Abstract

This paper proposes a hybrid interpolation algorithm for reconstruction of chrominance components to original resolution which are sub-sampled as 4∶2∶0 format. The proposed approach combines a simple interpolation method with a more complex one. It adaptively selects the most appropriate interpolation method for a given pixel position using our own decision criteria in order to provide high-quality images while reducing the complexity efficiently.

子采样色度分量重建的混合插值算法
提出了一种混合插值算法,用于将4∶2∶0采样后的色度分量重建到原始分辨率。该方法结合了一种简单的插值方法和一种更复杂的插值方法。针对给定的像素位置,采用自适应的决策准则选择最合适的插值方法,在有效降低复杂度的同时提供高质量的图像。
