Adaptive Loop Filter Technique for 3D-HEVC Standard

This paper proposes the use of adaptive loop filtering (ALF) technique for 3D-HEVC standard in-loop filtering. This filter uses Wiener -- based method to minimize the Mean Squared Error between filtered pixel and original pixels. Performance of adaptive loop filter in picture based level is evaluated. Test model HTM-6.2 is used to demonstrate the results. Results show up to of 0.2 dB PSNR improvement in Luminance component for the texture and 2.1 dB for the depth. In addition, up to 0.1 dB improvement in Chrominance component for the texture view after applying this filter in picture based filtering.
