Two Systems for the Detection of Melanomas in Dermoscopy Images Using Texture and Color Features
TL;DR: It is concluded that color features outperform texture features when used alone and that both methods achieve very good results, i.e., Sensitivity = 96% and Specificity = 75% for local methods.
Journal ArticleDOI
Improving Dermoscopy Image Classification Using Color Constancy
TL;DR: The results show that color constancy improves the classification of multisource images, increasing the sensitivity of a bag-of-features system from 71.0% to 79.7% and the specificity from 55.2% to 76% using only 1-D RGB histograms as features.
Journal ArticleDOI
A Survey of Feature Extraction in Dermoscopy Image Analysis of Skin Cancer
TL;DR: This work thoroughly explores the several types of features that have been used in DIA, and discusses their relevance and limitations, as well as suggestions for future research.
Journal ArticleDOI
A System for the Detection of Pigment Network in Dermoscopy Images Using Directional Filters
TL;DR: An automatic system that performs its detection in dermoscopy images and uses an AdaBoost algorithm to classify each lesion regarding the presence of the pigment network.
Journal ArticleDOI
Development of a clinically oriented system for melanoma diagnosis
TL;DR: A clinically computer aided diagnosis system is proposed for melanoma diagnosis that learns to detect various relevant dermoscopic criteria using text labels and combines medical information and feature fusion to diagnose the lesions.
