One or more monocular cues are extracted from an original image and combined to enhance depth effect. An original image is acquired and segmented into one or more objects. The objects are identified as being either in the foreground or the background, and an object of interest is identified. One or more depth cues are then extracted from the original image including shading, brightness, blur and occlusion. The depth cues may be in the form of one or more intermediate images having an improved depth effect. The depth cues are then combined or applied to create an image with enhanced depth effect.

Why it's free to use
- Filed March 9, 1998 and granted August 5, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 9, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 9, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
