Algorithms for color image edge enhancement using potential functions
D. Sindoukas, Nikolaos Laskaris, S. Fotopoulos · IEEE Signal Processing Letters · 1997
This letter deals with the color image edge enhancement issue using clustering ideas and based on the use of potential functions (Parzen windows). Two algorithms are proposed. The first uses potential functions (PF's) and selects the output as the vector maximizing the PF. The second one elaborates further by employing the mountain clustering method and modifying it appropriately. Both algorithms are robust in the presence of noise, Gaussian and impulsive.
