—A multilevel gray scale image can quite efficiently be segmented by the multilevel sigmoidal (MUSIG) activation function based on equal and fixed class responses, ignoring the heterogeneity of image information content. The optimized version of MUSIG (OptiMUSIG) activation function can be generated with the optimized class responses from the image content(More)

Automatic data clustering through determination of optimal number of clusters from the data content, is a challenging proposition. Lack of knowledge regarding the underlying data distribution poses constraints in proper determination of the inherent number of clusters. A differential evolution (DE) algorithm based approach for the determination of the(More)
