I have an image with an animated image effect (a nice glitch effect) and would like to recreate the effect as a filter that can be applied to other images or videos using graphics libraries like [OpenCV](https://opencv.org/) instead of graphic programs.

On what Stack Exchange site should I ask?

I want to create the effect as code, so Stack Overflow comes to mind. But I do not need help creating the effect, I need help understanding the parts the effect is composed of (e.g. brightness change, pixelisation, etc.) and the order of these processing steps, so I need the help in the analysis and not for the program that should mimic the effect. In addition I am not sure how many people there are skilled in creating graphics (as in "applying a series of effects to an image to create the wanted appearance", not as in "programming an effect when I already know how it works").

Stack Exchange has some sites for computer artists, but I fear that the question may be too broad there and I am not sure if they can tell tell elements or just functions (e.g. in Photoshop) that execute a lot of different steps to create such an effect.

Is the question suitable for Stack Exchange at all?

I just asked on [Meta Graphic Design](https://graphicdesign.meta.stackexchange.com/q/3715/152935) but will keep this question open for more opinions on where I could get the best help.
