Energy efficiency has become one of the most important topics in computing. High Efficiency Video Coding (HEVC) still adopts the hybrid coding framework. The blocking artifacts still exist and deblocking filter in the HEVC used to reduce the blocking artifacts. Deblocking filter can improve both the subjective and objective video quality, has lowered computational complexity and allows parallel processing...
The OFDM system based on the fractional Fourier transform (FRFT-OFDM) is robust against fast-fading channel. However, the performance of anti-jamming is not analyzed. In this paper, the anti-jamming performance of the FRFT-OFDM system under multitone jamming (MTJ) and linear frequency modulated (LFM) jamming is evaluated. The evaluation is carried out by calculating bit error rate with probability...
Image filtering is an important problem in image processing. Many algorithms such as adaptive filter, total variation method in this field are efficient and practical. In this paper, the local homogeneity method is employed which result in the homogeneity image (H-image). The high and low values of the H-image correspond to possible region boundaries and region interiors respectively. Finally, an...
