Implementation Comparison of Intra Prediction Scheme

Abstract

Due to increasing demand of video application such as video conference, video communication, video streaming and storage, video compression is required. Due to this requirement new international standard H.264 & H.265 HEVC are introduce for video compression. These standards improve video compression based on intra prediction. Intra prediction is a technique to enhance compression through use of neighboring pixels to predict current coding block. Intra prediction in H.264 / AVC is executed in the spatial domain, to predict with reference to neighboring samples of previously coded blocks to the left and / or above the block. There are total nine modes used to predict the current block. This work supports 4�4 block size and 16�16 block size for the prediction of the mode. The goal of this work is to reduce the computational complexity of intra prediction and to give accurate prediction result. In this work efficient intra prediction scheme is implemented and compared to literature.
