Global registration is applied to an entire page using anchors, lines, OCR results, and layout to adjust zones for a shifted, stretched, or skewed document. Either use a single global registration method or combine several methods.

Each registration method has its own threshold. If the registration confidence value of a specific method is below its confidence level, the next selected registration method in the sequence is used. If all registration methods fail, the defined zones are empty, and the confidence values are set to 0%.
