Hi, I'm new to OpenCV and image processing. My objective is to detect obstacles via an android phone, the user carries the phone with him.
I have used canny edge detection(which worked) and tried background subtraction(which didn't work) and am at a loss on what to do next. I need to detect an incoming object. What should I do next to detect an obstacle?
Any help would be much appreciated.

Detecting random objects, of any color, size or texture on a mobile phone is a task that haven't been solved yet. Focus on a much, much smaller scale: Define some objects to be avoided (let's say red or blue squares) and start from there. When you are ready with them, try to generalize a bit, and so on.

If you are ready to use multiple frames, you could use Optical flow to detect if any object is coming towards the user.

@jayrambhia Can you elaborate on how to achieve this with optical flow please?
