Face recognition in very low bit rate SPIHT compressed facial images

Abstract

Biometric authentication procedures use facial images for authentication in an organization. Storing of large facial images require large storage space. To reduce the storage space, compression methods are employed. JPEG and JPEG2000 compression standards are recommended by ISO standard for facial recognition format up to the file size of 12 kB. In this paper we propose a scheme to evaluate the facial recognition performance of the very low bit rate facial images. The facial images are compressed using SPIHT encoding. The proposed scheme makes use of PCA and ICA methods to evaluate the results obtained. The very low bit rate facial images perform equivalent to the higher bit rate images in facial recognition.... © 2013 Springer International Publishing.
