Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Illumination with different lighting levels or angles is an important problem for classification of an individual in face recognition. To overcome this issue, generally classification algorithms are applied after pre-processing of the images to get rid of the low contrast regions to increase the accuracy of recognition. In this work, we use Steerable Gaussian Filter at the pre-processing step for all training and testing samples. In the classification step, we use the recently proposed “Classification via Sparse Reconstruction Vector (CSRV)“ algorithm. The performance of our approach is compared with that of the “Principal Component Analysis (PCA)” algorithm in terms of recognition rates (RR). Experiment results show that the CSRV algorithm has a better performance than that of the PCA algorithm with higher RR even for poorly illuminated images taken from Yale Database B.
