Segmentation of medical images in the half-byte data format

The paper presents a method of image segmentation applying the half–byte data format. The half–byte data format is an image representation that consists of two types of image pixel values, pixel base values and calculated pixel difference values. Original image pixel value is obtained by joining pixel difference value and corresponding base pixel value. The layout of base pixels value is in accordance with detected regions. Segmentation based on the half–byte image date format uses simply algorithm and is attractive computationally. The paper presents also results of segmentation medical test images converted into the half–byte data format.
