Abstract: Edoscopy videos are used for finding the bleeding regions. The edge regions are first detected and removed. Because the edge regions and the bleeding regions share same Hue value and the bleeding regions and the non -bleeding regions has same luminance, a canny edge detector is used to detect the edge regions in L channel. Canny edge detector is used because it can detect more edge pixels and preserve more bleeding pixels. Canny edge detector performs based on canny edge algorithm. The methodology in edge removal algorithm includes edge detection, edge dilation and edge masking. Thus the identification of the bleeding is carried out.

Keywords: Canny edge detector, Edge detection, Super-pixel segmentation, Edge dilation, Edge removal
