A nonlinear approach for face sketch synthesis and recognition
TL;DR: This paper presents a face recognition system based on face sketches that is based on pseudo-sketch synthesis and sketch recognition, and experimental results show that the performance of the proposed method is encouraging.
Journal ArticleDOI
Implicit and explicit camera calibration: theory and experiments
Guo-Qing Wei,Songde Ma +1 more
TL;DR: Under the assumption of the radial distortion model, this paper presents a computationally efficient method for explicitly correcting the distortion of image coordinates in frame buffer without involving the computation of camera position and orientation.
Proceedings ArticleDOI
Solving the small sample size problem of LDA
TL;DR: This paper proposes a new method making use of the null space of S/sub w/ effectively and solve the small sample size problem of LDA, and compares its method with several well-known methods.
Journal ArticleDOI
Image annotation via graph learning
TL;DR: A Nearest Spanning Chain (NSC) method is proposed to construct the image-based graph, whose edge-weights are derived from the chain-wise statistical information instead of the traditional pairwise similarities.
Journal ArticleDOI
Improving kernel Fisher discriminant analysis for face recognition
TL;DR: A new kernel function, called the cosine kernel, is proposed to increase the discriminating capability of the original polynomial kernel function and a geometry-based feature vector selection scheme is adopted to reduce the computational complexity of KFDA.
