The score element contains a floating point number between 0 and 10 (inclusive). This value is the Image Quality Analysis estimate of the likelihood no corner of the document is substantially missing from the image. A 10 indicates the corners pass this test and are good. A 0 indicates one of the corners fails this test and is substantially missing. Values in between 0 and 10 indicate one of the document corners is marginal and is partially missing from the image.
