ld ask that gives the function IMAQ Optical flow(LK) or (HS) at the outputs of the Velocity 

Component 1 Out and Velocity Component 2 Out? And what do I get if append to them IMAQ ImageTo Array?

Hi Kvanto,

Could you please make a new forum post for this question and clarify it as well?  I'm not quite sure what you're asking.

Hello Kvanto !

     I'm intersting about the Optical Flow_for_video_grab,I download this vi ,unfortunately every time I run this vi there is an error:Incompatible image size.Can you tell me how to solve it?

[Kvanto]

Hello! Unfortunately, the method of optical flow I is not adapted to download the video. For it to work I used the convert video in a series of images.  Here is a good vi.

Hi, i'm new.

I would know 2 things:
-i've wired velocity component with ImageToArray and an array indicator but know in indicator i get the speed of movement?
-in LKP estimation, distance array indicate distance between feature points in and feature points out, but in which unit of measurement?

(sorry for my english)

Hi fra.bar,

This thread is several months old and probably isn't being monitored anymore.  Feel free to create a new thread and post your questions.
