Abstract: Examples disclosed herein relate to determining a segmentation boundary based on images representing an object. Examples include an IR image based on IR light reflected by an object disposed between an IR camera and an IR-absorbing surface, a color image representing the object disposed between the color camera and the IR-absorbing surface, and determining a segmentation boundary for the object.

Abstract: In one example, a projection capture system includes: a digital camera, a projector, and a mirror housed together as a single unit in which, when the unit is deployed for use with a work surface: the camera is positioned above the projector; the projector is positioned below the camera; and the mirror is positioned above the projector and configured to reflect light from the projector into the camera capture area. In one example, a projection capture method includes: establishing a camera capture area within which a camera can capture an image of an object; establishing a projector display area overlapping the capture area and into which a projector can project light; lighting the camera capture area with the projector; and positioning a specular glare spot from the projector lighting outside the camera capture area.
