I need help with optimization of a basic sharpening algorithm

[F53]

Im going to leave this topic now, but Ill leave anyone in the future who needs this what I did find:

1. rufsketch1’s link goes in detail how shaders work in proccesing 3

@rufsketch1

For realtime performance, you’ll need to do this in a shader . That way, instead of looping through every pixel one at a time, the GPU can run the filter on every pixel simultaneously.

2. a sharpening filter developed for an older version of proccesing
   Processing-Shader-Examples/sharpen_shader at master · atduskgreg/Processing-Shader-Examples · GitHub
3. another sharpening filter developed for an older version of processing
   GitHub - couleurs/glsl-sharpen: GLSL module for image sharpening

hopefully this helps in the future
