1D Histogram with openCV

Hand tracking with OpenCV

These days I am working on a new hand tracking program. I wrote a OpenCV program to track hand based on color. Still I’m trying to remove the background noise :).

Here are some testing pictures.

Installing HandVU on XP

some notes: link

I have already installed OpenCV , Microsoft Visual studio 2005 , Microsoft DirectX SDK (August 2006) and Microsoft platform SDK . Here I describe how I got the HandVU working on my PC. Hope it will help you.

After you have installed necessary software your environment variables (My computer->properties->Advanced->environment variables) should be like this according to your installation paths.

I have installed OpenCV and DirectX in D:\

I couldn’t find all the DirectX SDK libs in my installation folders. You can use these Visual Studio project files for the DirectShow SDK baseclasses and samples to get those.

These are the dll file files you need before compiling HandVU.

1. Now open the HandVU source folder and locate HandVU folder. Compile it with visual studio. I got errors...

type #include to HanVu_img.Cpp

2. Same thing was done with the cubicals folder.

This will give an error. To correct it add II_TYPE_FLOTE to Preprocessor Definitions. Then type #include CascadeFileScanner.c
