چکیده
This research presents an improved real-time face recognition system at a low resolution of 15 pixels with pose and emotion variations. We have designed our datasets named LRD200 LRD100, which been used for training classification. The detection part uses the Viola-Jones algorithm, receives image from to process it using Local Binary Pattern Histogram (LBPH) algorithm preprocessing contrast limited adaptive histogram equalization (CLAHE) alignment. database in this can be updated via custom-built standalone android app automatic restarting database. Using proposed accuracy 78.40% px 98.05% 45 achieved containing 200 images per person. With 100 person (LRD100) accuracies are 60.60% 95% respectively. A facial deflection about 30 degrees on either side front showed average precision 72.25% - 81.85%. employed law enforcement purposes, where surveillance camera captures low-resolution because distance camera. It also as airports, bus stations, etc., reduce risk possible criminal threats.

Local Binary Pattern based Resolution Variation Video-based Face Recognition
Video-based face recognition is a very challenging problem as there is a variation in resolution, illumination, pose, facial expressions and occlusion. In this paper, we have presented an approach for resolution variation video-based face recognition system using the combination of local binary pattern (LBP), principal component analysis (PCA) and feed forward neural network (FFNN). We used, st...

متن کاملFace Recognition using Local Ternary Pattern for Low Resolution Image
Face Recognition system is one of an effective system which is used for the identification of a person from a video frame or a digital image. The concept of FRS is primarily used in the field of security systems and hence can be get compared to other systems which are biometric in nature such as IRIS Recognition or Fingerprint systems. Apart from these techniques, Local Binary Patterns (LBP) al...
متن کاملFace Identification Based on Contrast Limited Adaptive Histogram Equalization (CLAHE)
This paper proposes a face identification method based on Contrast Limited Adaptive Histogram Equalization (CLAHE) robust to facial expressions, occlusion and specially to illumination changes. Based on Eigenphases algorithm for feature extraction, the Principal Components Analysis (PCA) and the Phase Spectrum was used as feature extraction stage, and Support Vector Machine (SVM) as a classifie...
