This paper presents a new approach for black and white conversion of greyscale images. The algorithm can be easily modified to work on colour images by changing the comparison pattern of the peaks. It uses a scanning method for black pixel peaks and an independent threshold associated to a histogram of the scanned area. The results have been good for different types of documents.
