WebAs suggested in the comments, you have two ways to do this. You can either iterate through each image and run the cv2.cvtColor method or you can use the formula to convert from RGB to grayscale directly. OpenCV uses the SMPTE Rec. 601 conversion formula, which is: Y = 0.299*R + 0.587*G + 0.114*B. Let's cover both methods. Web4 de jan. de 2024 · OpenCV has a function to do this, cv2.equalizeHist (). Its input is just grayscale image and output is our histogram equalized image. Input Image : Recommended: Please try your approach on {IDE} first, before moving on to the solution.
