Eye-Strip based Person Identification based on Non-Subsampled Contourlet Transform

TL;DRAbstract

Many state-of-the-art face recognition systems fail to identify a person when most portions of the face are occluded. This paper addresses an intriguing problem of face recognition only with eye-strip samples as testing images and full images or again eye-strips as database images. Non-sub-sampled Contourlet transform is a distinguished algorithm for extracting soft and smooth contour-like edges without any loss of information. It also produces eminent features due to its localization and directionality preserving abilities and has strong resemblance with abilities of human visual cortex to extract features. This does not require any boosting of subband coefficients. We have proposed a novel approach that adds all the sub-bands at each pyramidal level of nonsubsampled contourlet transform to achieve a hybrid high frequency composite sub-band and minimize the dimensionality followed by feature extraction using Weber Local Descriptor (WLD) on the hybrid high frequency subband.
