Face recognition presents a challenging problem in the field of image analysis and computer vision. It has received a great deal of attention over the last few years because of its many applications in various domains. Disk storage space is one of the most fundamental challenges in designing biometric system. Due to limited bandwidth and storage capacity, images must be compressed before storing and transmitting. In biometrics datasets, facial images are usually stored in JPEG compressed format and should be fully decompressed to be used in a face recognition system.
