Web14 de nov. de 2024 · The bitwise XOR (exclusive or) performs an exclusive disjunction, which is equivalent to adding two bits and discarding the carry. The result is zero only when we have two zeroes or two ones. XOR can be used to toggle the bits between 1 and 0. Thus when used in a loop toggles its values between 1 and 0. i = i ^ 1. 例如: WebYou can add two images by OpenCV function, cv.add or simply by array addition, res = img1 + img2. Both images should be of same depth and type, or second image can just be a scalar value. Bitwise operations inclue bitwise AND, OR, NOT and XOR operations. They will be highly useful while extracting any part of the image, defining and working ...
