(Not recommended) Compare two bigimage objects for equality

The isequal function of the bigimage object is not recommended. Use the blockedImage object instead. For more information, see Compatibility Considerations.


tf = isequal(bigimg1,bigimg2) returns true if big images bigimg1 and bigimg2 have the same spatial referencing, underlying data type, and block size. Pixel values are only compared if the metadata is equal, and the comparison ends early when unequal pixel values are found. isequal does not consider file names, masks, and other class properties.
