Abstract
In image wrapping, the post-filtering is necessary to avoid aliasing effect. Here, we develop a hybrid space-variant directional filtering for post-processing. In order to reduce the computation, we classify the filter area as three blocks: constant, oriented, and irregular. The constant and irregular blocks are local average filtering and elliptical weighted average filtering. In oriented model, we propose a new filtering method called elliptical weighted adaptive directional moving average filter. In the experiments, we show that our method may correct the distorted images and have better results, with better subjective quality, especially with high magnification ratio, such as four times or more.
