The current solution is<br \/>\nmostly sequential and CPU-bound, resulting in a very low<br \/>\nprocessing throughput. My thesis presents a parallel batch<br \/>\nface registration pipeline, accelerated using a GPU-based<br \/>\nIterative Closest Point (ICP) registration and a GPU-based<br \/>\nNearest Neighbor face averaging strategy, alongside<br \/>\nin-place K-d tree construction, modern serialization<br \/>\nlibraries, and support for multi-GPU utilization. These<br \/>\noptimizations together achieve up to a 117x speedup of the<br \/>\nbatch face registration on consumer-grade hardware. The<br \/>\nwork includes extensive performance evaluations comparing<br \/>\nthe new GPU-accelerated implementations against their<br \/>\nCPU-bound counterparts.<\/p>\n","protected":false},"featured_media":26716,"template":"","meta":{"_acf_changed":false,"_links_to":"","_links_to_target":""},"university":[462,461],"thesis-year":[466],"class_list":["post-26976","thesis","type-thesis","status-publish","has-post-thumbnail","hentry","thesis-year-466"],"acf":{"autor":"Marek Horsk\u00fd","portret":"","vedouci":"doc.
