METHOD FOR PROCESSING MEDICAL BLOOD VESSEL IMAGE

摘要

The present invention relates to a method for processing a blood vessel image comprising: i) an adaptive regional binarization step of dividing the image into regions, setting a critical value for each region based on an average value or a standard deviation value of image pixels within each of the regions, and then binarizing blood vessels and non-blood vessels based on the critical value; ii) a morphology calculation processing step of performing morphology calculation for correcting noise that is included in the image which has undergone the adaptive regional binarization; iii) a step of thinning for thinning the image which has undergone the morphology calculation and for extracting blood vessel lines; iv) a blood vessel direction and width measuring step of identifying the extracted blood vessels within each of the regions from the image which has undergone thinning, and measuring the width of the blood vessels by analyzing the gray profile of the blood vessels that is perpendicular to the direction of the blood vessels; and v) an adaptive Gabor filtering step of selectively applying the most appropriate Gabor filter to each of the regions by considering the direction and the width of the blood vessels, which are measured in step iv).
