Abstract |
|
The H.264 which is also named Advanced Video Coding compression standard in video processing which results in good quality of video. The H.264 standard in video compression allows fast block matching algorithm to estimate the displacement of pixels in a search area limit which reduces the complexity of computing the motion vectors. In this paper we discussed on a 2D logarithmic search algorithm which gives the best match when compared to other block matching algorithm. Next, we check quality of video of predicted frames by computing PSNR. Thus using SP-line interpolation we increase the PSNR value for a set of specified frames. |
