What are the extracted features in the IMAQ Extract Texture Feature VI?

[ryan123]

Hi,

I am new to LabVIEW and are in need of some help. I am moving a feature extraction procedure from MATLAB into LabVIEW, this involved gathering information on textures from a gray level co-occurrence matrix (glcm). I believe that the "IMAQ Extract Texture Feature VI" will include many of the feature I want to extract but it does not seem to be listed anywhere what these features are. When I treat the entire image as one region it outputs a 1-D array of 40 values, it would be great if someone could tell me what each of these values represents or point me in the right direction.

On a side note, the original code uses a glcm that is the average of four glcm with different displacement vectors ([0 1], [-1 1], [-1 0], [-1 -1]) representing 0, 45, 90, 135 degrees. How would this be possible in LabVIEW with only one input parameter for the co-occurrence matrix?

Cheers

Note: the final results do not need to be exactly the same, but the closer the better.

I think the best thing to do is consult the LabVIEW help http://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_extract_texture_feature/ . It describes the VI completely (with the assumption that you know the concepts it references). I'm not sure I understand your second question. Could you rephrase/restate it in a different way?

Hi Ryan,

Did you find the answer to the extracted features? I am trying to do something to detect textures but I have no idea on how to use the textures VIs

Thanks
