If the contribution made by illumination component of image is decreas

1.	If the contribution made by illumination component of image is decreased and the contribution of reflectance component is amplified, what will be the net result?(a) Dynamic range compression(b) Contrast enhancement(c) All of the mentioned(d) None of the mentionedI have been asked this question during an online exam.The above asked question is from Homomorphic filtering in portion Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» Correct answer is (C) All of the mentioned For EXPLANATION I would say: The illumination component of an image is characterized by a slow SPATIAL variation and the reflectance component of an image VARIES abruptly particularly at the junction of dissimilar OBJECTS, so, if the contribution made by illumination component of image is decreased and the contribution of reflectance component is amplified then there is simultaneous dynamic range compression and contrast stretching.
