An Image Automatic Registration Approach Based on Watershed Algorithm
Dong Wang, Qing Tang, Ge Chen · Advanced engineering forum · 2012
A new image registration method is proposed in this paper. Most microscopic images, such as concrete surface, have not obvious features which most image registration method can depend on. Firstly contours of different color area are extracted automatically with improved watershed algorithm. Then centroid of these contours is used to obtain transformation matrix between two adjacent images. Experiment shows, this method can solve the registration problem in image mosaics very well.
