Adaptive Fractional-Order Multi-Scale Optimization TV-L1 Optical Flow Algorithm

Fractal and Fractional
We propose an adaptive fractional multi-scale optimization optical flow algorithm, which for the first time improves the over-smoothing of optical flow estimation under the total variation model from the perspective of global feature and local texture ...

PWC-Net: CNNs for Optical Flow Using Pyramid, Warping, and Cost Volume

, 2018
We present a compact but effective CNN model for optical flow, called PWC-Net. PWC-Net has been designed according to simple and well-established principles: pyramidal processing, warping, and the use of a cost volume. Cast in a learnable feature pyramid,

Aero-optical characterization of aircraft optical turrets by holography, interferometry and shadowgraph [PDF]

, 1980
Density variations in the aircraft boundary layer, turret wakes and shock waves create distortion of an optical wavefront through associated refractive index variations. Such effects can be observed directly through optical flow visualization.

On discontinuous optical flow

Comput. Artif. Intell., 2012
This paper deals with an analysis of image motion in frequency space with respect to motion discontinuities and surface translucence. The frequency structure of motion discontinuities due to occlusion is derived under models of constant and linear optical flow. Authors demonstrate its various geometrical properties.

Flow and critical velocity of an imbalanced Fermi gas through an optical potential

, 2007
Optical lattices offer the possibility to investigate the superfluid properties of both Bose condensates and Fermionic superfluid gases. When a population imbalance is present in a Fermi mixture, this leads to frustration of the pairing, and the ...

Amodal Optical Flow

2024 IEEE International Conference on Robotics and Automation (ICRA)
Optical flow estimation is very challenging in situations with transparent or occluded objects. In this work, we address these challenges at the task level by introducing Amodal Optical Flow, which integrates optical flow with amodal perception. Instead of only representing the visible regions, we define amodal optical flow as a multi-layered pixel ...
