Systems and methods for image archaeology

摘要

Systems and methods are described for determining manipulation history among a plurality of images. The described techniques include selecting a pair of images from the plurality of images, detecting one or more manipulations operable to transform one of the images to the other, and based on the manipulations detected, determining a parent-child relationship between the pair or pairs of images. The described techniques can further include repeating the selecting two images, detecting manipulations, and determining the parent-child relationship for each pairs of images in the plurality of images, constructing a visual migration map for the images, and presenting the visual migration map in a user readable format.

1. A method for determining manipulation history among a plurality of images, comprising:
a) selecting a first image and a second image from the plurality of images; g) detecting if one or more manipulation are operable to transform the first image to the second image or the second image to the first image; e) determining an existence of a parent-child relationship between the first image and the second image based on the detection of the one of more manipulations, if any; g) presenting the determined existence of the parent-child relationship in a user readable format; e) determining the existence of a parent-child relationship for each pair of images in the plurality of images, and f) constructing a visual migration map for the plurality of images based on the determined existence of the parent-child relationship for each pair of images in the plurality of images prior to the presenting the determined parent-child relationship, wherein the presenting comprises presenting the visual migration map.
