How to replace the background of AI photos with OpenCV
This article mainly introduces "OpenCV how to achieve AI photo background replacement" related knowledge, editor through the actual case to show you the operation process, the method of operation is simple and fast, practical, I hope that this "OpenCV how to achieve AI photo background replacement" article can help you solve the problem.
Picture
1) attached main program # Daily zoom rows,cols, channels = img_back.shapeimg_back = cv2.resize (img_back, None, fx=0.7, fy=0.7) cv2.imshow ('img_back', img_back) rows,cols, channels = img.shapeimg = cv2.resize (img, None, fx=0.4, fy=0.4) cv2.imshow (' img', img) rows,cols, channels = img.shape # rows,cols must be the foreground image finally After traversing the image, you need to use # conversion hsvhsv = cv2.cvtColor (img, cv2.COLOR_BGR2HSV) # to get masklower_blue = np.array ([78,43,46]) upper_blue = np.array ([110,255,255]) mask = cv2.inRange (hsv, lower_blue, upper_blue) cv2.imshow ('Mask', mask) # corrosion expansion erode = cv2.erode (mask, None, iterations=1) cv2.imshow (' erode', erode) dilate = cv2.dilate (erode, None) Iterations=1) cv2.imshow ('dilate', dilate) # ergodic replacement center = [50,50] # position in the new background picture for i in range (rows): for j in range (cols): if dilate [I, j] = 0: # 0 represents the black dot img_back [center [0] + I, center [1] + j] = img [I, j] # replace the color here Is the BGR channel cv2.imshow ('res', img_back) cv2.waitKey (0) cv2.destroyAllWindows ()
All right! The above matting to change the background is the effect of this code!
2) display other
Let's take a look at another matting app I've been using recently. This matting effect is actually better than my code.
2.1 I won't say that's the original picture-can you guess?
2.2 from comics to reality
2.3 what background do you want to exchange for what background
