Modified Local Binary Pattern Algorithm for Feature Dimensionality Reduction.
A face recognition algorithm with feature dimensionality reduction is proposed. The proposed algorithm is based on a variant of Local Binary Pattern (LBP) for face detection and recognition. The features of each block of face image is extracted and then global feature of face is constructed from super histogram. For recognition, traditional methods are used. The query image is compared with the dataset (ORL Dataset, LFW Dataset and Yale Dataset) in similarity index and the minimum distance. The maximum similarity is used to define as the class of query image. The reduction in number of features is achieved by modifying the traditional LBP process. The proposed modified method is observed as more fast and efficient for face recognition as compared to the existing algorithms.
