Time-sequential Pipelined Imaging with Wavefront Coding and Super Resolution [PDF]
, 2017 Wavefront coding has long offered the prospect of mitigating optical aberrations and extended depth of field, but image quality and noise performance are inevitably reduced. We report on progress in the use of agile encoding and pipelined fusion of image

A more effective CT synthesizer using transformers for cone-beam CT-guided adaptive radiotherapy
Frontiers in Oncology, 2022 PurposeThe challenge of cone-beam computed tomography (CBCT) is its low image quality, which limits its application for adaptive radiotherapy (ART). Despite recent substantial improvement in CBCT imaging using the deep learning method, the image quality ...

Boosting in image quality assessment [PDF]
2016 IEEE 18th International Workshop on Multimedia Signal Processing (MMSP), 2016 In this paper, we analyze the effect of boosting in image quality assessment through multi-method fusion. Existing multi-method studies focus on proposing a single quality estimator. On the contrary, we investigate the generalizability of multi-method fusion as a framework.

The Use of Datasets of Bad Quality Images to Define Fundus Image Quality [PDF]
2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022 Screening programs for sight-threatening diseases rely on the grading of a large number of digital retinal images. As automatic image grading technology evolves, there emerges a need to provide a rigorous definition of image quality with reference to the grading task.
