Abstract
An attribute inter-prediction framework using motion search criterion, proper reference, attribute projection and in-loop filter is described herein. An alternative motion estimation strategy incorporates color distance into the motion search criterion where geometry and attribute motion are jointly searched which leads to a single motion vector associated with each predicted block. The composed distance is the weighted sum of color and geometry distance. With the composed distance, two new types of search criterion are used to estimate the motion vectors: using the nearest neighbor composed distance, using the minimum composed distance based on the search of composed distances associated with each reference point within the search window. A dedicated attribute coding scheme using a two-pass motion search scheme, where the first pass is based on geometry only, and the second pass targets on eliminating temporal attribute redundancy. An in-loop filter can be applied to the projected attributes.
