Using imfreehand() on MatlabMobile

I wrote a code for selecting a ROI via imfreehand(). It works well with the standard Matlab on my PC.

When I run it on Matlab mobile (such as on my ipad) the code remains on "uiwait" and I'm not allowed to draw my region of interest.

Could you assist me?

I understood that you are facing issues while using “imfreehand()” function in MATLAB Mobile version. Try below troubleshooting steps to resolve your query.

• “imfreehand()” is not recommended so try to use the new “Freehand” ROI object and you can use the new ROI creation convenience function “drawfreehand()”. Another option is the “AssistedFreehand()” object, which enables you to hand-draw a shape that automatically follows the edges in the underlying image.
