Various video applications such as mosaicing and object insertion require blending of image regions. The blending quality is often measured subjectively by considering the similarity of the blended image to each of the input images and the visibility of the seams among stitched regions. This paper presents a novel method to blend the moving objects in the related background mosaic based on an adaptive alpha blending method. In order to compute the best possible value for the alpha blending coefficient in dynamic mosaic updating, here we propose a fuzzy method based on relative speed and scale parameters of moving objects. Conducted experiments show that the proposed method improves the...
