Partial least squares for face hashing
Face identification is an important research topic due to areas such as its application to surveillance, forensics and human-computer interaction. In the past few years, a myriad of methods for face identification has been proposed in the literature, with just a few among them focusing on scalability. In this work, we propose a simple but efficient approach for scalable face identification base...
متن کاملClassification schemes based on Partial Least Squares for face identification
Approaches based on the construction of highly discriminative models, such as one-against-all classification schemes, have been employed successfully in face identification. However, their main drawback is the reduction in the scalability once the models for each individual depend on the remaining subjects. Therefore, when new subjects are enrolled, it is necessary to rebuild all models to take...
متن کاملPartial Least Squares for Discrimination
Partial least squares (PLS) was not originally designed as a tool for statistical discrimination. In spite of this, applied scientists routinely use PLS for classification and there is substantial empirical evidence to suggest that it performs well in that role. The interesting question is: why can a procedure that is principally designed for overdetermined regression problems locate and emphas...
متن کاملThermal-to-visible face recognition using partial least squares.
Although visible face recognition has been an active area of research for several decades, cross-modal face recognition has only been explored by the biometrics community relatively recently. Thermal-to-visible face recognition is one of the most difficult cross-modal face recognition challenges, because of the difference in phenomenology between the thermal and visible imaging modalities. We a...
متن کاملHyperspectral Face Recognition using 3D-DCT and Partial Least Squares
Hyperspectral imaging offers new opportunities for inter-person facial discrimination. However, due to the high dimensionality of hyperspectral data, discriminative feature extraction for face recognition is more challenging than 2D images. For dimensionality reduction and feature extraction most of the previous approaches just sub sampled the hyperspectral data [5, 6, 9] or used simple PCA [3]...
