Method, medium, and apparatus of filtering depth noise using depth information

摘要

A depth noise filtering method and apparatus is provided. The depth noise filtering method may perform spatial filtering or temporal filtering according to depth information. In order to perform spatial filtering, the depth noise filtering method may determine a characteristic of a spatial filter based on depth information. Also, in order to perform temporal filtering, the depth noise filtering method may determine a number of reference frames based on depth information. The depth noise filtering method may adaptively remove depth noise according to depth information and thereby enhance a noise filtering performance.

1. A method of filtering depth noise, the method comprising:
obtaining depth information of a region in an image; and performing depth noise filtering on the depth information of the region using a spatial filter, wherein the performing comprises determining at least one of a size of the spatial filter and a coefficient of the spatial filter, based on the depth information, wherein at least one of the size of the spatial filter for a particular pixel and strength of the coefficient of the spatial filter for a particular pixel is related to a depth value for the particular pixel in the depth information.
