<p><P>PROBLEM TO BE SOLVED: To provide a method for filtering a depth image by means of a frequency-close filter adapted to reduce coding errors while considering features of the depth image and a bilateral filter adapted to reduce remaining outliers while preserving depth discontinuities. <P>SOLUTION: Each depth image includes an array of pixels at locations (x, y), and each pixel has a depth. A moving window is applied to the pixels in the depth image. The size of the window covers a set of pixels centering around each pixel. A single representative depth from the set of pixels in the window is assigned to the pixel to produce a processed depth image. Then, each pixel in the processed depth image is filtered to correct outlier depths without blurring depth discontinuities to produce a filtered depth image. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
