Gaussian Noise and Haar Wavelet Transform Image Compression on Transmission of Dermatological Images

Telemedicine provides medical information and services using telecommunication technologies. Teledermatology, is a special part in the medical field of dermatology and one of the most common applications of telemedicine and e-health. Telecommunication technologies are used in Teledermatology to exchange medical information over a distance using audio, visual and data communication. Medical images require compression; Wavelet-based image compression provides substantial improvements in picture quality at higher compression ratios. An ideal image compression system must yield high quality compressed image with high compression ratio; this ratio can be achieved using transform-based image compression, however the contents of the image affects the choice of an optimum compression ratio and the optimum compression method. This paper presents image compression method. Haar wavelet transform, which can be applied to compress dermatology images before the transmission through a communication channel.
