Snapshot Ptychography on Array cameras
Chengyu Wang, Minghao Hu, Yuzuru Takashima +2
We use convolutional neural networks to recover images optically down-sampled by using coherent aperture synthesis over a 16 camera array. Where conventional ptychograp…
Multiscale Phase Retrieval
David J. Brady, Timothy J. Schulz, Chengyu Wang
While characterization of coherent wavefields is essential to laser, x-ray and electron imaging, sensors measure the squared magnitude of the field, rather than the field itself. H…
Intelligent Autofocus
Chengyu Wang, Qian Huang, Ming Cheng +2
We demonstrate that deep learning methods can determine the best focus position from 1-2 image samples, enabling 5-10x faster focus than traditional search-based methods. In contra…
Smart Cameras
David J. Brady, Minghao Hu, Chengyu Wang +6
We review camera architecture in the age of artificial intelligence. Modern cameras use physical components and software to capture, compress and display image data. Over the past…
