Paper Abstract

This paper proposes a lossless image compression method utilizing the neighboring pixels to determine the reference point values. The proposed method scans every pixel row by row and assigns a 2-bit reference point value to each pixel by comparing its intensity value to the neighboring pixels' intensity values. The intensity value will be stored to a new file only when the comparison fails to find a neighborhood pixel with the same intensity value. The compression is achieved as only the information of 2-bit reference point values for all pixels and certain intensity values are required for storage. The suggested method is tested on various types of images and the results show that it performs well for most of the images.
