APPARATUS AND METHOD FOR DEPTH BASED IMAGE RENDERING ON MOBILE BROADCASTING
摘要
An apparatus and a method for rendering a depth based image in mobile broadcasting are provided to apply a discontinuous maintenance filter to a depth image, thereby minimizing distortion of the depth image. A discontinuous maintenance filter(111) smoothes a depth image correspondingly to gradient amplitude of the depth image. An adaptive smoothing filter(115) calculates a gradient degree of the depth image transmitted from the discontinuous maintenance filter. Only when gradient amplitude is larger than a preset value, the adaptive smoothing filter applies a filter feature according to a gradient direction to the depth image. The adaptive smoothing filter transmits the depth image to an encoding module(120). The encoding module transmits a reference image and the depth image.
