Abstract
A method for iterative optical character recognition includes: performing an optical character recognition pass on an image; identifying a first character located in a first portion of the image, wherein an identification of the first character is associated with a first character confidence level that is at least a threshold character confidence level; identifying a second character located in a second portion of the image, wherein a first identification of the second character is associated with a second character confidence level that is below the threshold character confidence level; and performing an additional optical character recognition pass on the second portion of the image to identify the second character a second time when the second character confidence level that is below the threshold character confidence level.
