WebFeb 11, 2024 · Python, OpenCVで画像のアルファブレンドとマスクによる合成処理を行う。OpenCVの関数を使わなくてもNumPyの機能で実現できるので合わせて説明する。NumPyの配列操作のほうが簡単かつ柔軟なのでオススメ。ここでは以下の内容について説明する。OpenCVでアルファブレンド: cv2.addWeighted() OpenCVでマスク ... WebAug 23, 2024 · Bitwise OR. This function calculates the disjunction of the pixels in both images. Here we perform an element-wise product of the array, we will not eliminate pixels but it merges both images. bit-or = cv2.bitwise_or (img1,img2) cv2_imshow (bit-or) Bitwise OR operations. In the above output, we merged both images using the OR function.
