International Classification:

H04N 13/00
H04N 13/02
G06T 3/40

Abstract:

Each of plural devices includes a laser emitter and a camera for detecting reflections of laser light emitted by the device, so that plural of the devices can generate their own depth maps showing images within the field of view of their cameras. The resolution of each depth map may be improved by accessing a data store of prior images of objects and combining the prior images using super-resolution with current images of the depth maps.

International Classification:

G06K 9/46
G06T 5/00

Abstract:

To reduce the random noise in a depth map that is rendered using colors to convey the various depths, pattern recognition may be used to selectively apply noise reduction or to modulate the strength of the noise reduction. In this way, the potential adverse effect on the detail/sharpness of the image can be ameliorated. For example, in an image of a person, the skin does not have any sharp edges so noise reduction can be applied to such an image with little adverse consequence, whereas noise reduction applied to the image of a person's eye can cause loss of the detail of the iris, eyelashes, etc. Using pattern recognition on objects in the image, the appropriate level of noise reduction can be applied across an image while minimizing blurring/loss of detail.
