How can I re-track an object if track(using optical flow) lost?
Hi,
What are the best approach/algorithm to re-track an object if track lost while tracking using dense optical flow? Here, both background and foreground is dynamic. ROI of Detected box of object is changing at different part of body of object just because of optical flow method. Note : Motion of the object is non-linear.
Can somebody suggest the good approach to handle this case. Thanks in advance. :)
In neural networks this is usually done by using a lstm layer.
imho, you have to explain, how do you track an "object" at all, using optflow. ?
@holger Thanks for your response. In my case there is no neural network , only Image processing concept .
@berak It's detection per frame using LK-optical flow. So there in some cases I'm loosing detection like corner case , sudden stop case,turning case,etc. How can I deal this?
Use a neural network with lstm XDDDDD. OR.... I know that opencv has a tracker api - you can use this if the images are coming in frame by frame. I am not sure but i think i read somewhere that some classes of tracking api of opencv also uses some kind of neural network- but i am not sure about this - is also not important.
Try read some tutorials about opencv tracking api.
