Here’s a little experiment showing how to build a cross-platform C++ OpenCV app that also works in the browser (via emscripten).
More details in my OpenCV Web Apps blog post.
Let’s make Sirocco, the real parrot, PARTY!
On the left, the original, a regular HTML5 video.
On the right, the same video being processed live, frame-by-frame cycling of the frame’s hue channel.
This is a live, real time view, running in the browser!
Use the slider to change the color cycle speed.
