Select ROI using mouse

Is there a way for me to select a specific region-of-interest within an image using the mouse? Like click-and-drag to highlight the area for the ROI.

The idea is to do different processing for different ROIs. So once the ROIs are selected, they will be processed differently.

Oh I've just found the Mouse module http://www.roborealm.com/help/Mouse.php

I suppose I should start with this one, and built up the mouse-controlled ROI selector...

I think what you want instead is the Crop module which will reduce the image to the space specified by 4 coordinates. After the module and other processing, you would use the Marker module to restore the image to the source and then use another Crop module to crop a different section and so on.

If, however, you want to split the image into equal units then the Split_Image module is best for that since it will crop each area, process the statements within its compound statement and then crop to the next part. It also has the possibility to crop to specific blobs in case what you have is not easily divided into units.


If you are still unclear on what to use, post an example image that you need split/divided/cropped in some way.

Oh Crop is perfect! Thanks a lot Steven. I am evaluating the software for a potential project I'm working on, and if everything goes well, definitely will get a commercial license.
