A Study on Edge Detection Based on Local Image Self Similarity |
| |
| Abstract: | A kind of local image self similarity measure is defined. It is proved that under this measure, ideal edge blocks possess very good local self similarities. According to this feature, a novel edge detecting method based on local image self similarity is proposed. Experimental results show that edges with or without noise can be satisfactorily detected. |
