Supervised Deep Sparse Coding Networks
Xiaoxia Sun, Nasser M. Nasrabadi, Trac D. Tran
In this paper, we describe the deep sparse coding network (SCN), a novel deep network that encodes intermediate representations with nonnegative sparse coding. The SCN is built upo…
Sparse Coding with Fast Image Alignment via Large Displacement Optical Flow
Xiaoxia Sun, Nasser M. Nasrabadi, Trac D. Tran
Sparse representation-based classifiers have shown outstanding accuracy and robustness in image classification tasks even with the presence of intense noise and occlusion. However,…
Unsupervised domain adaption dictionary learning for visual recognition
Zhun Zhong, Zongmin Li, Runlin Li +1
Over the last years, dictionary learning method has been extensively applied to deal with various computer vision recognition applications, and produced state-of-the-art results. H…
Task-Driven Dictionary Learning for Hyperspectral Image Classification with Structured Sparsity Constraints
Xiaoxia Sun, Nasser M. Nasrabadi, Trac D. Tran
Sparse representation models a signal as a linear combination of a small number of dictionary atoms. As a generative model, it requires the dictionary to be highly redundant in ord…
Structured Priors for Sparse-Representation-Based Hyperspectral Image Classification
Xiaoxia Sun, Qing Qu, Nasser M. Nasrabadi +1
Pixel-wise classification, where each pixel is assigned to a predefined class, is one of the most important procedures in hyperspectral image (HSI) analysis. By representing a test…
