Hi ImageAnalyst

I'm aware that there are algorithms for detecting optic flow and the focus of expansion, but I'm not aware of how to actually do it. Do you have any suggestions or particular methods you find to work the best? Also, if I am able to detect optic flow, how would I then detect lateral motion? Since movement is a combination of lateral movements and forward/backwards motion most of the time, I'd like to calculate optic flow and then somehow calculate lateral motion as well.

Thanks for the response!

best,

Don
