Abstract
Abstract -This paper introduces a system in which the face recognition is carried out with the help of the local feature descriptors under the varying illumination conditions. As today face recognition is a very active area of research, a system which carries out the robust face recognition is needed to be developed. Face recognition is used in various fields of security and access control, surveillance military etc.
Local directional number pattern (LDN) is the descriptor which is used here to extract the features from the face image. The LDN code is computed by convolving the original image with the mask to extract the edge response images, from this images the most positive and most negative directions are taken to encode the information. The six bit binary code is then generated to give an LDN image. The face image is then divided into several regions and then for each region LDN is computed and the histogram of each region is taken. Then all the histograms are concatenated to form a feature vector.
Here the parameter used for evaluating the performance of the proposed system is recognition rate. This can be defined as number of person identified correctly divided by total number of persons in the test database. Number of experiments is carried out using different database-PIE, YALE, ORL. Numbers of face images from the original database are divided into training and test database. For the experiments carried so for, the recognition rates obtained for these masks are more than 70%. It is expected that the results may further improved by dividing the LDN image into more number of sections.
Keywords- Keywords- Face recognition, LDN (Local Directional Number Pattern), feature extraction, FRM (Face recognition method).
