What is this?

K-Centroid is a novel downscaling algorithm designed to keep images close to the original, while also reducing noise and blur.

It uses K-Means to find the most common color for every tile of the downscaled image, producing detailed images at low resolution, without introducing the noise and artifacts of other methods.

Navigate to "Sprite" -> "K-Centroid Resize" to open the main window.

This extension is entirely written in lua, so depending on the settings you use it may take several seconds to downscale an image. I'm working on performance improvements, but I'm not an efficiency expert. If you'd like to help make it faster, please contribute here: https://github.com/Astropulse/K-Centroid-Aseprite
