Nettet8. apr. 2024 · Many sparse representations and dictionary learning-based SISR methods are reported in the literature [6, 9, 36, 40, 43].Yang et al. [] proposed a sparse coding-based SR method (ScSR) using a global dictionary learned from both LR and HR image patches.However, for remote-sensing images, the ScSR method is unable to recover … NettetIn this paper, we propose to jointly learn a discrimina-tive Bayesian dictionary with a linear classiﬁer in a fully supervised manner, using two coupled Beta-Bernoulli Pro-cesses [17]. To learn the dictionary, we use separate draws of a ﬁnite Beta-Bernoulli Process for each class but use the same base measure. To jointly learn the ...

Nettet11. nov. 2015 · We propose practical algorithms to implement joint sparse signal recovery and present its superiority over independent signal recovery. When signals are not sparse themselves, but can be jointly sparsely represented in some basis, we propose a joint dictionary learning algorithm that learns dictionaries in which the joint sparsity is … NettetWe adopt a mutual incoherence constrain for each sub-dictionary to encourage learned sub-dictionaries to be as independent as possible. A Fisher-like discriminative criterion is also introduced to coding vectors over all the class-specific sub-dictionaries, which can indirectly improve the discriminative ability of learned dictionary.
