This paper introduces an adaptive low power decoding process with temporal prediction method for common video. This method can be used to reduce the decoding time and reduce the decoding power consumption by skipping the decoding process of some frames and reducing the frame rate. With the temporal prediction, it is different from the certain frame skipping scheme in the temporal scalable decoding...
This paper proposes an adaptive solution of temporal scalable decoding process with frame rate conversion method for surveillance video. It realizes the adaptive skipping scheme in the temporal scalable decoding process based on the content of the pictures. By analyzing the relationship between motion vector energy and the video quality loss of the same frame in probability, chooses the suitable form...
High-definition (HD) and super-high-definition (SHD) videos become more and more popular for various video applications, including video capture and playback on portable devices. Because of the resolution mismatch between HD/SHD video and the low resolution screen of portable devices, the video is fully decoded and then sown-sampled for the display, which causes a waste of both computational power...
H.264/AVC introduces the variable block size macroblock mode for motion estimation, which brings huge computational cost. In this paper, a novel fast inter macroblock mode decision algorithm for H.264/AVC has been proposed. The proposed algorithm evaluates the modes based on residual information. The residual is obtained after the motion search of P16 ?? 16 mode or P8 ?? 8 mode. Then the characteristic...
Video surveillance has been widely applied in broad area to improve the public safety and to protect the residential privacy. Because of the requirements in storing the video data over a period of time for future use and because of the huge size of the raw video data, video compression technique has been integrated into the video camera of the surveillance system. As a state-of-the-art video compression...
This paper presents a high efficiency method to decide the inter mode of the H.264/AVC encoder. Although rate-distortion optimization (RDO) improving the video quality in video compression largely, its high computational complexity brings huge time cost. The key idea of this paper is to reduce the candidate modes by the underlying relation between motions and macro block partition types. Thus, a motion...
This paper presents an adaptive quantization method by adjusting the rounding offset for scalar quantization adopted in AVS 1.0 part 2 zengqiang profile. The rounding offset is chosen adaptively based on minimum transform coefficients energy difference for quantization, and the transform coefficient energy difference is calculated by the sum of absolute distortion before quantization and after dequantization...
