pattern recognition

[patrick]

Dont know anything abou pattern recognition.

Is it easy to capture an image from the screen , screen.jpg, and identify
within that image specific patterns.

Say pattern A is an image stored as patternA.jpg. Is it possible to compare
patternA.jpg with the image at a specific rectangle within screen.jpg to see
if they are the same.??

Are there any java classes /packages that does this kind of thing.?


TIA
patrick

I don't know if there is any packet in java that handels that. What are you
going to use this for? Do you have several images, and that you want to pick
the one "closest" representing one of these? Is it a classification-problem?

You also have to define what "the same" means. If you mean identical it
probably exist some equlas-method that you can invoke on two Image-objects.

Cheers, Peter

suppose I want to find out which chess piece is displayed at the rectangle
at location (x,y) on screen.
I get an image for x,y say rectangle.jpg I already have several images
pawn.jpg,rook.jpg etc. I want to find out which of these is closest to
rectangle.jpg.

Check out the attached PDF, I scanned it from a book called "Neural Networks
and Pattern Recognition, CM Bishop"

I'm also working with classification in my thesis, creating an application
for something

I did send it to your regular mail, ok?
