%%Error Occured%%
Error using imlincombc
Function imlincomb expected its array input arguments (A1, A2, …) to have the same class.
Error in imlincomb (line 86)
Z = images.internal.imlincombc(ims, scalars, outputClass);

#### Best Answer

Check the classes of seg,gt. They should be of same class. Convert them to same class using double or uint8.
