Do you have the image processing toolbox installed?

Note that imrect is not recommended. See here.

Hi @Farhan,

I understand that you are having issue with usage of 'imrect' object.

As mentioned by Cris above, imrect is not recommended. Use the new 'Rectangle' ROI object instead. You can also use the new ROI convenience function 'drawrectangle'. Try to update your code with told changes and retry and see if you encounter any issue.

Refer to the following documentation to know more about:

• Rectangle: https://www.mathworks.com/help/images/ref/images.roi.rectangle.html
• drawrectangle : https://www.mathworks.com/help/images/ref/drawrectangle.html

I hope this helps.
