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 ...

Particle Image Velocimetry (PIV) and optical flow methods are essential techniques used in fluid mechanics to measure and analyze the velocity fields of fluids. These methods involve capturing ...

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 ...
