how to select a subset of image from a RGB image input

[bhai]

Dear Sir

I am having a data source . I want to select a portion of the image for pixel value calculation and identification by using RBF NN method.But the Labview software available in our laboratory is only the basic version.It is not having Pen attributes or Mouse control selection provisions.

How can I do it by using other tools in Labview .Else how can I build up a window by using MATLAB OR MATHSCRIPT.

Your help is much appreciated.

Hi Samir,

To obtain the toolsets that you need for your application, which include the Picture Control Toolset and MathScript, you will need to upgrade from the Base version of LabVIEW to Full or Professional. 

Once you have these toolsets, you can create a VI using pen attributes and mouse control selection provisions.  Try using LabVIEW shipping example titled "Pen Attributes and Image Subsetting" as a guide.  You can find this example by going to help >> NI Example Finder, selecting the browse tab, and then selecting the folder Building User Interfaces >> Controlling Front Panel Objects Programmatically.  This uses the Picture Control Toolset which should be included in your upgraded software.  Also, you can use the Picture Functions VIs found in your Functions Pallette for additional image analysis.

To create a MathScript window, go to Tools on your VI Toolbar, and then select MathScript Window.  Again, MathScript is not available with the base version of LabVIEW.  Please view the following help file for more information.  Thanks Samir!
