OBSERVER DEPENDENT WAVELET IMAGE COMPRESSOR

♣ This work was supported by AGH Technical University grant no. 10.10.120.39 ABSTRACT The image compression by means of wavelet technique is considered in this paper. The proposed solution takes advantages of the current observer eye position rather than the image content. The noninvasive eye-pursuit system determines the zone of observer’s interest and sends the information back to the image capturing system, which maximises the image resolution inside the zone of interest, while the remaining part of the image is sent at lower resolution. This method, however limited to the real-time observations, makes possible an up to 12-times compression of a single image without any loss of quality (e. g. colour definition) inside the observer specified area.
