- Abstract
Image mosaicking is a process of assembling multiple images to create an image with a larger field of view. It is used in different studies, but some errors, like ghosting or parallax effects, could occur when the images contain dynamic elements. To avoid the failure of the mosaic and to solve these errors, a new method that searches an optimal seamline for dynamic mosaicking is presented. By finding regions that are similar between the images, and regions that are not alike, the seamline was computed by going through the similar regions and by avoiding the not common regions. To achieve this, a combination of Canny edge detector, and the outliers and inliers from the RANSAC method were used to identify these regions. Then, the regions were incorporated in an intensity difference to create a map that reveals them. Thus, the optimal seamline was computed by going through the similar regions and by avoiding the unalike regions. The experimental results show that the proposed approach is capable of generating robust mosaics against ghosting and parallax effects.
