Low-Latency and Scene-Robust Optical Flow Stream and Angular Velocity Estimation

open access: yesIEEE Access, 2021
Event cameras are bio-inspired sensors that capture intensity changes of pixels individually, and generate asynchronous and independent “events”.

INTUITIVE ESTIMATION OF SPEED USING MOTION AND MONOCULAR DEPTH INFORMATION

open access: yesStudia Universitatis Babes-Bolyai: Series Informatica, 2020
Advances in deep learning make monocular vision approaches attractive for the autonomous driving domain. This work investigates a method for estimating the speed of the ego-vehicle using state-of-the-art deep neural network based optical flow and single-

Direct Optical-Flow-Aware Computational Framework for 3D Reconstruction

open access: yesIEEE Access, 2019
In this paper, a direct computational method is presented which combines optical flow and structure from motion (SfM) by putting the SfM problem in the framework of optical flow estimation. In other word, the optical flow is reparametrized in term of the

Optical Flow Estimation Based on Curvelet Transform and Spatio-temporal Derivatives [PDF]

open access: yesEngineering and Technology Journal, 2010
Optical flow estimation is still one of the key problems in computer vision.When estimating the displacement field between two images, it is applied as soonas correspondences between pixels are needed.

Secrets of optical flow estimation and their principles [PDF]

open access: yes2010 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2010
The accuracy of optical flow estimation algorithms has been improving steadily as evidenced by results on the Middlebury optical flow benchmark. The typical formulation, however, has changed little since the work of Horn and Schunck. We attempt to uncover what has made recent advances possible through a thorough analysis of how the objective function ...

Dynamically consistent optical flow estimation [PDF]

open access: yes2007 IEEE 11th International Conference on Computer Vision, 2007
In this paper, we present a framework for dynamic consistent estimation of dense motion fields over a sequence of images. The originality of the approach is to exploit recipes related to optimal control theory. This setup allows performing the estimation of an unknown state function according to a given dynamical model and to noisy and incomplete ...

Optical Flow Estimation with Channel Constancy [PDF]

open access: yes, 2014
Large motions remain a challenge for current optical flow algorithms. Traditionally, large motions are addressed using multi-resolution representations like Gaussian pyramids. To deal with large displacements, many pyramid levels are needed and, if an object is small, it may be invisible at the highest levels.

A Robust and Discontinuity-Preserving Approach to Optical Flow Estimation

open access: yes, 2009
In this paper we develop a robust and discontinuity-preserving approach based on local and global combined model for the optical flow estimation. Firstly, the local and global optical flow methods are combined to yield dense flow fields that are robust ...

FGBRSN: Flow-Guided Gated Bi-Directional Recurrent Separated Network for Video Super-Resolution

open access: yesIEEE Access, 2023
Video Super-Resolution (VSR) is the task of reconstructing high-resolution (HR) video sequences from low-resolution (LR) video sequences. Apart from spatial information of reference frames, temporal information of neighboring frames is also important for
