Abstract :
This paper presents a method of low-complexity intra-prediction for H.264/AVC that uses pseudo local decoded image (PLDI). The PLDI is created using a Hadamard transform and used for intra-prediction mode decision. Our experimental results show that the proposed method can reduce the complexity of the intra-prediction process with acceptable losses in picture quality.
