With traditional imaging, it is difficult to resolve blurred image areas. The plenoptic camera overcomes this limitation by the aid of a micro lens array and an ...

2019年10月4日 — Decode a set of focused transmit ultrasound beams into the complete data set, indexed by individual transmit elements and receive channels.

由 OMH Rindal 著作 · 2022 · 被引用 1 次 — We compare the resulting b-mode images and coherence obtained from RTB, REFoCUS and conventional scanline beamforming and demonstrate that REFoCUS and RTB have ...

由 P Sakurikar 著作 · 2018 · 被引用 12 次 — We introduce RefocusGAN, a deblur- then-reblur approach to single image refocusing. We train conditional adversarial networks for deblurring and refocusing ...

由 SK Mohammed 著作 · 2017 · 被引用 38 次 — Abstract. This paper proposes a quality assessment of focusing criteria for imaging in digital off-axis holography. In the literature, several refocus ...
