| dc.description.abstract1 | Motion estimation is a key component in dynamic point cloud
analysis and compression. We present a method for reducing
motion estimation computation when processing block-based
partitions of temporally adjacent point clouds. We propose
the use of an occupancy map containing information regarding
size or other higher-order local statistics of the partitions.
By consulting the map, the estimator may significantly reduce
its search space, avoiding expensive block-matching evaluations.
To form the maps we use 3D moment descriptors efficiently
computed with one-pass update formulas and stored
as scalar-values for multiple, subsequent references. Results
show that a speedup of 2 produces a maximum distortion
dropoff of less than 2% for the adopted PSNR-based metrics,
relative to distortion of predictions attained from full search.
Speedups of 5 and 10 are achievable with small average distortion
dropoffs, less than 3% and 5%, respectively, for the
tested data set. | pt_BR |
