Abstract

Segmentation and morphological analysis of microvessels in immunostained histological tumour sectionsA fully automatic segmentation and morphological analysis algorithm for the analy- sis of microvessels from CD31 immunostained histological tumour sections is presented. The algorithm exploited the distinctive hues of stained vascular endothelial cells, cell nuclei and background, which provided the seeds for a region-growing algorithm in the 3D Hue, Saturation, Value (HSV) colour model. The segmented objects, identified as microvessels by CD31 immunostaining, were post-processed with three morphological tasks: joining separate objects that were likely to belong to a single vessel, closing ob- jects that had a narrow gap around their periphery, and splitting objects with multiple lumina into individual vessels.
