Abstract:
Many applications require automatic image analysis for different quality of the input images. In many cases, the quality of acquired images is suitable for the purpose of the application. However, in some cases the quality of the acquired image has to be modified according to needs of a specific application. A higher quality of the image can be achieved by Image Enhancement (IE) algorithms. The choice of IE technique is challenging as this choice varies with the application purpose. The goal of this research is to investigate the possibility of the selective application for the IE algorithms.

Abstract:
Smoothing and noise reduction of images is often an important first step in image processing applications. Simple image smoothing algorithms like the Gaussian filter have the unfortunate side effect of blurring the image which could obfuscate important information and have a negative impact on the following applications. The bilateral filter is a well-used non-linear smoothing algorithm that seeks to preserve edges and contours while removing noise. The bilateral filter comes at a heavy cost in computational speed, especially when used on larger images, since the algorithm does a greater amount of

Abstract:
Indiana University-Purdue University Indianapolis (IUPUI)<br>In this thesis, we describe a different implementation for in loop filtering method for 3D-HEVC. First we propose the use of adaptive loop filtering (ALF) technique for 3D-HEVC standard in-loop filtering. This filter uses Wiener–based method to minimize the Mean Squared Error between filtered pixel and original pixels. The performance of adaptive loop filter in picture based level is evaluated. Results show up to of 0.2 dB PSNR improvement in Luminance component for the texture and 2.1 dB for the depth. In addition, we obtain up to 0

Abstract:
碩士<br>國立清華大學<br>資訊工程學系<br>96<br>Additive noise removal is an important and practical problem in image processing. Bayesian and other approaches have been proposed to restore the corrupted images. More methods are proposed to preserve signal details while removing noise such as the bilateral filtering. This filter is a weighted average of the local spatial and range distance over a set of data. However, users have to find acceptable two parameters σS and σR in bilateral filters manually by their experience. In this paper, we propose an algorithm which can generate two parameters automatically b

Abstract:
碩士<br>國立臺灣科技大學<br>資訊工程系<br>103<br>As a result of noises on the depth maps captured by a Time-of-Flight (ToF) camera, 3D applications such as 3D reconstruction will generate low quality models. Hence, the process of denoisng depth maps is important. This study proposes a novel combination of denoising methods with the idea of the temporal denoising plus a bilateral filter. The temporal denoising represents the way that this study firstly selects a middle frame with multiple adjacent frames from all depth maps captured from different angles and then renew each depth value in the middle frame by

Owing to the changeable weather is just like clouds or haze constituted by atmospheric particles, then this phenomenon cause the low contrast presented in satellite image and lose many information on the surface of the earth. Therefore, in this paper we propose an issue for dehazing to single satellite image, which is to enhance the contrast of image and filter the h

碩士<br>國立成功大學<br>電腦與通信工程研究所<br>102<br>In traditional stereo matching method, global method is more accurate but spending more time, and have more correct rate in occlusion area. On the contrary, local method is usually fast but have bad performance, and easily is influence by noise. This paper proposed a novel method to compute disparity between two images. It is based on local method, but its cost be aggregated in like-global way. This aggregation is processed by a weight map which created by bilateral filter concept. Every pixel transfer its own cost information to all pixels on the same obje

Bilateral filtering is a nonlinear filtering approach is different from the linear filter that was widely used. It can obtain better performance than that of linear filters. The linear filters usually remove the important details on medical images. On the other hand, bilateral filters can consider the spatial and intensity relationships in pixels and preserve the important details, which are very significant on analyzing medical images.

Zur Verminderung des Rauschens sehr hochauflösender Satellitenbilder existieren eine Vielzahl von Glättungsalgorithmen. Die Wirkung verschiedener Tiefpaß- und kantenerhaltender Filter auf das Verhalten eines objektorientierten Segmentierungsverfahrens wird anhand zweier synthetischer Grauwertbilder und einer IKONOS-Aufnahme untersucht. Als Rauschmaß hat sich ein modifiziertes, ursprünglich von Baltsavias et al. [2001] vorgeschlagenes Verfahren bewährt, in dem je Grauwert nur die Standardabweichungen der gleichförmigsten Gebiete berücksichtigt werden. In Vergleich mit synthetisch verrauschten B
