Application of Improved Watershed Algorithm in Image of Device Wall Segmentation

This paper presents a new method for region merging to solve the over-segmentation after watershed segmentation.Then with the initial watershed segemention,region merging according to the region average gray value similarity is proposed and in this course the region average gray value is a rough characteristic about the region while the region area becomes bigger,so a new similarity function is introduced.The results show that the new similarity function avoids the case that the object is merged with the background falsely and gives the base to get parameters of the disrepaired device.
