Shadow Detection in Aerial Images Using Side Information

The subject of this project is shadow detection in aerial images using details of the flight: time, position and the plane’s direction during the photograph. Intelligence decoding of images is interested in temporal differences in images. These differences include the unneeded shadow differences, since the image is captured in different time, location and flight directions. The detection method in our algorithm is based on shadow intensity (gray level), shadow direction (based on sun position in specific time and location), sharp changes in the image and object size. After combining all methods, we get a shadows image.
