Trials of pycam example code

I am trying to learn something about computer version, and Python is my first choice of the coding tool. After several hours of searching, I found pycam. There are several sample codes given by the pycam. What I have downloaded was the ``pycam-read-only'' folder in which are three subdirectories:

• c-vs-py
• openeyes
• pycam

To install the pycam, just find the ``setup.py'' in the subdirectory named ``pycam'' and run ``sudo python setup.py install.'' Furthermore, what you need to install might include the follows:

• python-opencv
• python-pygame
• libcv-dev
• libcvaux-dev
• libhighgui-dev

The lib*-dev are (my guess) for the cpp codes, which need to include the cv.h and highgui.h.

So far, my testing results are:

1. pycam-read-only/pycam/examples/: Okay, but the fps are low
2. pycam-read-only/pycam/examples/opencv: Failed. There were errors I don't know how to resolve yet. Only the ``cam-histo.py'' can be executed, after remove the ``cv.CV_VERSION'' at line 88. (the CV_VERSION seems not in my OpenCV.)
3. pycam-read-only/pycam/pycam/: Failed
4. pycam-read-only/c-vs-py/c_examples: Okay
5. pycam-read-only/c-vs-py/py_examples: Some codes showed errors. They are harris_opencv.py, objectDetect.py, and people_only.py.
