Different from the quality assessment algorithms for general images, the face image quality assessment need to consider more practical factors that directly affect the accuracy of face recognition, face verifcation, etc. In this paper, we present a two-stream convolutional neural network (CNN) named...
Learning to Rank for Blind Image Quality Assessment We propose a blind image quality assessment (BIQA) model using learning to rank (LTR) method in order to overcome the defects of the existing BIQA model. I... L Zheng,G Zhang,Y Cai - 《Proceedings of International Conference on Computer ...

In recent years, Face Image Quality Assessment (FIQA) has become an indispensable part of the face recognition system to guarantee the stability and reliability of recognition performance in an unconstrained scenario. For this purpose, the FIQA method should consider both the intrinsic property and ...
The face quality assessment is based on four metrics including pose estimation, sharpness, brightness and resolution, and the frame with the best face quality is considered as a keyframe. Experimental tests were carried on several datasets in order to prove the efficiency of authors' method ...
Standardization of face image quality, ISO/IEC 29794-5, is in progress. Bad illumination, facial pose and out-of-focus are among main reasons that disqualify a face image sample. This paper presents several algorithms for face image quality assessment. Illumination conditions and facial pose are ...
