Skin lens: Skin assessment video filters

This paper presents a framework for real-time skin analysis. Our system consists of two filters for skin redness analysis and pigmented skin lesions analysis. In skin redness analysis, we search for skin regions in video frames and assess size and degree of redness in skin regions. In order to analyze pigmented skin lesions we localize potential moles of different sizes utilizing multiple difference of Gaussian filters and apply trained Support Vector Machine and K-Nearest Neighbors to eliminate non-mole candidates from the previous stage. After finding mole candidates we present information about the symmetry and border irregularity of candidate moles. To test real-time performance of our system a prototype application on iPhone 4S and iPhone 5S was implemented.
