摘要

Performance of face recognition systems drop drastically when blur effect is present on facial images. In this paper, we propose a new approach for blurred face recognition. Our method is based on a measure of the level of blur introduced in the image using a no-reference blur metric. The face recognition process can be performed with any facial feature descriptor to allow the combination of alternative methods for overcoming data acquisition problems introduced in an image. To assess its efficiency, the approach has been applied with Gabor wavelets,Local Binary Patterns (LBP) and Local Phase Quantization (LPQ) facial descriptors on the FERET data-set.Experimental results clearly show the strength of this method at overcoming the, problem ,caused by various forms of blur whatever the facial feature descriptor are implemented.
