Abstract EN
Face Recognition (FR) under varying pose is challenging and exacting pose invariant features is an effective approach to solve this problem.
In this paper, we propose a novel Truncated Transform Domain Feature Extractor (TTDFE) to improve the performance of the FR system.
TTDFE involves a unique combination of Symlet - 4 DWT, 2D - DCT, followed by a novel truncation process.
The truncation process extracts higher amplitude coefficients from the Discrete Cosine Transform (DCT) matrix.
An optimal truncation point is estimated, which is inspired by a relationship developed between the image dimensions and the positions of DCT amplitude peaks.
TTDFE is used for efficient feature extraction and a Binary Particle Swarm Optimization - based feature selection algorithm is used to search the feature space for the optimal feature subset.
Experimental results, obtained by applying the proposed algorithm on 5 benchmark face databases with large pose variations, namely FERET, UMIST, FEI, PHPD and IFD, show that the proposed system outperforms other FR systems.
A significant increase in the Recognition Rate and a substantial reduction in the number of features selected, are observed.
