Abstract: With the increasing use of multimedia techniques, image compression requires higher performance as well as new features and also with the expansion of the telemedicine through the internet, the necessity of transmission of a great volume of images through medias of low speed, making impracticable to some applications, like cooperative diagnosis. A solution can be the use of hybrid techniques of compression as proposed in this study. This study deals with BDH technique, which is used to the compression of color images. In BDH technique, Huffman coding and Difference coding with Binary Plane Technique are combined. The BDH technique is compared with Binary Plane Technique (where no difference coding is used) and JPEG. Experimental results show that BDH improves compression rate compared to Binary Plane Technique.
