Get polygons from edges in OpenCV -


i have image want extract lines (a vascular network), using hough line algorithm. first preprocess image, use canny edge detection generate binary image.

i want polygon/an array of joined line segments representing shape of vascular network. applying hough line transform directly on image yields mediocre results, partly because edge detection means each vessel represented 2 lines on each side, instead of single line.

i'm new opencv , image processing in general, i'm going wrong way. suggestions, or recommended literature?

hough may not best tool job. hough give straight lines or other geometric shapes. not designed follow detailed pattern this.

given image, read research papers solve this. here few examples search on google scholar. if don't work you, citations should lead down other paths.
