An efficient inter layer up-sampling filtering algorithm in scalable video coding （SVC） was proposed. Based on different component-sensitive of the human vision system

scheme assigns up-sampling filters depending on the sensi-tivity priority of the image component in order to increase the coding efficiency was proposed. Particularly

a 6-tap filter is assigned for luminance component and a bilinear filter is for chrominance components. The experiment results show that our proposed scheme maintains the performances of coded bit-rate and PSNR value without any noticeable loss

and provides significant reduction in computational complexity. As a result

it can be applied in the inter layer spatial inter-polation of SVC.
