Abstract :
Cloud detection and removal forms an important need for change detection studies. A small amount of cloud cover may misinterpret the crucial information in disaster management applications. Although several cloud detection techniques exist, there is a critical need to apply these techniques in real time and obtain the cloud free images quickly to support real time decisions.
