Dictionary Learning with Spatio-spectral Sparsity Constraints
Devising efficient sparse decomposition algorithms in large redundant dictionaries has attracted much attention recently. However, choosing the right dictionary for a given data set remains an issue. An interesting approach is to learn the best dictionary from the data itself. The purpose of this contribution is to describe a new dictionary learning algorithm for multichannel data analysis purp...
متن کاملShip Classification Based on MSHOG Feature and Task-Driven Dictionary Learning with Structured Incoherent Constraints in SAR Images
In this paper, we present a novel method for ship classification in synthetic aperture radar (SAR) images. The proposed method consists of feature extraction and classifier training. Inspired by SAR-HOG feature in automatic target recognition, we first design a novel feature named MSHOG by improving SAR-HOG, adapting it to ship classification, and employing manifold learning to achieve dimensio...
متن کاملStructured Dictionary Learning for Classification
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 fixed transformation or a signal dependent dictionary. To better capture the data characteristics, various dictionary learning methods have been proposed for both reconstruction and classification tasks. For classifi...
متن کاملTask-Driven Dictionary Learning for HyperspectralImage Classification with Structured SparsityConstraints Sparse representation models a signal as a linear combination of a small number of dictionary
Task-Driven Dictionary Learning for HyperspectralImage Classification with Structured SparsityConstraints Report Title 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 order to ensure both a stable high sparsity level and a low reconstruction error for the signal. Howe...
متن کاملDictionary Learning and Low-rank Sparse Matrix Decomposition for Sparsity-driven SAR Image Reconstruction
Synthetic aperture radar (SAR) is one of the most widely used remote sensing modalities, providing images for a variety of applications including those in defense, environmental science, and weather forecasting. However, conventionally formed SAR imagery from undersampled observed data, arising in several emerging applications and sensing scenarios, suffers from artifacts that might limit effec...
