A proper way of scaling low frequency DCT coefficients is utilized by illumination normalization. The images captured under varying illumination have low contrast. For contrast stretching the ...
My second doubt it is possible to introduce normalization and equalization to this code. How would I do that? Someone can Help me pls. Thank you. 2 Comments Image Analyst on 6 Apr 2018 I don't understand the question. And what are Hi, Hj, Ii, and Ij? Hi and Hj don't...
Finally in BPDHE, histogram equalization is implemented after assigning a new dynamic range for each sub histogram. In order to maintain the mean brightness, brightness normalization is applied to ensure that the enhanced image has similar mean brightness of the input image. Research by Praveen et...
