Opencv template matching rotation invariant

Web6 de nov. de 2014 · A padded pixel is usually given a value of 255 or 0 (black or white, depending of the rotation algorithm). Now, template_matching does match all of the template, so it will try to match even the region that contains only padded pixels and no useful information, which it most likely won't find in the query image. Web2 de out. de 2024 · 1 1 There is no algorithm that is truly invariant to rotation of template, and to noise some algorithms may be more robust (i would advice zero normalised cross correlation with can be efficiently implemented using fft).
