In this paper we propose a supervised sparse representation method for face recognition. We assume that the test sample could be approximately represented by a sparse linear combination of all the training samples, where the term “sparse” means that in the linear combination most training samples have zero coefficients. We exploit a heuristic strategy to achieve this goal. First, we determine a linear...
With the progress in image processing and pattern recognition, computerized tongue diagnosis has received considerable recent research interest. In computerized tongue diagnosis, reflection is unavoidable in the acquisition of tongue images. Correct detection of the highlight area and removal of reflection in tongue images is requisite and would greatly affect the performance of tongue texture analysis...
Developing accurate and robust palmprint verification algorithms is one of the key issues in automatic palmprint recognition systems. Recently, orientation based coding algorithms, such as Competitive Code (CompCode) and Orthogonal Line Ordinal Features (OLOF), have been proposed and have been attracting much research attention. Such algorithms could achieve high accuracy with high feature matching...
