| Summary: | Video compression standards is one of the key contributions of the electrical and electronics engineering discipline. The latest video standard is the High Efficiency Video Coding (HEVC) or H.265 which has a very high computational complexity. This project proposes the pixel topology algorithm which reduces the computation time spent in block mode decision. It is based on the early detection of predictive unit without passing through the fourth depth that is detection way for H.265. This technique is applied in two phases. First, calculate the cost of each frame depending on the eight models of prediction unit. Second, the frame with minimal cost determines the suitable prediction unit which is used for partitioning the current frame. The project produces significant savings in encoding time and reduction of computation complexity in a robust version which maintains high image quality and suitable encoding rate for transfer over networks. |
