Abstract

In this paper, we present a mobile face verification framework for automated attendance monitoring as a solution for more efficient, portable and cost-effective attendance monitoring systems. We use Raspberry Pi as mobile embedded input module connecting the webcam and radio frequency identification (RFID) reader to the personal computer (PC) which provides mobility due to its light weight and wireless connectivity. In order to increase the reliability of the system, we incorporate a face verification method which employs locally-normalized Gabor Wavelets as the features for dual verification stage. We evaluate the accuracy and processing time of the proposed face verification. It found that it produces good accuracy under limited reference sample constraint and fast response for small number of gallery images. The proposed method delivers 97%, 99.8% and 95.3% accuracy for AR, YALE B and FERET datasets. In term of processing speed, the proposed method managed to classify a single image against 500 gallery images in 1.909 seconds. The system delivers fast verification with high accuracy under the constraint of just single reference sample, which increases the reliability of the proposed system.
