Method And Device For Performing Interpolation In Scalable Video Coding

摘要

An interpolating method and a device for interpolating in grade video compression are disclosed. They apply mutual independent accurate interpolation filters to the luminance component and the chroma component, in which, their tap coefficients are mutual independent and the filters can be symmetric or not. And the interpolating result is used in interpolating in scalable video coding for a good effect. The increment of the compression efficiency and the reduction of the complexity can be realized. The interpolating method can be executed in the interpolating device.
