EDFLOW: Event Driven Optical Flow Camera With Keypoint Detection and Adaptive Block Matching
IEEE transactions on circuits and systems for video technology (Print), 2022 Event cameras such as the Dynamic Vision Sensor (DVS) are useful because of their low latency, sparse output, and high dynamic range. In this paper, we propose a DVS+FPGA camera platform and use it to demonstrate the hardware implementation of event ...

Temporal symmetry constraints in block matching [PDF]
2009 IEEE 13th International Symposium on Consumer Electronics, 2009 Video processing applications such as picture rate conversion depend on accurate and consistent motion estimation. Most motion estimation and optical flow algorithms use some form of spatial regularization to improve consistency, but few perform a temporal regularization based on the symmetry between successive vector fields.
