Claim One:
1. A computer-implemented method for detecting motion in images, comprising: receiving, by a computing system, a first image that was captured by a camera; receiving, by the computing system, a second image that was captured by the camera; generating, by the computing system and using the first image and the second image, a mathematical transformation that indicates movement of the camera from the first image to the second image with respect to a scene that is reflected in the first image and the second image; generating, by the computing system and using the first image and the mathematical transformation, a modified version of the first image that presents the scene that was captured by the first image from a position of the camera when the second image was captured, wherein a position of the camera when the first image was captured is different from the position of the camera when the second image was captured; and determining, by the computing system, a portion of the first image or second image at which a position of an object in the scene moved, by comparing the modified version of the first image to the second image, wherein comparing the modified version of the first image to the second image includes: calculating, by the computing system, a spatial gradient of the first image or the second image to identify a portion of the first image or the second image at which an edge of an object is present; identifying, by the computing system, a pixel difference between the modified version of the first image and the second image; and determining, by the computing system, a portion of the first image or the second image at which a moving edge of the object is present, as a result of (i) the calculated spatial gradient indicating that the edge of the object is present in the portion of the first image or the second image, and (ii) there being an identified pixel difference between the modified version of the first image and the second image at the portion of the first image or the second image.
