WebApr 12, 2024 · Step 3: Read the Image with OpenCV. OpenCV uses the cv2.imread method to convert the image file into a Python object. Python3 starryNightImage = cv2.imread (“starryNight.jpg”) The aforementioned variable contains a bitmap of the starryNight image file. You can display this original unedited image by using: WebSeven steps to perform image pre-processing for OCR. 1. Normalization. This process changes the range of pixel intensity values. The purpose of performing normalization is to bring image to range that is normal to sense. OpenCV uses normalize () function for the image normalization.
