due to inhomogeneous illumination and other reasons
the collected images have features of large dynamic range and details blur.So this paper proposes a method for enhancing the color images based on information fusion of multi-color space and homomorphic filters.First
in RGB color space
the three components are processed by using the homomorphic filtering and the adaptive clipping stretch methods respectively to eliminate illumination effect and enhance the local details effectively.Then
in HSV color space
the V component of modified by the nonlinear transformation function structured is used to make illumination compensation to the image.And the H and S component of the original image is used to restore the color information.The experimental results suggest that the proposed method shows better in the aspects of dynamic range compression
enhancement of the detail of bright and dark areas and keeping the color consistency.
