Learning Robust And Discriminative Manifold Representations For Pattern Recognition, Sriram Kumar

Theses

Face and object recognition find applications in domains such as biometrics, surveillance and human computer interaction. An important component in any recognition pipeline is to learn pertinent image representations that will help the system to discriminate one image class from another. These representations enable the system to learn a discriminative function that can classify a wide range of images. In practical situations, the images acquired are often corrupted with occlusions and noise. Thus, a robust and discriminative learning is necessary for good classification performance.

This thesis explores two scenarios where robust and discriminative manifold representations help recognize face and object …
