An approach combining a simple local representation method with a k-nearest neighbours-based direct voting scheme is proposed for face and speaker recognition. This approach rises computational problems that we effectively solve through an approximate fast k-nearest neighbours search technique. Experimental results with the XM2VTSDB face database and the Eurtrans-I speech database are reported showing the effectiveness of the proposed approach.
