Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.

Can you get a better photo? Can you read the barcode manually from this photo?
You can use improfile to get something like this and decide if further processing is feasible, or think about what types of filtering might clean up the signal

If your camera has autofocus, the reflection off the table below may be confusing it. Place something nonreflective with no high contrast features (like a blank sheet of paper) on the table underneath the barcode.
