MATLAB: How to find connected components

I am using bwconncomp() to find the connected components in an image.But,I get error.What can I do to rectify it?

Error:

Error using imageDisplayValidateParams

Expected input number 1, I, to be one of these types:

double, single, uint8, uint16, uint32, uint64, int8, int16, int32, int64, logical

Instead its type was struct.

Error in images.internal.imageDisplayValidateParams (line 11)

Error in images.internal.imageDisplayParseInputs (line 78)

common_args = images.internal.imageDisplayValidateParams(common_args);
