Abstract
Pixel-based and region-based methods, computer program products, and systems for detecting, flagging, highlighting on a display, and automatically fixing edge violations in stereoscopic images and video. The highlighting and display methods involve signed, clamped subtraction of one image of a stereo image pair from the other image, with the subtraction preferably isolated to a region of interest near the lateral edges. Various embodiments include limiting the detection, flagging, and highlighting of edge violations to objects causing a degree of perceptual discomfort greater than a user-set or preset threshold, or to objects having a certain size and/or proximity and/or degree of cut-off by a lateral edge of the left or right eye images of a stereo image pair. Methods of removing violations include automatic or semi-automatic cropping of the offending object, and depth shifting of the offending object onto the screen plane.
