Texte intégralHEVC has achieved significant coding efficiency improvement beyond existing video coding standard by employing many new coding tools. Deblocking Filter, Sample Adaptive Offset and Adaptive Loop Filter for in-loop filtering are currently introduced for the HEVC standardization. However these filters are implemented in spatial domain despite the fact of temporal correlation within video sequences. To reduce the artifacts and better align object boundaries in video , a new algorithm in in-loop filtering is proposed. The proposed algorithm is implemented in HM-11.0 software. This proposed algorithm allows an average bitrate reduction of about 0.7% and improves the PSNR of the decoded frame by 0.05%, 0.30% and 0.35% in luminance and chroma.

In this thesis, a super resolution using trilateral filter regression with local texture enhancement is proposed. The system consists of two major parts, the interpolation of trilateral filter regression, and local texture enhancement. The trilateral filter is used to fix the disadvantage of the traditional NEDI methods. In the interpolation part, the suitable weights are given for all pixels in the training window by the trilateral filter. Hence, the blocking effect can be reduced in some regions. After interpolations part, the high frequency information of the local texture is added into the enlarged images to improve the texture blurring. Experimental results demonstrate that the proposed method provides superior performance than other well-known approaches in the average PSNR and SSIM. In addition, the texture enhancement achieves better subjective performance by evaluation of observers.

Removing noise while preserving and enhancing edges is one of the most fundamental operations of image/video processing. When taking pictures with digital cameras, it is frequently found that the color images are corrupted by miscellaneous noise, especially images get with high ISO values in low luminance. Hence, noise filtering is a necessary module in digital still cameras. The difficulty of designing noise filter is that the filter will also reduce the sharpness of the image. On the other hand, optical lens imperfections are usually equivalent to spatial low pass filters and tend to result in blurred images. It is customary to apply edge enhancement algorithm on the image in order to improve the sharpness, but this process usually increase the noise level as a by-product. Hence, an efficient noise filter is very important before edge enhancement. In this paper, the efficiency of trilateral filter and other popular filters are compared briefly, and the trilateral filter is implemented by HDL language for image processing chip.

Postacquisition denoising of magnetic resonance(MR) images is of importance for clinical diagnosis and quantitative analysis, such as tissue classification, segmentation, and registration. It is well known that the noise in MR magnitude images obeys a Rician distribution, which not only causes random fluctuations, but also introduces a signal-dependent bias to the data that reduces image contrast . As a consequence, separating signal from noise in those images is particularly difficult. We propose a post-acquisition denoising algorithm called adaptive trilateral filtering to adequately and adaptively remove the random fluctuations and bias introduced by Rician noise. The proposed filter consists of geometric, radiometric, and median-metric components that replaces the intensity value with an weighted average between neighboring pixels associated with an entropy function. In addition, a parameter automation mechanism is proposed to reduce the burden of laborious interventions through a fuzzy membership function, which adaptively responses to local intensity difference. The experimental results indicate that the adaptive trilateral filter outperformed several existing methods in providing greater Rician noise reduction and clearer structure boundaries both quantitatively and qualitatively.

Noise removal is one of the fundamental and essential tasks within image processing. In medical imaging, finding an effective algorithm that can remove random noise in magnetic resonance (MR) images is important. This thesis proposes an effective noise reduction method for brain MR images. The proposed is based on the trilateral filter, which is a more powerful method than the bilateral filter in many cases. However, the computation of the trilateral filter is quite time-consuming and the choice of the filter parameters is also laborious. To address these problems, the trilateral filter algorithm is implemented using parallel computing with GPU. The CUDA, an application programming interface for GPU by NVIDIA is adopted, to accelerate the computation. Subsequently, the optimal filter parameters are selected by artificial intelligence techniques. Artificial neural networks and support vector machines associated with image feature analysis are proposed to establish the automatic mechanism. The best feature combination is selected by the t-test and the sequential forward floating selection (SFFS) methods. Experimental results indicated that not only did the proposed GPU-based version run dramatically faster than the traditional trilateral filter, but this automatic system also effectively removed the noise in various brain MR images. We believe that the proposed framework has established a general blueprint for achieving fast and automatic filtering in a wide variety of MR image denoising applications.
