Sentence examples for is sparsity from inspiring English sources

One such model, which has become an important prior for many signal processing tasks ranging from denoising and compressed sensing to super resolution, inpainting and classification, is sparsity in a dictionary [1 8].

A better assumption in the frequency domain is to have random sparsity [25 27] as shown in row 5 and column 3. A generalization of the sparsity in the frequency domain is sparsity in any transform domain such as Discrete Cosine and Wavelet Transforms (DCT and DWT); this concept is further generalized in CS (row 6) where sampling is taken by a linear combination of time domain samples [2, 28 30].

A fundamental question, i.e. "Is sparsity based reconstruction of SDOCT images beneficial as compared to alternative modern adaptive restoration/reconstruction techniques?" has yet to be answered.

The TSSG-KF tracker implemented by (8) to (10) is sparsity-agnostic, as it does not explicitly utilize the prior knowledge that x k is sparse.

All of the methods are sparsity-driven.

IAA, SLIM, and SPICE algorithms [12] are sparsity-based techniques that can estimate the DOA depending on a few snapshots with high resolution and low sidelobes.

Both L1LOG and L1LOG-C are sparsity-induced methods, but the number of common features between the two methods was very limited.

DCS uses the concept of joint sparsity, which is the sparsity of every signal in the ensemble.

The dual of frequency-sparsity is time-sparsity, which can happen in a burst or a random fashion.

β is the sparsity index that measures the sparsity of v and is in the range of 0 ≤ β ≤ 1.

where the scalar s is the sparsity of vector e.
