Random projection-based partial feature extraction for robust face recognition
In this paper, a novel feature extraction method for robust face recognition (FR) is proposed. The proposed method combines a simple yet effective dimensionality increasing (DI) method with an information-preserving dimensionality reduction (DR) method. For the proposed DI method, we employ the rectangle filters which sum the pixel values within a randomized rectangle window on the face image t...
متن کاملGamma Correction Technique Based Feature Extraction for Face Recognition System
One of the most important challenges for practical face recognition systems is to make recognition more reliable under uncontrolled lighting conditions. We tackle this by using novel illumination-insensitive preprocessing method. The proposed face recognition system consists of a gamma correction, a preprocessing stage, a hybrid Fourier-based facial feature extraction, and Principal Component L...
متن کاملHybrid Feature Extraction Method for Partial Face Recognition
Face Recognition is one of the challenging tasks faced till date in the field of computer vision and pattern recognition. A robust face recognition system is essential for proper and accurate face recognition. Facial feature extraction is an important stage of face recognition process as it includes the important information required for face recognition. A good feature extraction algorithm hel...
متن کاملSVM-based feature extraction for face recognition
The primary goal of linear discriminant analysis (LDA) in face feature extraction is to find an effective subspace for identity discrimination. The introduction of kernel trick has extended the LDA to nonlinear decision hypersurface. However, there remained inherent limitations for the nonlinear LDA to deal with physical applications under complex environmental factors. These limitations includ...
متن کاملFace Recognition by Curvelet Based Feature Extraction
This paper proposes a new method for face recognition based on a multiresolution analysis tool called Digital Curvelet Transform. Multiresolution ideas notably the wavelet transform have been profusely employed for addressing the problem of face recognition. However, theoretical studies indicate, digital curvelet transform to be an even better method than wavelets. In this paper, the feature ex...
