In order to resolve the problem of image feathering in the region

the formula of weight function is presented based on the depth information of the region and every pixel in the region is processed according to the weight. As a result

the closer the pixel is to the region boundary

the less the correction of pixel value is

and the farther the pixel is to the region boundary

the more the correction of pixel value is. This method of image feathering is also tested using real images. In order to overcome the time consuming disadvantage of iterative algorithm for computation of region depth

a fast algorithm is also proposed and tested using convex

concave and cross polygon region. The experiment shows that the method proposed above is very effective and can acquire good results in image feathering of the region.
