Hello.

Depending on the type of image it is usually possible do some image
processing and subsequent segmentation to choose appropriate place for
the ROI and than measure variables in the RAW image. All this in macro
so user interaction could be avoided. I may help you to write the macro,
but the example of image and required data would be needed.
Feel free to write me off-list, if you are interested in.
