Well, I'm still new to piv, and I've tried to replicate the results from the examples here, but when I try it out with my own pictures, there seems to be a bit of a problem.
After analysing, the entire (and I do mean ENTIRE) picture is filled with the green vector arrows, and I lots of them do not correspond to the particles to be tracked.
How do I go about fixing this issue?
Help is greatly appreciated!!
just by looking at the images (no matlab available at the moment), I can tell you that the delta t is much too high. You need to record the images with a higher frame rate (or slow down the velocity of the flow...)
