Figure 12

Comparison of plaque boundary detection. (a) IVUS image 1 to be processed. (b) Boundary detection results. The red lines and the green lines indicate the boundaries detected by the proposed method and by the method with the normal PMD filter [6], respectively. The white lines are the desired boundaries.
