Abstract

For the purpose of efficient observation and monitoring in information security, the input image is required to be transferred from one place to another for decision making (higher administration). In this paper, the hybrid k-PCA method is used for efficient compression. However, some pixels in the input image may be missed or distorted during the transmission process. Therefore, Hopfield neural networks are used for retrieving the original of distorted images. Then fast feedforward neural networks (FFNNs) are applied for face detection in the received image. The speed of these neural networks is accelerated by modifying its algorithm. This is done by applying cross correlation in the frequency domain between the received image and the weights of neural networks. The result of cross correlation implemented in the frequency domain is the same as that one obtained in time domain. Moreover, the speed of operation is faster than performing cross correlation in time domain. It is proved mathematically and practically that the proposed algorithm is fast and efficient in retrieving missed pixels in distorted images.
