Sparse Contribution Feature Selection and Classifiers Optimized by Concave-Convex Variation for HCC Image Recognition

<div>The cell gray-scale images and the cell binary images. (a<sub>1</sub>, a<sub>2</sub>) are normal cell gray-scale image and (b<sub>1</sub>, b<sub>2</sub>) are the matching binary images. (a<sub>3</sub>, a<sub>4</sub>) are HCC cell gray-scale image and (b<sub>3</sub>, b<sub>4</sub>) are the matching binary images.</div>
