I am going to design a Fingerprint Recognition System that involves recognizing fingerprint from image, feature extraction and matching. I am willing to implement it through C and Python, that library will be written in C and docked to Python as a module. Here are my questions:
Is there any books that you can recommend me in this field (except Handbook of Fingerprint Recognition)?
I need a device that will simply scan the fingerprint and save it as an image which I can use later through my code. But I can't seem to find one. All of them have their own software for matching and don't allow me to bypass it. Are there any known devices for such task or shall I write my own driver for one of them?
Would you recommend OpenCV?
This is clearly computer vision task, so the answer is: yes, OpenCV is good for the task.
The question of fingerprint recognition already was discussed in in OpenCV forum. So you can start from here .

I like to stream a video in the internet,and I search to find some streaming tools to help me in this manner. I can find one open source dvblast
Now, Is there another open source or paid tools can help me?
Is there any python package to do this?
**hint : I want to use It for stream video like TV shows.
You can use something like:
1)http://www.iis.net/downloads/microsoft/smooth-streaming
2)http://www.ffmpeg.org/ffserver.html
3)http://www.videolan.org/vlc/
that vlc use dvblast!

I'm trying to find a good and stable network packet sniffer in python, that allows me to do exactly the as I used to with tcpdump.
I found this pycap but it does not seem to be that stable... Another options would be Scapy but it does not handle reassembling TCP streams.
Any other options? Or am I wrong about pycap?
If you're worried about the stability of other python based packages, you can use python's ctypes library to dynamically load in libpcap.so.
You can find out more on using libpcap.so over here while the ctypes documentation is here.
Take a look at PyShark. It allows you to sniff specific interface continuously.

I like the matplotlib documentation at this web address,
http://matplotlib.org/index.html
but I cannot access it when my laptop computer is offline (traveling, etc.)
Can anyone recommend a way to download the html docs for matplotlib?
This is possible for the python docs.
Thanks.
Bill
The whole matplotlib.org website is stored in a github repository. You can download the whole thing from:
https://github.com/matplotlib/matplotlib.github.com
(direct zip link: https://github.com/matplotlib/matplotlib.github.com/archive/master.zip)
The result will probably be a pretty big zip file. Alternatively, as others have said, you can build the documentation yourself by following:
http://matplotlib.org/devel/documenting_mpl.html
HTH
The Documentation is available as a PDF for download at:
http://matplotlib.org/Matplotlib.pdf

An ARC file is a lossless data-compression format.
http://en.wikipedia.org/wiki/ARC_%28file_format%29
I've tried googling some, but the Python ARC readers are 404 errors, or cannot be found.
Anyone know of any library I can use?
If you are able to use SWIG then possibly the ARC source code from FreeBSD could be used. Or you could have a look at the source, and perhaps reimplement it in Python. I remember ARC and it did not last very long as a popular tool so I suspect that it is not overly complex.

Does anyone know of a Python class similar to Java Robot?
Specifically I would like to perform a screen grab in Ubuntu, and eventually track mouse clicks and keyboard presses (although that's a slightly different question).
If you have GTK, then you can use the gtk.gdk.Display class to do most of the work. It controls the keyboard/mouse pointer grabs a set of gtk.gdk.Screen objects.
Check out GNU LDTP:
GNU/Linux Desktop Testing Project (GNU
LDTP) is aimed at producing high
quality test automation framework
[...]
Especially Writing LDTP test scripts in Python scripting language
As far as the screen grab, see this answer. That worked for me. Other answers to the same question might be of interest as well.
Check out the RobotFramework. I do not know if it will do the same things as JavaRobot, or if it will do more. But it is easy and very flexible to use.
