Abstract: The transmission and archiving of medical images are among the most important operations in telemedicine. Indeed, the collaboration platforms have to ensure video conferencing, medical images and patient data transfer and archiving. However, the big volume of this kind of images represents a major obstacle for the work of a tele-staff. In order to overcome this problem, we suggest a new archiving and transmission protocol that we call 'wavREPro.JPEG'. Its process consists of two phases. In fact, before the information broadcast, this protocol reduces images by Discrete Wavelet Transforms and compresses them by the classic JPEG. At the reception step, it enlarges images after their decompression. Experimental results have demonstrated that our proposed method is more efficient than the classic JPEG compression. Effectively, it offers more minimisation in terms of network bandwidth consumption and storage space.
