APCA (Accessible Perceptual Contrast Algorithm) is a new method for predicting contrast for use in emerging web standards (WCAG 3) for determining readability contrast. APCA is derived form the SAPC (S-LUV Advanced Predictive Color) which is an accessibility-oriented color appearance model designed for self-illuminated displays.
AMD ROCm Performance Primitives (RPP) library is a comprehensive high-performance computer vision library for AMD processors with HIP/OpenCL/CPU back-ends.
The Colour Contrast Analyser (CCA) helps you determine the legibility of text and the contrast of visual elements, such as graphical controls and visual indicators.
𝜟𝜱✴︎ or Delta Phi Star is a variant method of determining lightness contrast, and a sibling of APCA and SACAM. It is a simplified version using easily invertible standardized maths, however it lacks some useful properties such as polarity sensitivity. In fact, it is intended for applications where a "general" simplifed perceptual contrast is des…
For a number of years now, work has been proceeding in order to bring perfection to the cryptically conceived concept of contrast that would not only supply inverse reactive spatial quanta for use in unilateral phase detractors, but would also be capable of automatically syncing cardinal grameters. Such an algorithm is the Turbo Contrastulator.
