What is measurement matrix in compressive sensing?

The measurement matrix is one of most essential parts in compressive sensing. For this application, the measurement matrix decides each time which part of the IR light will be reflected and finally reach the CNT detector. Correctly selected measurements will lead to fewer measurements and a clear reconstructed image.

What is matrix measurement?

In the measurement process, a measurement matrix is used to sample only the components that best represent the signal. The choice of the measurement matrix has an important impact on the accuracy and the processing time of the sparse recovery process.

How does compressed sensing work?

Compressed sensing addresses the issue of high scan time by enabling faster acquisition by measuring fewer Fourier coefficients. This produces a high-quality image with relatively lower scan time. Another application (also discussed ahead) is for CT reconstruction with fewer X-ray projections.
