Method of fusing mesh sequences within volumetric video

A computer-implemented system for smoothing a transition between two mesh sequences to be rendered successively;

• said computer-implemented system comprising:
• a. a processor;
• b. a memory storing instructions which, when executed by said processor, direct said processor to performing steps of:
• i. providing first and second mesh sequences {1} and {2} formed mesh frames, respectively, to be fused into a fused sequence;
• said first mesh sequence positioned before said second mesh sequence within said fused sequence;
• ii. selecting mesh frames gn and gm being candidates for fusing therebetween;
• said candidates gn selected within a first mesh frame group {G1} positioned in an end portion of said first mesh sequence {1} and candidates gm selected within a second mesh group {G2} positioned a start portion of said second mesh sequence;
• iii. calculating geometric rigid and/or non-rigid transformations of candidate frames gn and gm belonging to said first and second mesh sequences {1} and {2};
• iv. applying calculated geometric rigid and/or non-rigid transformations to candidate frames gn and gm belonging to said first and second mesh sequences {1} and {2};
• v. calculating textural transformations of said candidate frames gn and gm belonging to said first and second mesh sequences {1} and {2};
• and
• vi. applying calculated textural transformations to of said candidate frames gn and gm belonging to said first and second mesh sequences {1} and {2}.
