Hi,

eigenvectors are a common technique of finding the most relevant pieces of data from a face one you have created a feature vector, as you mentioned this is not a trivial problem. This is really a forum for C# questions, you might want to start looking here http://en.wikipedia.org/wiki/Eigenface but this forum is really for discussing C# specific topics.

Mark.

Hi,

first you need to get the image data, pixel values, so that you can process them, you can do that efficiently in C# using the LockBits method of the bitmap class: http://www.bobpowell.net/lockingbits.htm After you have got the data you are goign to have to usesomeface detection algorithm, that is not relevant to this forum, you wil have to go and research on the web about the different algorithms that can be used. Here is a starting point: http://search.live.com/results.aspx q=face+recognition+algorithm&mkt=en-US&FORM=LVCP
