Javascript Optical Flow Implementation

Question

I'm looking for an optical flow implementation to run on my web app in html5 canvas, but didn't found something immediately usable. If I choose to implement it by myself, is it be possible to achieve (near) real-time performance?

Or, since in the current setting, I actually just want to know the main optical flow is moving to the left or right, are there some easier algorithms I can use?

I made this little library which does (I hope) exactly what you are asking for.

A demo Which utilizes this library to control the ball by moving your hands.

I made a real time feature tracking that can generate sparse optical flow and point trajectories. It uses asm.js, so it runs faster on firefox (50ms per 320x240 frame - 1500 points)
