what is the homogeneous area in an image?

My question is that what is homogeneous area in an image and how it is used to conceal the objects in image? Please explain with a realistic example

I think we're the ones who should be asking "Please explain with a realistic example".

You can use a texture filter like stdfilt() inthe Image Processing Toolbox, or MSER in the Computer Vision System Toolbox to find fairly smooth areas.

I have no idea what you mean by using those areas to conceal other imagery.

Sir i am a beginner to the MATLAB and i am working on copy-move forgery attack. I was reading the Paper (Copy-Move Forgery Detection by Matching Triangles of Keypoints), and they have mention that this particular technique won't work if homogeneous areas are use to hide an object, as keypoint can't be extracted from those area.

Now, my question is that what actually homogeneous areas which can be used to hide an object? Plz try to explain in theoretical manner with some examples.

Steganography and forensics aren't my field. I can't explain the paper to you, and I can't give a tutorial on those topics. Since this is not really a MATLAB question, I suggest you read up more on the field you have chosen to go into and become an expert in. I suggest you start here: http://www.visionbib.com/bibliography/contents.html

Once you have a MATLAB question you can post your code here and people would be happy to try to help, as long as it doesn't involve in-depth knowledge of the steganography/forensics field and is just a regular MATLAB question, and doesn't involve algorithm development.
