Automatic shadows detection in high resolution images
Main Article Content
Abstract
This paper presents a development of filter for shadows detection in high resolution
digital image. Shadows, many times, are very useful elements as information of
contextual objects in digital images. Usually, in many image analysis and
interpretation applications, shadows are critical to solve problems to automatic objects extraction and interpretation. For this reason, shadow segmentation is an
important step in image analysis and many techniques have been proposed to solve
the problem automatically. The proposed techniques identify automatically the
shadows which are present in high resolution images. The results showed that the
proposed filter is efficient in identifying shadows for a large class of scenes.
