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.

WebbIn this paper, the shape template matching algorithm is applied to pharmaceutical blister packaging defects detection. The algorithm can determine whether there is a positioning region of the sheet or pieces missing through search algorithm to locate the template image and comparing the difference of gray value between the detection region and the … 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.

WebbThe feature-based approach to template matching relies on the extraction of image features, such as shapes, textures, and colors, that match the target image or frame.This approach is usually achieved using neural networks and deep-learning classifiers such as VGG, AlexNet, and ResNet. [citation needed] Convolutional neural networks (CNNs), … 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.

WebbIn addition, the integral kernels that characterize local shape geometry enable the shape signature to be robust with respect to undesirable perturbations while retaining discriminative power. Use of our shape signature is demonstrated for shape matching based on a number of synthetic and real examples.
