Abstract
A method and an apparatus for filtering an image using a guided image filter are described. A filter computes a filtering output using a guidance image. For calculating the filtering output confidence values associated to a filter input are taken into account. A confidence-weighted averaging is performed using the confidence values.
Claims10
A method for filtering an image using a guided image filter, wherein a filtering output is computed using a guidance image, wherein confidence values associated to a filter input are taken into account for calculating the filtering output.
An apparatus configured to filter an image using a guided image filter, the apparatus comprising a filter configured to compute a filtering output using a guidance image, wherein the filter is configured to take confidence values associated to the guidance image into account for calculating the filtering output.
A computer readable storage medium having stored therein instructions enabling filtering of an image using a guided image filter, which when executed by a computer, cause the computer to compute a filtering output using a guidance image, wherein confidence values associated to a filter input are taken into account for calculating the filtering output.
