First, installdbrandopencv-python: pipinstalldbr opencv-python OpenCV supports WebP decoding, which simplifies the process: fromdbrimport*importcv2defmain():try:filename=sys.argv[1]license=""iflen(sys.argv)>2:withopen(sys.argv[2])asf:license=f.read()frame=cv2.imread(filename)reader=Barcode...
pip install opencv-python Next, create a main.py file and add the following code to it: import cv2 # Open the video file video_input = cv2.VideoCapture('dog.mp4') # Get video properties including width, height, and frames per second (FPS) fps = video_input.get(cv2.CAP_PROP_FPS) fr...

Tried a few libraries, to process these scans with Python (like cv2), but in general, edge detection does not work, because many times there's no visible edge, receipts are rotated or partly pushed under each other. Is there any (AI) solution that can help me to first extrac...
OpenCV ships out-of-the-box with a very limited set of GUI tools. These GUI tools allow us to display an image to our screen (cv2.imshow), wait for/record keypresses (cv2.waitKey), track mouse events (cv2.setMouseCallback), and create simple GUI elements such as sliders and trackbar...
