1. A method for generating temporally correlated UV atlases, the method being executed by at least one processor, the method comprising:
generating a plurality of consistent UV charts associated with a current frame based on partition information associated with one or more previous frames;
removing one or more non-manifold vertices from the plurality of consistent UV charts based on assigning one or more incident faces associated with the one or more non-manifold vertices to corresponding UV charts among the plurality of consistent UV charts;
merging more than one of the plurality of consistent UV charts based on a similarity between the plurality of consistent UV charts and one or more reference charts associated with the one or more previous frames; and
generating temporally correlated UV atlases for the current frame based on aligning the plurality of consistent UV charts with the one or more reference charts associated with the one or more previous frames, wherein the aligning is based on packing information associated with the one or more reference charts.
