SINGLE PIXEL DEPENDENT PREDICTION WITH DOWNSAMPLING AND INTERPOLATION

Abstract — In the past decades, video coding technologies have greatly promoted the development of digital multimedia contents related industry. To satisfy the rapid increasing demand for high-definition (HD) and ultra-HD (UHD) video contents, a higher requirement for more efficient video coding has been brought forward. In this paper we propose a new approach for efficient video compression. We mainly focus on intraframe coding that performs compression techniques on any one of the frames in video sequence. A single pixel based lossless prediction (SPLP) along with downsampling and interpolation is used to achieve a better compression ratio compared to existing system. SPLP is an enhancement of H.264/MPEG-4 standard, which employs pulse code modulation for better prediction. Along with SPLP, a checker board pattern downsampling and adaptive weighted interpolation techniques are used to improve the performance
