Implementation details

This project does not use artificial intelligence (AI), but rather mathematics.

The core logic of the project doesn't depend on any math or color library and includes the implementation of the following:

• converting between color models (e.g. sRGB to CIELAB),
• sRGB to spectral reflectance curve,
• subtractive color mixing using weighted geometric mean of reflectance curves,
• matrix operations,
• matrix inversion using LU decomposition,
• solving a system of linear algebraic equations using forward and backward substitution,
• the average color of the circular area of the image
• color difference using CIEDE2000,
• vector operations,
• median blur filter using sliding window and histogram,
• erosion morphological filter,
• median cut for color quantization,
• RGB to grayscale conversion based on luminance,
• and more.
