Algorithm of Completion for Strong Orientational Texture Images
Lei He · Computer Engineering and Applications Journal · 2006
Natural photographs and strong orientational texture images sometimes may contain stains or undesired objects covering significant portions of the images,where the removal of a foreground object creates a hole in the images.We present an inpainting algorithm for strong orientational texture/color images existing in our environment to fill in the holes.Becauce of the strong orientation,the algorithm synthesizes the missing part by image patches selected from orientationally local areas.Along the orietation of texture /color distribution or the constrained orietation to search,we select a source block B_(TN) near a missing block B_(T) firstly,and find the most similar block B_(SN) to B_(TN),then update B_(T) by the block B_(S) near B_(SN).To reduce blockiness,the boundary between blocks is further computed as a minimum cost path through the error surface at the overlap before updating B_(T).A few examples for a variety of texture images are given to demonstrate the effectiveness of our method.
