WebWe define a hole to be a bounded simply-connected region obtained by removing vertices and/or edges so that its boundary only consists of vertices of degree 2 or 3. We do not consider a simply connected region with “dangling vertices” as a valid hole since these vertices have degree 1. (Fig. 1 (c) illustrates such an invalid hole.)

WebFirstly, the region_of_interest() function could be optimized for speed by using OpenCV's built-in cv2.fillPoly() function instead of the slower numpy implementation. Secondly, the draw_lines() function could be improved by calculating the slope of the line and only drawing lines with slopes within a certain range.
