Hello, I would like to use ROI at different image multiple times, but it little bit harder. I need to save parametrs of first ROI and then use it at others.. for example if i select first image roi. Then I would like to select second square in different image but with same size as the first one.
Thanks for help

Select first image ROI
[B1 x y] = roipoly(I1);
Use selected ROI on another image
B2 = roipoly(I2, x, y);

When you're "done" with the rectangle you can right click inside it and select create mask. I think you can also double click inside it to "finish" it.
Alternatively you can use the rbbox() function if you think that's easier. Or if it's not a rectangle, but a polygon, you can use roipolyold().
