This project addresses the challenge of recovering the true texture of a surface from a single grayscale or color image under *uneven illumination. Uneven lighting often masks or distorts the ...
A Python implementation of frequency-domain filtering techniques for grayscale images, covering noise removal, spatial-frequency convolution equivalence, and illumination correction via homomorphic ...
Abstract: When the spectrum of multiplicative noise is overlapped with the spectrum of the true signal, the effect of noise elimination is bad using homomorphic filtering method. The principle of ...
