Filterio

A simple macOS image processing application using filters built with metal shaders

Implemented Filters

• Brightness
• Contrast
• Gamma
• Vignette
• Saturation
• RGB to GBR
• Pixelate

Each filter is implemented as a compute kernel which performs parallel computations on a given image. Each thread of the gpu performs its shader's calculation on an individual point of the input image

Todos

• Implement support for applying mulitiple filters at once
• Add ability to upload an image
• Add better support for rezing / resampling image as window size changes
