Abstract:

A matching resampling filter algorithm was proposed to solve the problem of resampling techniques in scalable video coding. The isolated designing of down- and up-sampling filters leads to poor filtering performance. The proposed algorithm uses the acquired parameters of the down-sampling filter to derive the corresponding un-sampling filter to achieve the matching purpose. It can improve not only the video quality but also the encoding performance of the spatial scalable video coding. Compared to the simulation results of the joint scalable video model (JSVM) under the same condition, the performance of the proposed matching resampling filter algorithm is significantly improved that the peek signal to noise ration (PSNR) is increased by 1.6 dB in average.

Key words: communication, scalable video coding, down-sampling, up-sampling, re-sampling
