Image Enhancement
1010503Image EnhancementImage enhancement refers to data processing that aims to increase the overall visual quality of an image or to enhance the visibility and interpretability of certain features of interest in it. During acquisition of remotely sensed imagery, the potential range of pixel values may not be fully utilized in recording the data owing to the atmospheric effect and the limitations of the sensing system. Consequently, the obtained data may have a poor quality, such as a low contrast, an overly dark tone, or much radiometric noise. Eradication of such problems lies in image enhancement that may be carried out either nonspatiall…
