Abstract :
An algorithm for re-sizing H.264/AVC video in DCT space is presented. We demonstrate that a frame re-sizing operation can be represented as multiplication by fixed matrices and propose an efficient computation scheme. The proposed approach is general enough to accommodate re-sizing operations with arbitrary factors conforming to the syntax of H.264 video. It shows a good PSNR than the spatial domain bilinear and bicubic spline interpolation at much reduced cost.
