Abstract

A method and an apparatus for identifying noise in a disparity depth image are disclosed. The method includes dividing the disparity depth image into a plurality of image blocks; for each of the image blocks, determining a reliable disparity value range in a disparity value range of the image block; and for each of pixels in the image block, determining whether the disparity value of the pixel is within the reliable disparity value range of the image block, and determining that the disparity value of the pixel is noise if the disparity value of the pixel is not within the reliable disparity value range. According to the noise identification method and apparatus, size of the selected blocks can be increased; therefore, higher computation efficiency can be obtained, and subsequent noise removal processing can be performed for only the identified noise pixels without affecting non-noise pixels.
