What is WorldScore
WorldScore is a unified evaluation benchmark for world generation models proposed by Stanford University. It decomposes world generation into a series of next-scene generation tasks, enabling unified evaluation of different methods through explicit camera-trajectory-based layout specifications. WorldScore evaluates three key aspects of generated worlds: controllability, quality, and dynamics. The benchmark includes a carefully curated dataset covering 3,000 test samples, including diverse worlds that are static and dynamic, indoor and outdoor, and realistic and stylized.
Main Features of WorldScore
- Unified Evaluation Framework: WorldScore provides a unified evaluation framework for measuring the performance of different world generation models. It decomposes world generation tasks into a series of next-scene generation tasks, enabling unified evaluation of different methods through explicit camera-trajectory-based layout specifications.
- Evaluation Dimensions: It evaluates generated worlds from three key aspects: controllability, quality, and dynamics.
- Multi-Scene Generation: WorldScore is the only benchmark that supports multi-scene generation and can evaluate model performance in generating consecutive scenes.
- Unification: It can uniformly evaluate 3D, 4D, image-to-video (I2V), and text-to-video (T2V) models, providing a comprehensive evaluation framework.
- Long Sequence Support: It supports generating multiple scenes and evaluates model performance in long-sequence generation tasks.
- Image Conditioning: It supports image-based conditional generation and is suitable for image-to-video generation tasks.
- Multi-Style: It includes data in multiple visual styles and can evaluate model generation capabilities under different styles.
- Camera Control: It evaluates a model's ability to follow camera trajectories, ensuring that generated scenes conform to the specified camera motion.
- 3D Consistency: It evaluates the stability of scenes in geometric structure, ensuring that generated 3D scenes remain consistent across different viewpoints.
Technical Principles of WorldScore
- Diverse Dataset: The WorldScore dataset contains multimedia data in dynamic and static configurations, suitable for image-to-video and image-to-3D tasks.
- Dynamic Configuration: It includes fields such as images, visual motion, visual style, motion type, style, camera path, objects, and prompts.
- Static Configuration: It includes fields such as images, visual motion, visual style, scene type, category, style, camera path, content list, and prompt list.
- Dataset Scale: The dataset is divided into training and test sets, with 1,000 samples in the dynamic configuration and 2,000 samples in the static configuration.
- Camera-Trajectory-Based Layout Specification: Through explicit camera-trajectory-based layout specifications, it enables unified evaluation of different methods.
- Multimodal Data Support: It supports data in multiple modalities, including images, videos, and 3D models, and is suitable for multimodal content generation tasks.
