Suppressing noise in digital images is more significant in the field of image processing. In this paper, a novel impulse noise detection method is introduced based on fuzzy sets. Generally fuzzy sets are associated with type-1 vagueness, but interval-valued intuitionistic fuzzy sets (IVIFSs) are tied up with type-2 linguistic uncertainty in which the width of the interval represents vagueness. The...
In this paper, we present an entropy-based contrast enhancement method in the wavelet domain. The proposed method is used in the HSI color space. The low-frequency coefficients in the wavelet domain are modified by the global histogram-based approach. The high-frequency coefficients are scaled by magnifying the entropy of the contrast defined in the wavelet domain. The contrast of the intensity component...
