Different Thresholding Techniques in Image Processing: a Review

EasyChair Preprint no. 7327

Abstract

Document data is captured through optical scanning or digital video, resulting in a file of picture elements, or pixels, which serves as the raw input for document analysis. These pixels are samples of intensity values taken in a grid pattern throughout the document page, with intensity values ranging from OFF (0) to ON (1) for binary pictures, 0-255 for grayscale images, and 3 channels of 0-255 colour values for colour images. The initial stage in document analysis is to process this image so that it may be analysed further. Thresholding is used to convert a grayscale or colour image to a binary image, noise reduction is used to remove superfluous data. The goal of this paper is to summarize some thresholding technique for image processing.
