Processing of the retinal cone image based on the MATLAB
摘要
Abstract
BACKGROUND:The cone cel for the image retina adaptive optical imaging system is characterized by the relatively concentrated gray distribution, vague window edge, the existing pseudo outline, and the adhesion of edge photograph. Looking for a suitable processing algorithm of the cone image to get the clear outline is the key content for the future work. <br> OBJECTIVE:To perform edge extraction of the retina cone cel image and get clear edge profile of the cone cel based on the MATLAB. <br> METHODS:According to the retinal image of the different parts of 30 normal subjects, based on Mat lab image processing toolbox, we could preprocess the cone cel image, edge extraction and process morphological, and get the clear edge profile of the cone cel image. The cel numbers of processed image was counted, the cone distribution characteristics were analyzed, and then the feasibility of this study which designed image processing algorithm applied to the study of the distribution characteristics of cone cel s were verified. <br> RESULTS AND CONCLUSION:A clear outline of the retinal cones image was obtained successful y. From the results of cone cel ’s density, as far away from the center fovea of macula, the cel density presented a trend of reduction;from the center fovea of macula partial range 0.5° to 1°, the retinal cones density decreased rapidly. The findings indicated that the algorithm of the image processing designed in this study can be used to study the retinal characteristics of the cones distribution.关键词
