Dictionary learning noise
WebMar 1, 2024 · We propose the sparse dictionary learning algorithm to denoise seismic data. • The sparse dictionary can adapt to the complexity of the input seismic data. • We propose an accelerated scheme to make the processing much faster. • The overall efficiency of the dictionary learning method is much improved. Abstract WebThe SR algorithm based on dictionary learning utilizes the characteristic that the natural images have a sparse representation under a specific dictionary, and applies the dictionary learning method to construct the dictionaries which can represent image patches sparsely, and then some additional information can be obtained to improve the ...
