Recover intrinsic textures from unevenly lit images using homomorphic filtering, frequency-domain analysis, and chromaticity-preserving color correction

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 ...

Adaptive wideband homomorphic filtering for electromagnetic interference source imaging testing system

Abstract: This paper presents an adaptive wideband homomorphic filtering which is directly applied to suppress the coherent noise in electromagnetic interference source imaging testing system. When ...
