Opencv shape distance and matching

WebThe shape context distance between two shapes is defined as the symmetric sum of shape context matching costs over best matching points. The final value of the shape distance is a user-defined linear combination of the shape context distance, an image appearance distance, and a bending energy. Parameters: shapeContextWeight WebThis tutorial will show how you can match similar shapes having slight variations with Python & OpenCV code. Interested in Computer Vision ? Subscribe to my ...

Web13 de out. de 2015 · Look for template-like keypoints in your scene by doing distance-calculations in M dimension : Each keypoint is like a point in 3D, and matching 2 keypoints as similar is nothing but calculating the distance of the points in 3D and saying "close enough "!. You now have 2 sets of keypoints, and a list of plausible keypoints matches.
