Abstract :
A new method for Natural Rendering of Color Image based on Retinex (NRCIR) is proposed. Here, the word ¿natural¿ means that the ambience of image (warm or cold color impression) should not be changed after enhancement. Furthermore, the treatment should not introduce any additional light sources and should not produce halo effect or amplify blocking effect. Inspired by Retinex theory and histogram rescaling techniques, the proposed method tries to realize natural rendering of image with respect to the constraints listed above. Extensive tests with different types of natural images have been performed. The obtained results clearly demonstrate the efficiency of the proposed method.
