Feature Extraction and Classification

[nani689]

Hi ,

I am new to LabView. I need help to do my project .

Please find my attached image. In that image I have to show number of particles as 2 (because of 2 diff objects in that image) and then finding the features of that 2 pariticles (ex: area , circumference etc of the circle and triangle ) and last classification (if the image having less than 1000 pixels belongs to class A else class B).

Hi Swathi

As you requested, I would recommend you to these. try to learn, also attached vi for your ref.

Thank you very much Stephen for your immediate response with solution. With this I am able to find Area and Orientation of both triangle and circle.

By using area measurements how to do Classification? For example to classify the smaller object(for example no. of pixels<1000) belongs to class A and other objects belongs to class B etc.

Compare the output of Particle measurement with the limit you want and make it classify. If its not clear reply me,

I tried to do Classification but couldn't get the desired output.Please help me in doing Classification.

Thanks

Hello nani689,

the classification can be done by adding the "IMAQ GetImageSize" function to your block diagram.

The VI outputs the X and Y dimensions of your image. Just multiply the values and connect the result to a case structure.

One case would be 0..999 and another 1000..10000, Standard.

Best regards,

Peter
