    "subtitle": null,
    "abstract": "Visual image segmentation is the process by\nwhich the visual system groups locations that\nare part of the same object. Can knowledge of\nobjects influence image segmentation, or is the\nsegmentation process isolated from object\ninformation? The use of object knowledge at this\nstage of vision might seem premature, as the goal\nof segmentation is to provide input to object\nrecognition. However, purely bottom-up image\nsegmentation has proven a computationally\ndifficult task, suggesting that a \"knowledge-\nbased\" approach might be required. W e\naddressed this issue using two segmentation\ntasks: Subjects either determined whether a\nsmall 'x' was located inside or outside the region\nsubtended by a block shape, or they determined\nwhether two small x's were on the same shape or\ndifferent shapes. The familiarity of the shapes\nwas manipulated, and subjects were fastest to\nsegment the visually familiar shapes. These\nresults suggest that image segmentation can be\npartly guided by information about familiar\nobjects, consistent with knowledge-based image\nsegmentation models.",
