Abstract:

The task of face verification is made more difficult when the illumination conditions of image capture are not constrained. The differences in illumination conditions between the stored images of the client and the probe image can be lessened by the application of photometric normalisation. Photometric normalisation is the method of pre-processing an image to a representation that is robust to the illumination conditions of image capture. This thesis presents experiments comparing several photometric normalisation methods. The results demonstrate that the anisotropic smoothing pre-processing a

Abstract:

Face verification is a challenging pattern recognition problem. The face is a biometric that, we as humans, know can be recognised. However, the face is highly deformable and its appearance alters significantly when the pose, illumination or expression changes. These changes in appearance are most notable for texture images, or two-dimensional (2D) data. But the underlying structure of the face, or three dimensional (3D) data, is not changed by pose or illumination variations. Over the past five years methods have been investigated to combine 2D and 3D face data to improve the acc

Abstract:

This thesis describes a face verification system that is smart-card-based. The objectives were to identify the key parameters that affect the design of such a system, to investigate die general optimisation problem and test its robustness when each key parameter is optimised. Some of these parameters have been coarsely investigated in the literature in the context of the general face recognition problem. However, the previous work only partially fulfilled the requirements of a smart-card-based system, in which the severe engineering constraints and limitations imposed by smart cards have to be

Abstract:

Identity verification systems are an important part of our every day life. A typical example is the Automatic Teller Machine (ATM) which employs a simple identity verification scheme: the user is asked to enter their secret password after inserting their ATM card; if the password matches the one prescribed to the card, the user is allowed access to their bank account. This scheme suffers from a major drawback: only the validity of the combination of a certain possession (the ATM card) and certain knowledge (the password) is verified. The ATM card can be lost or stolen, and the password can be

Human face recognition is an important area in the field of biometrics. It has been an active area of research for several decades, but still remains a challenging problem because of the complexity of the human face. In this thesis we describe fully automatic solutions that can locate faces and then perform identification and verification. We present a solution for face localisation using eye locations. We derive an efficient representation for the decision hyperplane of linear and nonlinear Support Vector Machines (SVMs). For this we introduce the novel concept of $\rho$ and $\eta$ prototypes

Abstract:

This thesis has investigated how to cluster a large number of faces within a multi-media corpus in the presence of large session variation. Quality metrics are used to select the best faces to represent a sequence of faces; and session variation modelling improves clustering performance in the presence of wide variations across videos. Findings from this thesis contribute to improving the performance of both face verification systems and the fully automated clustering of faces from a large video corpus.

Nowadays, there is growing interest in face detection applications for unconstrained environments. The increasing need for public security and national security motivated our research on the automatic face detection system. For public security surveillance applications, the face detection system must be able to cope with unconstrained environments, which includes cluttered background and complicated illuminations. Supervised approaches give very good results on constrained environments, but when it comes to unconstrained environments, even obtaining all the training samples needed is sometimes

碩士<br>國立臺灣科技大學<br>自動化及控制研究所<br>104<br>This thesis discusses the face recognition with the application of identity verification. In order to narrow down the range in an image to find the face, the Haar-like AdaBoost is used for the face detection. Then KAZE algorithm is first applied here for the feature extraction in the face recognition. KAZE feature algorithm was first proposed in 2012, and the KAZE features can be described and detected in a nonlinear scale space by means of nonlinear diffusion filtering. In this research, we adopt new algorithm KAZE, instead of using the traditional method

碩士<br>國立中央大學<br>資訊工程學系<br>101<br>Face verification has many applications. The critical problem which lots of researchers concern is how to apply to real-world. In order to robust orientation, translation and scaling of face images, we extract SIFT features of face images which is built dictionary of sparse representation. We propose two kinds of method to extend dictionary via K-means and information theory(extended dictionary and incremental dictionary). Experiments show that we can increase sparseness of sparse coefficients efficiently, also can improve verification rate and reconstruction e

碩士<br>國立清華大學<br>資訊工程學系所<br>106<br>In recent years, due to the fantastic applications revealed in the mass media are progressively walking out to the reality, face recognition is getting more and more attention to people all over the world. Between the two modes of face recognition, verification is simpler and more suitable than identification in some practical applications such as authentication. To describe the information in human faces more elaborately, we prefer the local appearance-based methods among the various face recognition approaches. In this thesis, we studied three local appearan

Abstract:

As one of the most successful application of image analysis and understanding, face recognition has recently received significant attention, especially during the past few years. There are at least two reasons for this trend the first is the wide range of commercial and law enforcement applications and the second is the availability of feasible technologies after 30 years of research. The problem of machine recognition of human faces continues to attract researchers from disciplines such as image processing, pattern recognition, neural networks, computer vision, computer graphics, and psycholo

It may include the entrance control system, financial management, criminal detection, and computer certification etc., which all require a set of strong identity verification system. Therefore, identity verification technique will play a more important role in the informationalized society of the 21st century, and how to construct a set of safe and convenient identity verification system has been the hot study

Firstly, to speaker recognition problem, we use wavelet transform to decompose speech signal into high and low frequency coefficients, then we apply difference traditional methods include PCA, LPCC, Fractal, and WTFT to extract low or high frequency as feature, which combined probabilistic neural network classifier to match voiceprint. This shows the proposed method will improve recognition rate and efficiency. Besides, to face recognition, we will obtain cumulative gray curve after 2D

Abstract:

博士<br>國立成功大學<br>電腦與通信工程研究所<br>100<br>This thesis proposes three different approaches for face recognition. In the first approach, a novel feature extraction method for face recognition is proposed. The digital curvelet transform is used to extract the face features. In the method, an original image is convolved with 6 Gabor filters corresponding to various orientations and scales to give its Gabor representation. Then, the Gabor representation is analyzed by the ridgelet transform followed by the two-dimensional principal component analysis (2DPCA) which computes the eigenvectors of the ridgel
