Description: This paper identifies a novel feature space to address the problem of human face recognition from still images. This based on the PCA space of the features extracted by a new multiresolution analysis tool called Fast Discrete Curvelet Transform. Curvelet Transform has better directional and edge representation abilities than widely used wavelet transform. Inspired by these attractive attributes of curvelets, we introduce the idea of decomposing images into its curvelet subbands and applying PCA (Principal Component Analysis) on the selected subbands in order to create a representative feature set. Experiments have been designed for both single and multiple training images per subject. A comparative study with wavelet-based and traditional PCA techniques is also presented. High accuracy rate achieved by the proposed method for two well-known databases indicates the potential of this curvelet based feature extraction method.-This paper identifies a novel feature space to address the problem of human face recognition from still images.

[VHDL-FPGA-VerilogTIMEFACEDETECTIONANDLIPFEATUREEXTRACTIONUSINGFPGA

Description: Abstract—This paper proposes a new technique for face detection and lip feature extraction. A real-time field-programmable gate array (FPGA) implementation of the two proposed techniques is also presented. Face detection is based on a naive Bayes classifier that classifies an edge-extracted representation of an image. Using edge representation significantly reduces the model’s size to only 5184 B, which is 2417 times smaller than a comparable statistical modeling technique, while achieving an 86.6 correct detection rate under various lighting conditions. Lip feature extraction uses the contrast around the lip contour to extract the height and width of the mouth, metrics that are useful for speech filtering. The proposed FPGA system occupies only 15 050 logic cells, or about six times less than a current comparable FPGA face detection system.-Abstract—This paper proposes a new technique for face detection and lip feature extraction.
