I am trying to run Lucas kanade algorithm on DM6446 based board. To begin with the algorithm, I have chosen two simple images. The image contains square as an object, so practically it can have 4 feature points
We apply a Viola-Jones face detector to determine which, if any, of the resulting feature clusters represent a trackable person. This algorithm is tested using two identical standard cameras mounted on a mobile robot platform. Results are presented demonstrating detection and tracking of a person ...
algorithm opencv image-processing tracking feature-detection 1个回答 0投票 算法中几乎没有基本假设。 具体针对您的情况: 整个补丁在两个图像上都可用。 可以计算patch位置的梯度。 由于梯度通常是通过有限差分来估计的,因此边界的余量取决于选择的有限差分系数。 最常见的选择是使用图像上的中心一阶。 这意味着...
内容提示: Pyramidal Implementation of the Lucas Kanade Feature TrackerDescription of the algorithmJean-Yves BouguetIntel CorporationMicroprocessor Research Labsjean-yves.bouguet@intel.com1 Problem StatementLet I and J be two 2D grayscaled images. The two quantities I(x) = I(x,y) and J(x) = ...
The Matlab code is written to show the same steps as in the Literature, not optimized for speed. But also an inverse Lucas Kanada algorithm in c-code for quick template tracking is included, which also contains pixel weighting for more robustness. ...
