BGRABitmap

BGRABitmap is a set of units designed to modify and create images with transparency (alpha channel). Direct pixel access allows fast image processing. The library has been tested on Windows, Ubuntu and macOS, with widgetsets win32, gtk1, gtk2, Carbon (32 bit) and Cocoa (64 bit).

Graphics

BGRABitmap XYZ

XYZ is a colorspace that stores the actual stimulation of the average eye, relative to a max luminance (Y=1) considered as white. Fluorescent colors or light sources may have greater values for X/Y/Z so in this case you would rather use TXYZABitmap floating-point format to avoid saturation. Otherwise, for most use cases, when the image represents an object reflecting daylight, TWordXYZABitmap is sufficient.

Conscious Artificial Intelligence

This project is a quest for conscious artificial intelligence. A number of prototypes will be developed as the project progresses. This project has 2 subprojects: Object Pascal based CAI NEURAL API - https://github.com/joaopauloschuler/neural-api Python based K-CAI NEURAL API - https://github.com/joaopauloschuler/k-neural-api A video from the first prototype has been made: http://www.youtube.com/watch?v=qH-IQgYy9zg Above video shows a popperian agent collecting mining ore from 3 mining sites and bringing to the base. At the time the agent is born, it doesn't know how to walk nor it knows that it feels pleasure by mining. He has tact only (blind agent). The video shows learning, planning, executing and plan optimization.

Cheb's Persistency System

ABANDONED: The version currently in development is NOT compatible with the latest release and CANNOT be used separately from Cheb's Game Engine (not available yet). I am planning to release Chepersy 2 as a separate project someday, but it will not be compatible. I am truly sorry, but there were too many unstable hacks, I failed to reproduce their behavior. The future version will support 64-bit Intel and ARM platforms, will support fpc 3.x and will be based on reference counting (TInterfacedObject) A simple object database system for FreePascal. The persistence component features a powerful version compatibility system. Open architecture: you must manage some aspects by yourself according your needs. NOT compatible with fpc 3.x.
