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.
