Abstract: To deal with the broken edge and conglutination edge in segmentation image by canny algorithm,an algorithm after segmentation is put forward which deal with the canny edge image multitimes with morphological open operator and close operator based on different structure units.Firstly,the algorithm used some disc structure units which dimension is increasing to process the edge image.At the same time,in order to lessen the interacting of the objects,the algorithm filtered the objects before next close operation which have had good segmentation.Lastly,in order to break the conglutination between different objects,the algorithm processes the image of objects which have bad segmentation with open operation by appropriate structure unit.The experiments’ result shows that the algorithm could joint the broken edge and break the conglutination effectively.The Algorithm improved the result of canny algorithm and depressed the reliance on the parameters of canny algorithm.
