Sažetak
The distortion of the images transmitted over satellite channel can noticeably depend on various conditions and circumstances. In telemedical images, the distortion can be fatal and result in misdiagnosis and wrong treatment. Satellite communication for application in telemedicine is considered. The results have shown that just-noticeable-distortion can lead to misdiagnosis in the case of transmission of pulmonary X-ray images and it is concluded that the area of telemedical use of JND profile must be carefully chosen. Human visual perception of grey images is investigated, performed experiments and calculated the JND for the experimented case. Minimal fatal error distortion (MFED) is introduced and some aspects of it are discussed. The JND of the X-ray original and the distorted image is calculated and shown that JND difference can be used to locate the distortion.
