Sparse representation of astronomical images [PDF]

open access: yesJournal of the Optical Society of America A, 2013
Sparse representation of astronomical images is discussed. It is shown that a significant gain in sparsity is achieved when particular mixed dictionaries are used for approximating these types of images with greedy selection strategies. Experiments are conducted to confirm: i)Effectiveness at producing sparse representations.

Explicit Object Representation by Sparse Neural Codes [PDF]

open access: yes, 2008
Neurons have been identified in the human medial temporal lobe (MTL) that display a strong selectivity for only a few stimuli (such as familiar individuals or landmark buildings) out of perhaps 100 presented to the test subject.

Bayesian Orthogonal Component Analysis for Sparse Representation [PDF]

open access: yes, 2010
This paper addresses the problem of identifying a lower dimensional space where observed data can be sparsely represented. This undercomplete dictionary learning task can be formulated as a blind separation problem of sparse sources linearly mixed with ...

Sparse representation of salient regions for no-reference image quality assessment

open access: yesInternational Journal of Advanced Robotic Systems, 2016
This paper introduces an efficient feature learning framework via sparse coding for no-reference image quality assessment. The important part of the proposed framework is based on sparse feature extraction from a sparse representation matrix, which is ...

A weighted block cooperative sparse representation algorithm based on visual saliency dictionary

open access: yesCAAI Transactions on Intelligence Technology, 2023
Unconstrained face images are interfered by many factors such as illumination, posture, expression, occlusion, age, accessories and so on, resulting in the randomness of the noise pollution implied in the original samples.
