Discriminative models for robust image classification
Umamahesh Srinivas
A variety of real-world tasks involve the classification of images into pre-determined categories. Designing image classification algorithms that exhibit robustness to acquisition…
Multi-task Image Classification via Collaborative, Hierarchical Spike-and-Slab Priors
Hojjat Seyed Mousavi, Umamahesh Srinivas, Vishal Monga +3
Promising results have been achieved in image classification problems by exploiting the discriminative power of sparse representations for classification (SRC). Recently, it has be…
Structured Dictionary Learning for Classification
Yuanming Suo, Minh Dao, Umamahesh Srinivas +2
Sparsity driven signal processing has gained tremendous popularity in the last decade. At its core, the assumption is that the signal of interest is sparse with respect to either a…
Discriminative Local Sparse Representations for Robust Face Recognition
Yi Chen, Umamahesh Srinivas, Thong T. Do +2
A key recent advance in face recognition models a test face image as a sparse linear combination of a set of training face images. The resulting sparse representations have been sh…
