ROI

Hi,
I would like to use Roborealm for an industrial application. I need to check 8 diffrent areas (ROIs) . I have to binarize each roi with different thresholds and count the white pixels.
I have looked high and low in the software and I can't figure out how you create diffrent inspection areas (ROIs).
Is it possible with this fantastic software?

Rock,
What you would do is to use the Crop module to isolate the different areas into single images, process for a different threshold, etc. and then use the Marker module to restore the image to the original so that the next cropped area can be specified.
Let me know if you need an example to that effect.
STeven.

If I know that I always only need to analyze a certain region of the image, I create an black and white image with the same resolution and make the ROI (or multiple ROI) as white regions on a black background. I then AND this image with the original image. This is gives a nice and visual approach which is useful for prototyping. If you are working with the API, the multiple crops is the way to go, but it gets really long in the interface. (Gee code folding in the roborealm IDE?)
have fun!

My images are giving it hiccups! (Mono bmp for the mask since jpeg can make white -> grey)
