Abstract

DubaiSat-1 (DS1) captures multispectral images with 5-meter resolution using three visible bands red (420 to 510 nm), green (510 to 580 nm), blue (600 to 720 nm) and one near-IR band (760 to 890 nm). It also has a panchromatic channel with 2.5-meter resolution (420 to 720 nm). [1] Under certain conditions, degradation in quality might occur over DS1 captured images. The aim of this project is to enhance the quality of the image in terms of resolution, sharpness and color quality. It is well known that the enhancement procedure is a very difficult task due to the significant noise increase resulted from any sharpening action. Moreover, sometimes the color of the captured images might become saturated, thus some areas will be given false coloring (i.e., some colors will be presented as gray instead of their original colors).
