Progressive Medical Image Transmission Using Reversible Integer Wavelet Transform For Telemedicine Application
نویسندگان
چکیده
In this paper, we are proposing a wavelet-based progressive transmission algorithm for medical images. The system should fulfill certain criteria of medical image transmission. To accomplish the target, we have studied several potential integer wavelet transforms and waveletbased image coders that best work for the system. The system is also enhanced with region-of-interest (ROI) coding, which we find valuable to the telemedicine application. We then evaluated the proposed algorithm by comparing it to the JPEG2000 coding scheme by lossless compression (bit rate) and progressive fidelity transmission (PSNR vs. bit rate) performance. The results show that the proposed algorithm offers comparable performance with JPEG2000 scheme. Key-Words: Progressive transmission, Integer wavelet transform, SPIHT, Medical images.
