Heuristic mismatch explanation for BM3D-AMP-MRI's poor MRI recovery
Heuristic mismatch conjecture. BM3D-AMP-MRI's significantly worse NMSE is caused by its heuristic modification and the mismatch between Cartesian-masked an…

Conjecture on the robust range of the sampling parameter
Let be the parameter varied in the mixed-probability-density-function experiments, and let RSNR denote the reconstruction signal-to-noise ratio. Robust- conjecture. We conje…

Conjecture that low RSNR explains the absence of observed patterns
Let RSNR denote the reconstruction signal-to-noise ratio in the tested MRI reconstructions. The low-RSNR cases are the cases whose reconstructions have relatively low RSNR. Low-RSN…

Conjecture that image texture determines reconstruction performance
The image texture refers to the visual structure and complexity of an image, and each algorithm is an image-reconstruction algorithm whose performance can be evaluated on that imag…
