Reconstructed Error and Linear Representation Coefficients Restricted by l1‐Minimization for Face Recognition under Different Illumination and Occlusion

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017
The problem of recognizing human faces from frontal views with varying illumination, occlusion, and disguise is a great challenge to pattern recognition. A general knowledge is that face patterns from an objective set sit on a linear subspace. On the proof of the knowledge, some methods use the linear combination to represent a sample in face ...
