An edge is made up of those pixels at which there is an abrupt change in the intensity. These pixels are known as edge pixels and are connected to give an edge. In this paper we have developed a mamdanis fuzzy inference system in MATLAB 2008 using fuzzy logic tool box. A smallest possible 2X2 window is used as a scanning mask. Mask slides over the whole image pixel by pixel, first horizontally in topmost horizontal line then after reaching at the end of line, it increments to check the next vertical location and it continues till the whole image is scanned. The FIS built has 4 inputs, each input representing a pixel for 2X2 mask, and 1 output that represents pixel under consideration. The rule editor consists of sixteen fuzzy rules. The results thus obtained are compared with Sobel edge operator and Canny edge operator.

This work has developed a new method for digital image contour detection which can be successfully applied to images presenting objects of interest with high proximity and presenting complexities related with background abrupt intensity fluctuations. The developed method makes use of fuzzy logic and declivity standard deviation (Fuzzy Declivity Standard Deviation FuzDec) to image processing and contour detection. Contour detection is an important task to estimate two-phase flow features through bubble segmentation in order to obtain parameters as void fraction and bubble diameter. FuzDec was applied to natural circulation instability images which were experimentally acquired. Image acquisition was done at the Natural Circulation Circuit (CCN) of the Instituto de Pesquisas Energéticas e Nucleares (IPEN) in Brazil. This facility is all made up with glass tubes allowing easy visualization and imaging of one-phase and two-phase flow patterns during natural circulation cycles under low pressures. Results confirm that the proposed detector can improve contour identification when compared to classical contour detector algorithms, without using smoothing algorithms or human intervention.

Abstract (sommario):

Images are one of the best sources for research & communication. Proper analysis of image data is essential for various fields like satellite images & remote sensing, Biometrics, Criminology, military surveillance, astrology & many more. Requirements of the users vary according to the nature of application in use.Image processing plays a critical role in the analysis of data and is an integral part for various applications. Image denoising is one of the challenging branches of image processing. Impulse noise is among the prevalent noises that degrade the image quality and its subsequent noise suppression plays a pivotal role in the enhancement of images. The presence of impulse noise cannot be averted during the digitization, acquisition, and transmission of images. Many state of art filters are available in the literature to deal with impulse noise encountered in images. Filters having dual modes of detection and restoration exhibit superior performance in removing noise and thereby keeping the original information of the images intact. In real world sometimes the user is uncertain about his requirements therefore the characteristics of the employed filter for impulse noise removal should be adaptable to the indecisive features of an image.The denoising filter should be robust enough to handle the varying amounts of noise density and should be intuitive in nature. This thesis work tries to cater to all the essential features required for an efficient filter. Incorporation of fuzzy logic makes the filter more versatile.Investigations performed in this thesis show that the proposed work excels in the quantitative as well as qualitative manner. Four schemes introduced in this thesis are : (i) High-density impulse noise detection using FCM algorithm (HDIND) viii (ii) Edge preserving fuzzy filter for the suppression of impulse noise in images (EFFSIN) (iii) Heuristic analysis of neighboring pixels for impulse noise detection (SPHN) (iv) Impulse noise removal in color image sequences using Fuzzy logic (INFL) The initial three schemes namely HDIND, EFFSIN, and SPHN focus on the grayscale images and INFL is proposed for color image sequences. All the schemes incorporate an efficient detection criterion and after proper classification of noisy and noise-free pixels, performs the restoration procedure. The use of fuzzy logic in the methods has enhanced the decision making aspect of the algorithms to classify the noisy pixels present in an image. The simulation results are done in isolation for all the schemes deduce that HDIND and EFFSIN are robust in nature and their performance does not deteriorates with a rise in noise density. The edge-preserving nature of EFFSIN preserves the original image data and false alarm rates are reduced. SPHN provides good PSNR and MSE results. INFL is a Spatio-temporal filter that gives excellent performance. SSIM, PSNR, MSE, False alarm and Miss detection rates are used as quality measures to analyze the proposed mechanisms.

Abstract (sommario):

O objetivo deste trabalho é apresentar uma nova abordagem, baseada no conceito de números fuzzy, para detecção de bordas em imagens digitais chamado FUNED (Fuzzy Number Edge Detector). A técnica de detecção de bordas implementada pelo FUNED considera uma vizinhança local dos pixels da imagem, definida pelo usuário e, baseado no conceito de números fuzzy, é verificado se um pixel pertence ou não aquela região da imagem, com base na intensidade dos tons de cinza que compõem a região. O pixel que não pertence à região é então classificado como um possível pixel de borda. Através de uma função de pertinência, a técnica proposta fornece uma matriz de pertinência em tons de cinza e, pela escolha de um limiar, as bordas da imagem são segmentadas. Para a modelagem do problema, os tons de cinza são considerados como números fuzzy e, para cada pixel gi,j da imagem, calcula-se a sua pertinência em relação a uma determinada região, considerando os vizinhos que possuem níveis de cinza próximos de gi,j. Ao considerar os valores de cinza como números fuzzy, incorpora-se a variabilidade inerente dos valores de cinza de imagens, proporcionando assim uma abordagem mais adequada ao tratamento de imagens digitais, em comparação ao tratamento clássico, baseado em uma formulação analítica. Para avaliação do desempenho da técnica, foram usadas imagens sintéticas e imagens reais em tons de cinza, obtidas na literatura, e realizados testes qualitativos e quantitativos. Para a realização dos testes quantitativos, foi desenvolvida uma nova metodologia de avaliação de detectores de bordas baseada na análise ROC. O processo de avaliação desenvolvido considera diferentes medidas, que são tomadas comparando-se as bordas obtidas com as bordas ideais. Os resultados da avaliação de desempenho mostraram que o FUNED é eficaz computacionalmente quando comparado aos detectores de Canny e de Sobel e, também a outras abordagens fuzzy. A técnica permite ao usuário o ajuste dos seguintes parâmetros: o tamanho da vizinhança local, o suporte de um número fuzzy e o limiar. O ajuste desses parâmetros proporciona diversas possibilidades de visualização das bordas de uma imagem, permitindo a escolha de detalhes da imagem. A implementação computacional do FUNED é intuitiva e com bom desempenho tanto para obtenção de bordas como em tempo de processamento, sendo adequada para aplicações em tempo real com implementação em hardware.
The purpose of this work is to introduce a new approach, based on fuzzy numbers, for edge detection in gray level images. The proposed approach is called FUNED (Fuzzy Number Edge Detector). The edge detection technique, implemented by FUNED, considers a local neighborhood of image pixels, defined by the user and, based on fuzzy numbers concept, it is verified whether a pixel belongs to that image region, according to the gray level intensity in the region. The pixel that does not belong to the region is then classified as a possible edge pixel. Therefore, through a membership function, the proposed technique provides a membership matrix in gray levels and, through the choice of a threshold, the image edges are segmented. For the modeling of the problem, the gray levels are considered fuzzy numbers and, for each pixel gi,j of the image, it is computed its membership regarding to a specific region, considering the neighbors presenting gray levels near gi,j. When considering gray-values as fuzzy numbers, the inherent variability of the image gray values are incorporated, thus promoting a more powerful approach for the treatment of digital images as compares with the classic treatment based on analytical formulation. For the assessment of the performance of the technique, it was used gray-level synthetics and real images, obtained from the literature, and qualitative and quantitative tests were carried out. To achieve the quantitative tests, it was developed a new methodology for evaluating edge detectors based on ROC analysis. The evaluation process developed considers various measures, that are taken by comparing the edges obtained with the ideal edges. The results of the assessment showed that the FUNED is more computationally efficient when compared to the results obtained by Canny and Sobel detectors and, also to other fuzzy approaches. The technique allows the user to adjust several parameters. The adjustment of these parameters provide several image edge visualization possibilities, which allow the choice of details in the image. The computational implementation of FUNED is intuitive and with good performance both for obtaining edges as in processing time, being suitable for real time applications with hardware implementation.

In this paper, we propose a new edge operator for edge detection of noisy blurred images.Our new operator "fuzzy-edge- operator" based on the theory of fuzzy sets performs edge detection of noisy blurred images faster and more perfectly than other existed operators in both speed and resolution. In the edge detection of a noisy blurred image, the conventional edge operators may require noise elimination and noise suppressing processes which may lose some original important information of edge. On the other hand, edge detection systems using our fuzzy-edge-operator can detect edge directly without preprocessing noise. Also, the results of edge detection using our fuzzy-edge-operator in both speed and cost are much better because the edge detection system using fuzzy-edge-operator is composed of coincidence, XOR and comparators only. Experimental results of noisy blurred images are given.From our experimental results, it shows that the performance of fuzzy-edge-operator for edge detection is much more satisfactory than that of other operators in considerations of noise tolerance, speed and cost.

Abstract (sommario):

In this thesis we investigate how artificial intelligent techniques, namely fuzzy logic and genetic/evolutionary algorithms can be used for digital image processing applications. We demonstrate our techniques with respect to two main research areas: removal of heavy impulse noise from corrupted gray scale images and edge detection in digital images. Very often fuzzy logic systems need to deal with large number of rules. This results in two major design issues: (i) How to formulate the fuzzy knowledge base using human expertise and experience? (ii) How to reduce the high computational power and the high processing times required? In this thesis we use evolutionary algorithms (including coevolutionary algorithms) to learn fuzzy knowledge bases to handle the design issue (i) described above, while using multi-layered and hierarchical fuzzy logic systems to reduce the number of rules and hence the computational overhead involved, thereby addressing issue (ii) stated above. In this research, when fuzzy rules are learnt using evolutionary algorithms, each individual in the evolutionary algorithm is appropriately encoded to uniquely represent the fuzzy knowledge base. The fitness of each individual in the evolutionary algorithm is calculated with respect to a predefined reference. In the case of an algorithm learning to enhance a digital image this reference is often associated with the uncorrupted perfect image. Designing multi-layered and hierarchical fuzzy structures involves breaking down the total number of rules, to be fed into multiple fuzzy layers in the system. This process needs careful consideration in forming the appropriate fuzzy layers as well as deciding the parameters to be input to different layers, so that the desired result is obtained with highest precision using the least computation time. Coevolutionary algorithms are powerful tools that can be used in situations where several factors contributing towards the system performance need to be learnt simultaneously. Here multiple populations consisting of candidate solutions are evolved in parallel and the fitness of individuals in each of the population are evaluated by forming a vector of candidate solutions selected from each population. The artificial intelligence techniques briefly described above will be used in this thesis with application to enhancement and edge detection in digital images.
