Paper Abstract

The depth of an object in stereo is determined by the horizontal separation (i.e., disparity) of the object between the left and right images. For digitized images the disparity is in increments of pixels. Since all points in a given depth plane have the same disparity, the `cut- plane' procedure can theoretically eliminate a given depth plane by simply subtracting the stereo image pairs from each other after horizontally shifting them a specific number of pixels. Mathematical analysis and simulations with abstract objects have determined that both the length and disparity of objects with widths greater than one pixel may be modified by the `cut- plane' procedure; even when the object is not in the depth plane being eliminated. To what extent an object is modified depends on the original disparity and width of the object. The application of this procedure to chest x rays is presented with a demonstration of how certain pitfalls of the `cut-plane' procedure can be surmounted.
