摘要

Embodiment for detecting duplicate images include systems for determining that two or more of the images have similar key attributes such as attributes related to certain data in the images or image quality. Further, the embodiments include superimposing at least a portion of a first image of the two or more images over at least a portion of the second image of the two or more images, comparing the first image and second image; and determining whether the first image and the second image are identical.

主权项

1. A system for detecting duplicate images, the system comprising:
a computer apparatus including a processor and a memory; and a duplicate detection software module stored in the memory, comprising executable instructions that when executed by the processor cause the processor to: receive multiple images; determine that a first of the multiple images and a second image of the multiple images have similar key attributes; retrieve a document template associated with the first image and the second image; superimpose the first image and the second image over the document template; compare the first image with the second image and the document template; identify differences between the first image and the second image relative to the document template, the differences comprising a portion of the first image containing first markings and a portion of the second image containing second markings; determine that the portion of the first image and the portion of the second image are positioned in different and separate areas of each of the first image and the second image, wherein the first markings and the second markings are identical; and discard at least one of the first image and the second image based on one or more sources of the first image and the second image, image quality of the first image and the second image, or a respective receipt date associated with the first image and the second image.
