Your Face in 10 minutes... with Macruby!
summary
Builds a macOS app in Ruby using MacRuby and Xcode templates that captures 640x480 video with AVFoundation AVCaptureSession, shows a live preview layer and samples frames on a GCD queue. Uses CIDetector face features (left eye, right eye, mouth) for detection, overlays graphics (bowler hat, glasses, mustache) in real time, and sends images to Face.com for recognition because local recognition isn’t feasible—Ruby lacks robust linear algebra libraries. Demo works but recognition fails under bright light.
