i want to know how people can develop some program which can compare 2 pictures and program tells you if those pictures are same

[Momerath]

Depends on your definition of "same". You can compare bit by bit, do color maps, intensity maps, color histograms, etc.

[Tonchi]

this sound very complicated

[wwarren]

Well, do you want to know if they are exactly the same file?

[Tonchi]

no...my idea was to create something like CODIS (from CSI: Miami)

[wwarren]

CODIS is a system for storing and retrieving DNA profiles. I think what you're asking is if it's possible to create a system that can look at 2 different photos of a person, and tell you if they're the same person.

Am I on the right track?

[Tonchi]

yes...yo're correct

[wwarren]

Okay.

This is not a simple task. I suggest you begin by Googling for "facial recognition in c#" and do some further reading into the algorithms and concepts that you will need.

Good Luck!

what is element siblings in xml

[wwarren]

In an XML document like this:

<parent>

    <child1></child1>

    <child2></child2>

</parent>

The nodes child1 and child2 are siblings.

[Tonchi]

but if there is 4 child elements then they are all siblings, right???

[wwarren]

Yes. That's correct

<parent>

    <child1></child1>

    <child2></child2>

    <child3></child3>

    <child4></child4>

</parent>

Child nodes 1-4 are all siblings.
