With the recent advances in smart phones and their ease of availability to common man, researchers are exploring efficient algorithms for face recognition on mobile devices for entertainment applications. The limited memory and processing power on mobile devices pose significant challenge to the satisfactory of popular face recognition algorithms like LBP, ICA, PCA, Neural Networks etc. In this paper, a novel and efficient algorithm is proposed using Active Pixels which capture the essential local information of the facial image. The brody transform makes the approach more robust to rotational, translational invariance’s. The experiments were conducted on standard face recognition databases like FGNET age dataset and color FERET dataset, Texas 3D Face Recognition Database (Texas 3DFRD). The results demonstrated that our approach reduced memory requirement by 80% and the computational time by 70% in comparison with LBP approach while yielding same or even better recognition accuracy.
