Spaceborne SAR Imaging Algorithm for Coherence Optimized. [PDF]
PLoS ONE, 2016 This paper proposes SAR imaging algorithm with largest coherence based on the existing SAR imaging algorithm. The basic idea of SAR imaging algorithm in imaging processing is that output signal can have maximum signal-to-noise ratio (SNR) by using the ...

On the selection of image compression algorithms [PDF]
Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002 This paper attempts to give a recipe for selecting one of the popular image compression algorithms based on: 1) wavelet, 2) JPEG/DCT, 3) vector quantisation, and 4) fractal approaches. We review and discuss the advantages and disadvantages of these algorithms for compressing gray-scale images, give an experimental comparison on four 256/spl times/256 ...

Monopulse forward-looking imaging algorithm based on Levenberg–Marquardt optimisation
The Journal of Engineering, 2019 With precise angle measurement, traditional monopulse techniques for forward-looking imaging can acquire exact angle information of one single target within a radar beam. However, when multiple targets exist in a beam, it is difficult to resolve them. To

Imaging of the spleen: a proposed algorithm [PDF]
American Journal of Roentgenology, 1980 The /sup 99m/Tc sulfur colloid scan is an effective initial method for evaluating splenic size, position, and focal or diffusely altered radionuclide uptake. Sonography is a useful next step in determining whether focal lesions are solid or cystic and the relation of the spleen to adjacent organs.

International Journal of Antennas and Propagation, 2021 With the rapid development of materials science and medical imaging technology, traditional optimization algorithms cannot solve the problem of inverse scattering of complex scatterers well. Therefore, more and more imaging algorithms for solving complex
