Thread Subject: classification of color images

Hello Friends,

I am trying to classify images(colour). For eg a certain type of medical image(MRI,CTSCAN,Fundus..etc). I am looking for algorithms that can classify images as MRI or non-MRI,fundus-non-Fundus..etc.

What are the simple classification techniques used for such?

regards

Hello,

I am looking at some simple learning algorithm. Want to avoid a neural network,if poossible.

Look in the header of the image. Any decent medical image will have
info in the header that will identify all kinds of stuff. No need to
even *look* at the image. Or you could just ask the doctor whom you
got the images from "What department do you work in?" I'm having
trouble envisioning any real world situation where this would be
needed - is this just some sort of hypothetical exercise?

Hi Image Analyst,

I want to host an application that shall detect a certain type of image(say colour scan images). users can put inb any image(scenery/face images ...etc). I am writing an algorithm to classify them images. You mentioned header of an image. How can I extract the header of an image?

regards,
Vinod

Note that you will need a Matlab Network license in order to host a
Matlab application that is accessible to the public (but possibly not if
it is only accessible to your organization.)

Vinod:
It really depends on the type of image. Go to http://www.wotsit.org/
for a pretty big list of image formats. You really have to decide
upon a subset of image formats that you will try to import, because
it's impossible to handle every known and unknown type of file format
that someone could give you.
Good luck,
ImageAnalyst
