WebMay 10, 2024 · Document image binarization (also referred to as document image segmentation) is an important preprocessing step. It aims to segment the input document image into text (foreground) and non-text (background). The segmentation performance will directly affect subsequent tasks in the DAR system. WebImage binarization is the process of representing an image pixel in binary format by assigning a value to the pixel as either 0 or 1. Before conversion to binary, the image can be in either gray-scale having pixel value between 0 to 255 or color, i.e., a pixel having value between 0 to 255 for each of the red, green, blue (RGB) channels separately.
