PerceptLUT - Example-based Color Grading

This tool democratizes some of artistic sense about colors by example-based approach. This tool can extract color palette from your favorite image and apply it on your output as post effect or LUT.

Features:
- Simple color grading post effect.
- It can generate its LUT (look up table) file for Post Processing Stack.
- You can adjust contrast and brightness of color palette.
- Fast GPU-based color statistics calculation.

Limitations:
- Color transfer process is automatic and linear, so that it's impossible to map bright pixel to dark pixel.
- Color mapping is only depends on the color palettes and it may map between different regions. e.g. sky color is mapped to ground color.
- Color filter is generated from the first frame and it doesn't consider succeeding frames.
