New CRePE method improves camera control in video generation

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Curved Ray Expectation Positional Encoding (CRePE), a novel method for enhancing camera-controlled video generation. CRePE addresses limitations in existing methods by providing a Unified Camera Model-compatible encoding that accurately represents projected-path geometry, even with wide-angle and fisheye lenses. Implemented via a Geometric Attention Adapter within video Diffusion Transformers, CRePE improves camera control stability and perceptual quality, outperforming baseline methods in various metrics.

    CRePE: Curved Ray Expectation Positional Encoding for Unified-Camera-Controlled Video Generation

    Camera-conditioned video generation requires positional encoding that remains reliable under changes in camera motion, lens configuration, and scene structure. However, existing attention-level camera encodings either provide ray-only camera signals or rely on pinhole camera geom…
