Alpha-dependent template matching (matchTemplate) #4726

WebCode # read the template emoji with the alpha channel template = cv2.imread(imagePath, cv2.IMREAD_UNCHANGED) channels = cv2.split(template) zero_channel = np.zeros_like(channels[0]) mask = np.array(channels[3]) # all elements in alpha_channel that have value 0 are set to 1 in the mask matrix mask[channels[3] == 0] = 1 Web25 de jul. de 2013 · One reason is that MatchTemplate isn't rotation invariant. In SLAM the robot learns it's unknown environment while exploring it. The robot builds a map in it's own reference frame. Typically the origin of the reference frame is where the robot starts SLAM. So this reference frame can have another orientation as the ground truth reference frame. marcatori a getto d\u0027inchiostro portatili
