Module Documentation

This class first copies the given input image into an OpenGL texture, then applies OpenGL-ES vertex and fragment shaders to achieve some image processing, and finally gets the resulting pixels back into an image.

This code is inspired somewhat from the tutorial and code examples found on this page:

But an important distinction is that we render to a framebuffer with an RGB565 renderbuffer attached, which accelerates processing and transfer of the results a lot.

Dewarp algorithm contributed by JeVois user Ali AlSaibie. It is to be used with a modified JeVois camera sensor that has a wide-angle lens. See for details.
