Journal ArticleDOI
Integration of morphological preprocessing and fractal based feature extraction with recursive feature elimination for skin lesion types classification.
TL;DR: The proposed layered structure identifies all the three classes of skin diseases with a highly acceptable classification accuracy of 98.99%, 97.54% and 99.65% for melanoma, dysplastic nevi and BCC respectively.
Journal ArticleDOI
Extraction of features from cross correlation in space and frequency domains for classification of skin lesions
TL;DR: The present work explicates the extraction of spatial and the spectral features from conspicuous regions of skin lesions on the basis of similar visual impacts with the appropriate kernel patches, using the Cross-correlation technique.
Journal ArticleDOI
Optimal selection of features using wavelet fractal descriptors and automatic correlation bias reduction for classifying skin lesions
TL;DR: The scheme presented in this paper surpasses the performance of the other state-of-the art techniques for the differentiation of melanoma from other skin abnormalities.
Journal ArticleDOI
Morphological operations with iterative rotation of structuring elements for segmentation of retinal vessel structures
TL;DR: A hysteresis thresholding, guided by some morphological operations has been employed to obtain the binary image excluding other unwanted areas of the blood vessel from its background, and a maximum accuracy and an average accuracy of 95.65 and 94.31% respectively have been achieved.
Proceedings ArticleDOI
Mathematical morphology aided shape, texture and colour feature extraction from skin lesion for identification of malignant melanoma
TL;DR: Different shape, texture and color features have been extracted from a set of dermoscopic images and malignant melanomas have been classified using SVM classifier with 85.71% sensitivity.
