 JavaCV also comes with hardware accelerated full-screen image display (`CanvasFrame` and `GLCanvasFrame`), easy-to-use methods to execute code in parallel on multiple cores (`Parallel`), user-friendly geometric and color calibration of cameras and projectors (`GeometricCalibrator`, `ProCamGeometricCalibrator`, `ProCamColorCalibrator`), detection and matching of feature points (`ObjectFinder`), a set of classes that implement direct image alignment of projector-camera systems (mainly `GNImageAligner`, `ProjectiveTransformer`, `ProjectiveColorTransformer`, `ProCamTransformer`, and `ReflectanceInitializer`), a blob analysis package (`Blobs`), as well as miscellaneous functionality in the `JavaCV` class. Some of these classes also have an OpenCL and OpenGL counterpart, their names ending with `CL` or starting with `GL`, i.e.: `JavaCVCL`, `GLCanvasFrame`, etc.

 Please keep me informed of any updates or fixes you make to the code so that I may integrate them into the next release. Thank you! And feel free to ask questions on [the mailing list](http://groups.google.com/group/javacv) if you encounter any problems with the software! I am sure it is far from perfect...

+Sample Usage

 The class definitions are basically ports to Java of the original header files in C/C++, and I deliberately decided to keep as much of the original syntax as possible. For example, here is a method that tries to load an image file, smooth it, and save it back to disk:
