Fast Intra Prediction Algorithm for H.264 High Profile Based on Image Texture

Abstract:

Article Preview

H.264/AVC standard uses rate-distortion optimization framework with heavy calculation and full search algorithm to select the best mode of each macroblock. Besides, 8×8 luma block prediction is added to high profile, which makes the search algorithm process more complicated. In order to reduce the amount of calculation, a filter method based on image texture feature and image complexity is adopted in this paper. Experiment results show that the new algorithm achieves an average saving of 43%-57% in encoding time ,with negligible effect on bitrate and PSNR.
