Is there an IMAQ Vision function that calculates a co-occurrence matrix?

[Steverino]

I am wondering if there is an IMAQ Vision (VB) function that calculates a co-occurrence matrix of an image. This is the pre-cursor to a powerful set of texture descriptors.

Has anyone done this using IMAQ Vision?

Thanks!

Hi Steverino,

I would agree, a co-occurrence matrix can be a very powerful tool when working with texture analysis. Unfortunately, looking through the VB function reference I have not seen any that calculate a co-occurrence matrix. On the other hand, it certainly would not be too difficult to create your own.

I noticed that you have found the thread regarding texture analysis within LabVIEW. I believe they refer to some code to generate a co-occurrence matrix in LabVIEW. This might be a good place to start. I have saved the VIs to LabVIEW 7.0, maybe you will be able to use the code to create your own VB function.

Let me know if you have any other questions!
