“…It provides a boost to the sensitivity of the information in images and presents enhanced input to carry out other procedures. In skin cancer recognition the research utilized an anisotropic diffusion filter [ 34 , 35 ], median filter [ 35 , 36 ], Dull Razor [ 37 , 38 , 39 , 40 ], Adam Huang algorithm [ 41 ], Wiener filter [ 42 ], Bilateral filter [ 43 ] and Gaussian and Gaussian Blur filter [ 44 , 45 ], Z-score transformation [ 46 ], contrast-limited adaptive histogram equalization [ 47 , 48 ], adaptive histogram equalization [ 49 ], global-local contrast stretching [ 50 ], color constancy with shades of gray [ 51 ], adaptive gamma correction [ 52 ], gamma and correction [ 53 ], etc., for enhancement and noise removal in the skin recognition process.…”
