SOD



SUBTITLE

========



Raku bindings for the SOD image processing library



DESCRIPTION

===========



SOD is an embedded, modern cross-platform computer vision and machine learning software library that exposes a set of APIs for deep-learning, advanced media analysis & processing including real-time, multi-class object detection and model training on embedded systems with limited computational resource and IoT devices.
