Accuracy and Speed Improvement of Event Camera Motion Estimation Using a Bird’s-Eye View Transformation [PDF]
Sensors, 2022 Event cameras are bio-inspired sensors that have a high dynamic range and temporal resolution. This property enables motion estimation from textures with repeating patterns, which is difficult to achieve with RGB cameras.

Bayesian Estimation of Turbulent Motion [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2013 Based on physical laws describing the multiscale structure of turbulent flows, this paper proposes a regularizer for fluid motion estimation from an image sequence. Regularization is achieved by imposing some scale invariance property between histograms of motion increments computed at different scales.

Motion Estimation from Spheres [PDF]
2006 IEEE Computer Society Conference on Computer Vision and Pattern Recognition - Volume 1 (CVPR'06), 2006 This paper addresses the problem of recovering epipolar geometry from spheres. Previous works have exploited epipolar tangencies induced by frontier points on the spheres for motion recovery. It will be shown in this paper that besides epipolar tangencies, N^2 point features can be extracted from the apparent contours of the N spheres whenN \gt 2.

A Novel Parallel Motion Estimation Design and Implementation on GPU
IEEE Access, 2019 The development of high-resolution video mounts a serious challenge to the previous video coding standard. The appearance of the new generation standards greatly relieves the dilemma but increases the coding complexity dramatically.
