A Methodology for Visually Lossless JPEG2000 Compression of Monochrome Stereo Images Abstract A methodology for visually lossless compression of monochrome stereoscopic 3D images is proposed. Visibility thresholds are measured for quantization distortion in JPEG2000. These thresholds are found to be functions of not only spatial frequency, but also of wavelet coefficient variance, as well as […]

Comments Off on Weighted Guided Image Filtering
Posted in: IEEE 2017, MATLAB
Weighted Guided Image Filtering Abstract: It is known that local filtering-based edge preserving smoothing techniques suffer from halo artifacts. In this paper, a weighted guided image filter (WGIF) is introduced by incorporating an edge-aware weighting into an existing guided image filter (GIF) to address the problem. The WGIF inherits advantages of both global and local […]
