62 Based on Blood Vessel Edge Feature Fundus Fluorescein Angiography Image Splicing

According to fundus fluorescein angiography images characteristics, propose a image splice method based on vascular edge feature. First, carries on the pretreatment to the fundus fluorescein angiography image in the foundation, wavelet edge detection algorithm to detect edge of blood vessels. Then, based on chain code feature matching method described. Finally, using a local area based on gray level information of the image fusion method angiographic image series. Data processing results show that the method can be an ideal mosaic effect.
