Webb5 aug. 2010 · Template matching is an image processing problem to find the location of an object using a template image in another search image when its pose (X, Y, θ) is unknown. In this article, we implement an … 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. hide instagram chat https://jana-tumovec.com

WebbThe key of shape based matching, or linemod, is using gradient orientation only. It's quite a dilemma. However, gradient orientation has much more info than edge, so we can easily match shape orientation in the overwhelming img orientation by template matching across the img. Speed is also important.

Webb10 jan. 2024 · matchShape can be applied at the end to the rest of contours or you can also apply to all contours (I suggest first approach). Each contour is just an array so you can hold the reference contours in an array and compare them with the others at the end. After doing 3 steps and then applying matchShape is very good on my side.
