Can I extract the ROIs into separate images for classification?

If I use the ROI tool to generate a bunch of ROIs, is it possible to extract those ROIs into separate images? It seems to me that some classification schemes, like the example that use HOG features, require separate images. I have one image of a bunch of resistor symbols. Rather than taking a bunch of images, it'd be nice to be able to just extract them from the ROIs themselves.

Could you clarify which ROI tool you are using? I did something like this before and used a script to save those ROIs into separate images. The logic was just like I_ROI = I_original(...) and imwrite(I_ROI). But it seems you are using more advanced tools :/
