Selecting multiple regions of interest with roipoly

13 visualizzazioni (ultimi 30 giorni)
I intend on using roipoly to select regions of interest in a plot. My question is; is it possible to select multiple separate ROI on the same plot? I also intend on applying a mask to the roipoly so that i can apply the same ROI to multiple matrices without plotting them. Because a mask works by setting every point outside the ROI to 0 and inside to 1, does this mean that the actual values inside the ROI are overwritten? Thanks in advance to anyone with clarification on this

Did you ever find the code to do this? I have the same exact problem and can't find anything on the internet.

I haven't heard back from you so it seems like you weren't able to do it. I'm attaching a demo for you.

You have to create multiple mask and OR them together.
