Abstract While shadow can give useful information about size and shape of objects, it can pose
problems in feature detection and object detection, thereby, it represents one of the major
perturbator phenomenons frequently occurring on images and unfortunately, it is inevitable.
“Shadows may lead to the failure of image analysis processes and also cause a poor quality of
information which in turn leads to problems in implementation of algorithms.” (Mahajan and
Bajpayee, 2015). It also affects multiple image analysis applications, whereby shadow cast by
buildings deteriorate the spectral values of the surfaces. Therefore, its presence causes a
deterioration in the visual… More >
