Claim One:
1. A method for reducing boundary jitter during a document image capture session, the method comprising: receiving a sequence of one or more video frames from an image capture device, wherein at least some of the video frames comprise a target object to be captured; identifying one or more polygons in the video frames; applying one or more intra-frame filters to the polygons to select one or more candidate object boundaries, wherein the one or more candidate object boundaries correspond to one of the polygons from a respective one or more of the video frames; applying one or more inter-frame filters to the one or more candidate object boundaries to select a particular one of the one or more candidate object boundaries that bounds the target object, wherein applying one or more inter-frame filters comprises: calculating an area measurement corresponding to a minimum bounding box of the candidate polygon; comparing the area measurement to a set of previously stored measurements to determine a variance; selecting the candidate polygon when the variance is within a predetermined threshold; and rendering a visual boundary on a user device display screen, wherein the visual boundary corresponds to the candidate polygon; and sending a representation of the particular one of the one or more candidate object boundaries to a graphics processor to be visually displayed on a display screen of the image capture device.
