Shadow Detection and Removal in Colour Images using MATLab
Shadow detection and removal is an important task when dealing with colour structure images. Shadows are generated light fall in the object. Because the shadow region change during the day based on the position of the sun and the sky fall on the structures. Shadows are decrease in the light that reaches a surface area. Shadow area is detected and segmentation based on image analysing process. Some noise Factors will affect the detection result due to the complexity of the condition. primary colour component image loaded from the shadow and salt and pepper noise is removed from the contra harmonic filter and average colour is computed and the shadow can detected by using binary and morphological function. And hypothesis test to detect shadows from the images and then energy function concept is used to remove the shadow from the image.
