[0026] reference figure 1 As shown, the present invention discloses a method for detecting false positives of vascular calcification based on brightness analysis, including the following steps:
[0027] S1. Use a calcification detection algorithm to obtain a calcification candidate area for the blood vessel image. The calcification detection algorithm can use conventional fixed threshold, dynamic threshold, contrast or extreme value algorithms, which are not specifically limited in the present invention.
[0028] S2. Perform morphological analysis on the calcification candidate area to detect whether there is a large area of calcification filling the blood vessel and whether there is a small area calcification that occurs at the bifurcation of the blood vessel;
[0029] S3. Adjust the detection threshold of large area calcification based on the brightness analysis for the condition of large area calcification filling blood vessels, and use the large area calcification detection th...
