Need help on ROI and Update Graph

  • Follow


Hi all,

I need really your helps.

I would like to develop a GUI where there are two images/figures which are (1) image with ROI function and (2) figures for graphs with three buttons for graph of Edge Spread Function (ESF), LSF (Line Spread Function) and MTF (Modulation Transfer Function).

My questions are:

1) Is it possible that I can flexibly rotate the rectangular ROI on my image? Do i need additional script for that?

2) Can I create automatically updated graph? Meaning that whenever i change the location the ROI, the curve (ESF, LSF or MTF) is automatically changed/updated.

Please share if you have any tips/helps how to do that.

Thanks for your helps.
