"Webbmeasurements is comparable to the compressed size of the signal. Clearly, the measurements have to be suitably designed. It is a remarkable fact that all provably good measurement matrices designed so far are random matri-ces. It is for this reason that the theory of compressive sensing uses a lot of tools from probability theory. " - Shannon theory for compressed sensing

Webb8 sep. 2024 · Compression sensing is a new signal acquisition theory, which breaks through the limitation of Nyquist sampling theorem. The sampling frequency of compressed sensing signal is determined by the structure and content of the signal, and the coding and decoding frame of compressed sensing signal is asymmetric. WebbA central challenge in scanning transmission electron microscopy (STEM) is to reduce the electron radiation dosage required for accurate imaging of 3D biological nano-structures. Methods that permit tomographic reconstruction from a reduced number of STEM acquisitions without introducing significant degradation in the final volume are thus of …
