Implementing Machine Vision Systems with a Dynamically Typed Language
HornetsEye is a machine vision extension using existing free and open source software (FOSS) which facilitates capture, processing, display, and recording of live video. This work is about combining the productivity gains of a modern scripting language and real-time performance in a single system.
The core of the system is implemented in Ruby. In order to achieve high performance, the GNU C compiler is used for just-in-time compilation. The system provides an internal Domain Speciﬁc Language (DSL) for manipulating uniform arrays.
Finally the system comes with a comprehensive set of classes for input and output. There is support for DC1394-, V4L-, and V4L2-compatible cameras, ALSA sound devices, image and video ﬁles, the Microsoft Kinect, and X.Org display. Furthermore there is Qt4-integration for developing graphical user interfaces.
