Prithwish,

In the documentation for 'insertMarker', it says that the function expects the image input to be one of these types: uint8, uint16, int16, double, or single. A binary image is stored as a logical array, so is not a valid input.

You can always convert your binary image into one of the supported data types and use that as input to the 'insertMarker' function (using the 'single' function, for example). If you wanted to, you could also convert the output back into a binary image afterwards (with the 'logical' function).
