# Does JPEG compression use a heuristic model similar to MP3?

I know that MP3 uses a compression heuristic that allows it to exclude storing frequency data outside a certain range due to the limits of human hearing.

Does JPEG employ some sort of non-linear quantization heuristic that accounts for the limitations of humans to perceive small differences in specific color bands or ranges?

Thank you in advance for any responses.
