Повний текст джерелаIn den Anfängen der Computergrafik war die Forschung hauptsächlich von dem Anspruch getragen, realistisch aussehende synthetische Bilder zu erstellen. Im Gegensatz dazu ist die nicht-photorealistische Computergraphik, ein Untergebiet der Computergrafik, welches in den frühen 1990er Jahren gegründet wurde, vor allem motiviert durch Konzepte und Prinzipien der traditionellen Kunst wie Malerei, Illustration und Grafikdesign. Diese Arbeit beschäftigt sich mit der künstlerischen Verarbeitung von zweidimensionalen Bildinhalten und präsentiert mehrere neue automatische Verfahren für die Erstellung von vereinfachten künstlerischen Darstellungen von Farbbildern, Videos und 3D- Renderings. Wichtigste Neuerung dieser Techniken ist die Verwendung des Strukturtensors als eine einfache und effiziente Möglichkeit, Informationen über die lokale Struktur eines Bildes zu erhalten. Konkret werden die folgenden Beiträge gemacht. Erstens wird eine umfassende übersicht über den Strukturtensor gegeben. Insbesondere werden verschiedene Methoden für die Integration des kleineren Eigenvektorfeldes des geglätteten Strukturtensors entwickelt, und die Überlegenheit des geglätteten Strukturtensors gegenüber dem populären Edge-Tangent-Flow demonstriert. Zweitens werden separable Implementierungen des bilateralen Filters und des Difference of Gaussians Filters vorgestellt. Durch die Anpassung der Filter an die lokale Struktur des Bildes werden Bildfehler vermieden, wobei der Vorgang rechnerisch effizient bleibt. Zusammengenommen bieten beide Techniken eine effektive Möglichkeit, um einen Cartoon-ähnlichen Effekt zu erzielen. Drittens wird eine Verallgemeinerung des Kuwahara-Filters vorgestellt. Durch die Anpassung von Form, Umfang und Orientierung der Filter an die lokale Struktur werden Bildfehler verhindert. Außerdem werden direktionale Bildmerkmale besser berücksichtigt und betont, was zu schärferen Kanten und einem malerischen Effekt führt. Neben der single-scale Variante wird auch eine multi-scale Variante vorgestellt, welche im Stande ist, eine höhere Abstraktion zu erzielen. Viertens wird eine Technik vorgestellt, die auf der Kombination von flussgesteuerter Glättung und Schock-Filterung beruht, was zu einer intensiven Verstärkung und Betonung der direktionalen Bildmerkmale führt. Alle vorgestellten Techniken erlauben die zeitlich kohärente Verarbeitung von Einzelbildern eines Videos oder einer dynamischen 3D-Szene, ohne dass andere aufwendige Verfahren wie zum Beispiel die Berechnung des optischen Flusses, benötigt werden. Darüberhinaus können die Techniken effizient implementiert werden und ermöglichen die Verarbeitung in Echtzeit auf einem Grafikprozessor (GPU).

Повний текст джерелаIn 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 0.1 dB improvement in Chrominance component for the texture view after applying this filter in picture based filtering. Moreover, a design of an in-loop filtering with Fast Bilateral Filter for 3D-HEVC standard is proposed. Bilateral filter is a filter that smoothes an image while preserving strong edges and it can remove the artifacts in an image. Performance of the bilateral filter in picture based level for 3D-HEVC is evaluated. Test model HTM- 6.2 is used to demonstrate the results. Results show up to of 20 percent of reduction in processing time of 3D-HEVC with less than affecting PSNR of the encoded 3D video using Fast Bilateral Filter.

When bilateral filter smoothes images with highly corrupted noise by using small-scale parameters, a large amount of noise cannot be removed. Conversely, if large-scale parameters are used, the edges in images will become blurred. In this thesis, we propose a new adaptive filtering method based on content analysis. The method partitions images into background and edge, and then uses bilateral filter to smooth images with different scales to improve visual results. We first detect the edges in an image, and then convert the grayscale image to binary image by binarization processing. Since human is more sensitive to noise than the edges, the background is smoothed with large-scale parameter and the edges are smoothed with small-scale parameter. In this way, noises in edges and background can be eliminated separately. Experimental results show that our method smoothes images while preserving edges even the image was highly corrupted by noise, and achieves better results than that of the bilateral filter.

Due to many known or unknown factors, the most important problem encountered is the presence of the image noise during the acquisition procedure-no matter what nature or medical images and the interference is also very difficult to avoid. Therefore, many image denoising algorithms have been proposed to address the problem in the past decades. Among them, the bilateral filter receives much attention since it achieves not only excellent performance but also low complexity. The bilateral filter considers the spatial and the intensity relation simultaneously. Due to the simplicity in implementation, the bilateral filter has been widely used in many image denoising applications. In our work, we will discuss the structure of bilateral filter in detail, and then propose adaptive scheme to adjust the filter parameters. According to the simulation result, the proposed method is with higher performance than that of convention bilateral filter not only reducing noise but also visual quality for both nature images and medical images.

The social media has been gaining popularity due to the popularity of internet and mobile devices, recently. Many people used to using mobile devices to take pictures and film videos in daily life. Also, they are uploading to the social media to share to others immediately. Then, a large number of applications of face beautification have already hit the store shelves. The primary goal of this thesis is to make the system of adaptive face beautification to achieve the goal of facial beautification without doing any adjustment of parameters. The proposed system of facial beautification is composed of three main parts: pre-treatment, skin smoothing and histogram analysis. In the pre-processing phase, the YCbCr color to change the transition of space is used firstly. Then, the skin color segmentation to find the human skin color parts is conducted. Finally, the median filter to remove the noise is applied. In the skin smoothing phase, using the bilateral filter on the basis are preserved to make the face smooth. This method also keeps the facial features effectively. Finally, the histogram analysis is used to find the most suitable data for the bilateral filter smooth weight. The adaptive gradations to adjusting the whole image and color is developed and verified. The adaptive facial beautification is finished according the methods in this thesis.

Super-resolution is a technique majoring to restore the lost information when image scaling, such like the edge blurry in image scaling up, or it cannot describe the original object details in low-resolution image, and it will cause the quality decrease when image scaling. To reach the goal of light-weight Super-resolution, this research is major to reconstruct the image details and reducing the impact on image quality of image scaling without increasing excess computational cost. Based on conventional image interpolation scheme, the proposed technique utilizes the high frequency component of the image generated by the bilateral filter to compensate the detail distortion during scaling. By analysis the image standard deviation and local gradient, the proposed algorism redefines the bilateral filter with range filter and noise reduction filter, it will improve the characteristic of object details when image scaling and Simultaneously improve the image quality by noise reduction. In addition to improving the image quality, the research also focused on reducing the computational complexity and hardware cost. We are devoted to implement the hardware of real-time applications with line buffer-based algorithm.
