This paper describes OpenOpticalFlow, an open source optical flow program in Matlab for extraction of high-resolution velocity fields from various flow visualization images. This program is a useful ...

The three elements of optical flow are as follows: optical flow produces velocity field; it is a carrier with information and optical properties such as pixels; it is a projection imaging of 3D scene ...

uint64_t time_usec; /*< [us] Timestamp (UNIX Epoch time or time since system boot). The receiving end can infer timestamp format (since 1.1.1970 or since system boot) by checking for the magnitude of ...

To address these challenges, Stream-Flow is proposed to integrate optical flow information and enhance real-time object detection in UAV videos. StreamFlow incorporates Flow-Guided Dynamic Prediction ...

In this paper, we have proposed more robust and faster visual tracking framework using scale invariant feature transform (SIFT) and the optical flow in belief propagation (BF) algorithm for efficient ...

Optical illusion personality tests are strange ... the test claims to reveal if they are more organized or go with the flow. To take the test, simply look at the image and see what you saw at ...

Intra-aneurysmal flow changes, including mean aneurysm flow amplitude ratio (R), were subsequently assessed by the optical flow method, measuring the detector velocity field before and after device ...

This study investigated the vascular flow density in pathologically myopic eyes with optical coherence tomography angiography. This study was limited by its cross-sectional design, single-centre and ...
