Error in imageDisplayValidateParams (line 12) validateattributes(common_args.CData, {'numeric','logical'},… Error in imageDisplayParseInputs (line 79) common_args = imageDisplayValidateParams(common_args); Error in imshow (line 220) [common_args,specific_args] = … Error in Untitled (line 24) imshow( I);

Best Answer

As the error message states, your input to imshow is of class SURFPoints. imshow expects an image (i.e. a numeric or logical array), it has no idea how to display SURFPoints as an image.
Neither have I. Pass a proper image to imshow.
