Object Oriented Shadow Detection and Correction by Image Inpainting in Remote Sensing Images

摘要

Satellite images provides rich information about earth resources. Remote sensing technology helps to derive these data. They have many applications in landscape, change detection, town planning etc. But, mainly in urban areas these images get affected by the shadows. The elevated objects are the reason for the appearance of shadows there. When the light source are blocked shadows are created. Shadows lowers the quality of images or it may affect the information provided by them. Thus for the correct image interpretation or to extract information it is important to detect shadow regions and compensate them. So far many algorithms and methods had been developed in shadow detection and removal. Most of them are based on pixel level detection and correction. An object.
