Analytics in real time surveillance video using two-bit transform accelerative regressive frame check

Abstract

Face recognition is an established area of research in computer vision and it had played a great role in developing content based personal retrieval systems from real time surveillance video feeds. Face recognition in live videos is a complex problem as facial features fall into high dimensional space and involves large search time. Though, there is an extensive improvement in computational infrastructure over the years, the need for improved search algorithms without increase in cost is a challenge. Existingmethodologies in literature fail to perform in real time scenarios as the cost of feature matching is high. Hence, this research work proposes a Two-Bit Transform AccelerativeRegressive Frame Check algorithm (2BT-ARFCA) methodology that facilitates face recognition in video at a faster rate, suitable for surveillance and authentication applications. Finally the results are experimentally validated with variousvideo datasets and the state-of-the-art techniques proves that the proposed method performs better in terms of Specificity, Sensitivity, Mean Square Error (MSE), Peak signal to noise Ratio (PSNR), The Structural Similarity Index (SSIM) and accuracy.
