PSPuht v1.2.0

Homebrew coder Mcidclan has released a new version of PSPuht, development library for upcoming developers that lets you add head and hand-tracking features to your homebrew projects using the PSP Go!Cam.
How it works:
PSPuht is based on image processing. Basicaly, it identifies pixels values probably belonging to skin color. This, in order to define a monochrome cloud corresponding to the tracked entity. Then, it evaluates the cloud position.

How to use it:
3 pspgu exemples are provided in the same archive in the library. Warning. For better results while using software working with this library, please, be aware of the following recommendations :

1. Use in a place, well lit by white light
2. Stand back to a white clean wall
3. Wear monochrome clothing, white or gray
4. For head-tracking, wear Turtleneck
5. For hand-tracking, wear long sleeves
