Abstract

The present disclosure provides a computer-implemented method of identifying spatial image modifications. The method includes receiving a original image and a adjusted image. The method also includes identifying a first subset of pixels comprising pixels in the original image that have a same first color value. The method also includes determining whether a second subset of pixels in the adjusted image all have a same second color value, wherein the second subset of pixels spatially correspond with the first subset of pixels. A spatial adjustment is identified if the second subset of pixels do not all have the same second color value.
