WebJan 3, 2024 · A binary image is a monochromatic image that consists of pixels that can have one of exactly two colors, usually black and white. Binary images are also called bi-level or two-level. This means that each pixel is stored as a single bit—i.e., 0 or 1. The most important library needed for image processing in Python is OpenCV. WebTo produce a binary image from an indexed image, first convert the image to a grayscale image using ind2gray. Algorithms The "adaptive" method binarizes the image using a locally adaptive threshold. imbinarize computes a threshold for each pixel using the local mean intensity around the neighborhood of the pixel.
