Optical flow object detection

Hi everyone,

I am new on OpenCV so I want to ask, can I use video from UAV and then use it with OpenCV for analyzing optical flow for detecting object?

can you explain, what your objects are, and why you think of using optical flow for this ?

(optical flow does not "detect" anything, it just gives you information about movement)

I will use the information for obstacle avoidance, but before implementing to the UAV for obstacle avoidance, I am just using optical flow for detect object in front of my UAV. So, can I use optical flow for that?

similar to this ?

yes similiar with that. Can you give me any tutorial links for using optical flow on open cv ?

Thanks for your information, I will try best for my final year project :)

Can I implemented optical flow with opencv on Raspberry pi 2 ?

anything on a raspi will be gross slow. (sure, go and try, though)

imho, sparse optical flow (lk) works ok in realtime, as long as you restrict / resize the images to like 320x240
