Webb1 juli 2024 · In this article, we’ll see how to use Generalized Hough Transform with OpenCV to do shape based matching. This algorithm takes points along the contours of an object with the help of Canny filter. Then, for each point, the gradient orientation is calculated from two Sobel filters, one horizontal and one vertical.

WebbThe key of shape based matching, or linemod, is using gradient orientation only. Though both edge and orientation are resistant to disturbance, edge have only 1bit info (there is an edge or not), so it's hard to dig wanted shapes out if there are too many edges, but we have to have as many edges as possible if we want to find all the target shapes. christine morris jackson mylifeWebb10 dec. 2024 · OpenCV provides an easy to use a utility function called matchShapes that takes in two images ( or contours ) and finds the distance between them using Hu Moments.
