Intra Prediction Algorithm for Video Frames of H.264

Abstract

Prediction is the process of duplicating the information contained in the macro block using previously coded data.H.264 supports intra prediction. It is having two types intra prediction 16x16, 4x4.In 16x16 having 4 modes and 4x4 having 9 modes of prediction. This prediction uses previously coded data of current frame to form prediction. The frames which are intra coded using intra prediction are called I-frames. This paper will give a brief description about different modes of intra prediction and this algorithm    will gives best intra prediction method by calculating the sum of absolute difference values for each mode of prediction.
