This paper presents a novel method for protecting privacy sensitive regions inside a digital frame. The purpose is achieved by deteriorating the visual quality of privacy sensitive region by adding probability model based random noise to nonzero quantized transform coefficients of the region. The probabilistic model based noise is generated based on the information from neighboring macroblocks and...
In this paper we propose a fast candidate selection method in RMD step of Intra prediction. The proposed method consist of two steps, in the first step, coarser steps between the prediction directions are used as possible candidates for comparison, where the coarser step size is a function of Prediction Unit size. This way we find the dominant direction with minimum cost. In the second step, the dominant...

Improved performance of Intra Prediction in HEVC in comparison to H.264/AVC is primarily due to two main feature enhancements, first is increase in the number of intra prediction directions and secondly due to the support for larger transform sizes. Using lagrangian based rate distortion measure to decide the appropriate prediction direction and Transform Unit size requires calculation of bits generated...
This paper describes a method to optimize the power needed to display a video by better illuminating the regions of interest compared to the rest of the video. This method identifies the regions of interest by utilizing parameters from the digital video codecs. It also employs temporal and spatial filters to improve perceptual quality of the video. For our experiment we used MPEG-2 [1] encoded video...
