The motivation of this project is to overcome the spatiotemporal tradeoffs of modern cameras. Data is redundant. This is a ubiquitous phenomenon people have witnessed. On the other hand, sampling a full resolution image (with redundancy) takes longer time than sampling fewer pixels for a camera. Thus, a natural question is if we can save spatial resolution for higher imaging speed.
My most recent project works on 4D imaging. That’s to compress both spatial and temporal information into a single image.
