Image fusion with nonsubsampled contourlet transform and sparse representation [PDF]
Journal of Electronic Imaging, 2013 Image fusion combines several images of the same scene into a fused image, which contains all important information. Multiscale transform and sparse representation can solve this problem effectively. However, due to the limited number of dictionary atoms, it is difficult to provide an accurate description for image details in the sparse representation ...

Computational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022 The incidence rate of peptic ulcer is increasing gradually. Medical images can meet the needs of patients as an auxiliary diagnosis and treatment method for peptic ulcer. However, in the long‐term treatment, the actual effect is average, and the diagnosis effect of gastrointestinal diseases will gradually deteriorate.
