Method and apparatus for processing depth image

摘要

An apparatus and method for processing a depth image. A depth image may be generated with reduced noise and motion blur, using depth images generated during different integration times that are generated based on the noise and motion blur of the depth image.

1. A method of processing a depth image, the method comprising:
determining at least one spatio-temporal neighboring pixel of a pixel of an input depth image based on a previous input depth image, an intermediate input depth image that corresponds to the input depth image, and a next input depth image, the previous input depth image corresponding to an input depth image preceding the intermediate input depth image in time, the next input depth image corresponding to an input depth image following the intermediate input depth image in time; calculating a weight value of the at least one spatia-temporal neighboring pixel using a calculated noise level, a calculated motion blur level, a calculated depth similarity, and a calculated intensity similarity; and generating an output depth image by updating a depth value of the pixel of the input depth image based on a depth value and the calculated weight value of the at least one spatio-temporal neighboring pixel.
