I need a processing coder

I am working on a project that requires a bit of generative coding on processing. The code will be able to generate an animated gradient visual based on the prominent colors in the input image. In short, I need a code that is able to generate an animated gradient visual that runs endlessly with an image. I will then map this visual on a LED panel using OPC + fadecandy. The photos are the kind of result that I want to achieve.
