Checking pixel values

Customer requires that RGB pixel values at the same pixel location can not be 0,0,0 or 255,255,255. Is it possible in Imagine Advantage to automatically check that this requirement is not violated? BB

Re: Checking pixel values

Sure. Probably the easiest way is to create a model which performs a Stack Total and look for occurences of 0 or  765. 

 

Remember that an existing model can be executed using IMAGINE Advantage.

Re: Checking pixel values

Hello Ian, and thank you for the quick reply.

 

Unfortunately we are not familiar with Erdas Imagine models. Is it possible to run such a check by the batch command tool without a model? And/or is there a interactive tool which I have not found yet?

I have also tried to run an existing model from the library (Histo_Eq.gmd), it will not run.

Is it likely that a model for this exists somewhere? And would you give a hint of how to run models?

 

Kind regards,

Bjørn B.

Hi Bjørn,

 

the easiest way to run a spatial model is to launch the Spatial Model Editor (which you're going to need access to anyway to build the model you want).

 

But to simply run an existing Spatial Model you can go to the Toolbox tab / Common group / Spatial Model Editor pull down and select Launch Spatial Model. To be able to interact with the model via a dialog to provide input names, processing parameters, etc., the model will have to have been designed to use Port Input operators. But once you have that type of model it can easily be re-used (you can also add them to a custom Tab on your Ribbon, or run them in Batch).

 

There's an eTraining video on how to use Port Inputs here:
