GPUMarkerTracker is a tracking software library for AR (augmented reality) markers. It utilizes GPGPU for fast and accurate tracking. It is intended for detecting markers from an HD resolution image so that small markers placed far from the camera can be detected. Each marker has a 12-bit payload with 9-bit CRC. The library does not produce false-positive detection errors of markers, practically.

This release improves the recognition speed by 20%. It also adds a function to write the rendered screen to a video file. The compiled binaries are now compatible with OpenCV 2.4.5.
