Abstract
Official abstract text for this publication.
Filtering lower quality images or sequences of images with higher quality images or sequences of images. The filtering is utilized in a post-process, decoded, or encoded images including multiple sets of images that are filtered and/or combined. Different image features including, for example, quality, frequency characteristics, temporal resolution, spatial resolution, number of views, or bit-depth are present in the images. In one embodiment, the filtering comprises a multi-hypothesis filtering and the confidence value comprises a difference between the filtered sample and samples lying within a filter support. The post processes images are then stored or distributed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for processing samples of an image or sequence of images, the method comprising: encoding a first set of samples with a first encoding process; encoding a second set of samples with a second encoding process; filtering reconstructed samples of the first set based on information associated with at least one of the first encoding process and the second encoding process; and combining the filtered reconstructed samples of the first set with…
