Researchers have developed CANIS, a novel framework for 3D object canonicalization that leverages semantic information from image-to-3D generative models. Unlike previous methods that relied solely on geometric cues, CANIS uses an informative rendered view as a semantic bridge to guide the generation of a proxy object in a canonical orientation. This approach allows for category-agnostic canonicalization without specific training or templates, using a sparse structural latent code to preserve geometry. Experiments on synthetic data and the OmniObject3D dataset demonstrate CANIS's effectiveness, even with partial observations, and show improvements in downstream tasks like 3D classification and part segmentation.
