Research Directions:

1) Object recognition  We focus on proposing more robust and effective image representations for image representation.

Laplacian sparse coding: We leverage the dependency among the local features for better sparse representation. [link]
Kernel sparse representation: Nonlinearity structure of the local features are considered sparse representation in Reproducing Kernel Hilbert Space [link]
Multi-Layer group sparse coding: Image tagging and classifications are jointly conducted in multi-layer group sparse coding framework.[link]
Category-Specific and Shared Dictionary Learning: A novel dictionary learning algorithm is proposed to exploit the commonality and Specificity among different object categories for better object representation. [link]


2)  Face recognition
Single Sample per Person Face Recognition: We proposed Regularized patch-based Representation for Single Sample Per Person Face Recognition. Such algorithm inherits the advantages of both holistic face representation and patch-based Face Representation.[link]
Image Set based Face Recognition: A patch-based sparse representation is posed for alignment-free image set classification. [link]

3)Deep leaning algorithm

DEFEATnet: We use sparse coding as the basic building block to build the deep neural network for better image representation. [link]
PCAnet: We use the simplest PCA as the components to build deep structure. Such framework achieves the best performance on the FERET dataset. [link]
