Hey @Hridya PI, i assume that error you are facing might be because of the below reason:
Toolbox Missing/Not Installed: createMask is part of the Image Processing Toolbox. If you don't have this toolbox installed, or your MATLAB license doesn't include it, you'll get this error.
Incorrect Usage: createMask is usually a method of an ROI (Region of Interest) object (e.g., imrect, imellipse, drawrectangle, drawcircle). You don't call it directly with an image, I assume that l_i is an image and not a ROI object.
