20130170551 | Halo Reduction in Frame-Rate-Conversion Using Hybrid Bi-Directional Motion Vectors for Occlusion/Disocclusion Detection - A frame-rate converter reduces halo artifacts along edges of moving objects. Halo artifacts occur on interpolated frames where a moving object covers and uncovers pixels along its edges. Motion estimation among three original frames produces hybrid direction motion vectors that are bi-directional for background and objects, but are unidirectional for covered and uncovered regions, since motion vectors with large matching errors are deleted. Covered regions in the interpolated frame are detected as intersecting only a forward but no backward hybrid motion vector. Bi-directional motion estimation from the hybrid motion vectors of two original frames produces refined motion vectors for the interpolated frame. Refined motion vectors in the covered regions are deleted and replaced with hybrid motion vectors from the original frames. Hybrid motion vectors from the original frames are assigned to the critical covered regions rather than using interpolated vectors in the covered regions, reducing halo artifacts. | 07-04-2013 |
20150093015 | Visual-Experience-Optimized Super-Resolution Frame Generator - An image processor generates a Super-Resolution (SR) frame by upscaling. A Human Visual Preference Model (HVPM) helps detect random texture regions, where visual artifacts and errors are tolerated to allow for more image details, and immaculate regions having flat areas, corners, or regular structures, where details may be sacrificed to prevent annoying visual artifacts that seem to stand out more. A regularity or isotropic measurement is generated for each input pixel. More regular and less anisotropic regions are mapped as immaculate regions. Higher weights for blurring, smoothing, or blending from a single frame source are assigned for immaculate regions to reduce the likelihood of generated artifacts. In the random texture regions, multiple frames are used as sources for blending, and sharpening is increased to enhance details, but more artifacts are likely. These artifacts are more easily tolerated by humans in the random texture regions than in the regular-structure immaculate regions. | 04-02-2015 |

20150030072 | Spatial Scalable Video Coding using Non-Scalable Video CODEC - This invention discloses an encoding apparatus and a decoding apparatus for scalable video coding such that a non-scalable video decoder is usable for decoding a scalable video bit-stream comprising a base layer bit-stream and an enhancement layer bit-stream. In one embodiment, a source video frame is downscaled to give a downscaled video frame, which is then encoded into the base layer bit-stream. The difference between the source video frame and an up-scaled video frame reconstructed from the downscaled video frame in the base layer bit-stream yields a residual frame. The residual frame is partitioned into a number of residual sub-frames each having a resolution that is the downscaled video frame's resolution. The residual sub-frames are encoded into the enhancement layer bit-stream. Thereby, a non-scalable encoder is usable to encode both the downscaled video frame and the residual sub-frames, allowing both bit-streams to be decodable by employing only one non-scalable decoder. | 01-29-2015 |
