Breaking the 3D Perception Bottleneck: VGGT Series Enables Dynamic High‑Fidelity Reconstruction

The VGGT series from KOKONI 3D and collaborators tackles three core 3D perception limits—unbounded sequence memory, dynamic‑static entanglement, and compute‑precision trade‑offs—by introducing StreamCacheVGGT, progressive decoupling, and HD‑VGGT, achieving O(1) memory streaming, 15%+ accuracy gains on dynamic benchmarks, and record‑high AUC on RealEstate10K.

Can AI Really Understand Dynamic First‑Person Scenes? Inside the New EOC‑Bench

The article introduces EOC‑Bench, a pioneering benchmark that evaluates multimodal large language models on dynamic first‑person visual tasks across past, present, and future time dimensions, presents its 3,277 questions, novel multi‑scale temporal accuracy metric, extensive model comparisons, and detailed error analysis revealing current models’ limitations in temporal perception and memory.
