Weighted Performance comparison of DWT and LWT with PCA for Face Image Retrieval
This paper compares the performance of face image retrieval system based on discrete wavelet transforms and Lifting wavelet transforms with principal component analysis (PCA). These techniques are implemented and their performances are investigated using frontal facial images from the ORL database. The Discrete Wavelet Transform is effective in representing image features and is suitable in Fac...
متن کاملPerformance Evaluation of Face Recognition using PCA and N-PCA
Face recognition has become a valuable and routine forensic tool used by criminal investigators. It is an important area of computer vision research and has gained significant interest in recent years. Efforts in improving security, such as automatic surveillance and the use of biometrics in identification, are partly responsible for this increased interest. However, several challenges remain i...
متن کاملPerformance Evaluation of Face Recognition Using Pca
The face recognition problem is difficult by the great change in facial expression, head rotation and tilt, lighting intensity and angle, aging, partial occlusion (e.g. Wearing Hats, scarves, glasses etc.), etc. The Eigenfaces algorithm has long been a mainstay in the field of face recognition and the face space has high dimension. Principal components from the face space are used for face reco...
متن کاملPerformance Analysis of Pca Based Techniques for Face Authentication
Accurate authentication is of major concern in real time applications such as an automatic authentication system in any organization. Even though there are many approaches for face recognition in the literature, no algorithm was analyzed with respect to authentication applications. In this paper, we have discussed PCA based approaches Kernel-PCA, Gabor PCA, Phase congruency PCA, Phase congruenc...
متن کاملLda with Subgroup Pca Method for Facial Image Retrieval
We need to capture properties of face image variations from training persons and generalize them to a new test person for robust image retrieval, which is essential for the case that there is only a single image of the test person to retrieval face images of the equal person from database. Conventional methods of Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) can be e...
