iMAP Beamforming for High-Quality High Frame Rate Imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2019 We present a statistical interpretation of beamforming to overcome limitations of standard delay-and-sum (DAS) processing. Both the interference and the signal of interest are viewed as random variables and the distribution of the signal of interest is exploited to maximize the a-posteriori distribution of the aperture signals.

Bringing a Blurry Frame Alive at High Frame-Rate With an Event Camera [PDF]
2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019 Event-based cameras can measure intensity changes (called `{\it events}') with microsecond accuracy under high-speed motion and challenging lighting conditions. With the active pixel sensor (APS), the event camera allows simultaneous output of the intensity frames.

A Study of High Frame Rate Video Formats [PDF]
IEEE Transactions on Multimedia, 2019 High frame rates are acknowledged to increase the perceived quality of certain video content. However, the lack of high frame rate test content has previously restricted the scope of research in this area—especially in the context of immersive video formats. This problem has been addressed through the publication of a high frame rate video database BVI-

Frame-Event Alignment and Fusion Network for High Frame Rate Tracking
2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2023 Most existing RGB-based trackers target low frame rate benchmarks of around 30 frames per second. This setting restricts the tracker's functionality in the real world, especially for fast motion. Event-based cameras as bioinspired sensors provide considerable potential for high frame rate tracking due to their high temporal resolution.
