    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.
