Revolutionizing Image Generation: Bridging Composition and Distinction with Scone
Scone proposes a unified understanding-generation model with an 'understanding bridge strategy'. This involves a two-stage training: first for composition on single-candidate data, then for distinction enhancement via semantic alignment and attention-based masking. The understanding expert guides the generation expert to preserve identity and minimize interference without adding extra parameters.
Executive Impact at a Glance
This analysis focuses on 'Scone', a novel method for subject-driven image generation that unifies composition and distinction, addressing limitations in complex visual contexts. It introduces an 'understanding bridge strategy' and the 'SconeEval' benchmark, demonstrating superior performance in accurately generating target subjects amidst multiple candidates.

Current Limitations: Lack of Distinction
Subject-driven image generation has advanced significantly, handling multi-subject composition. However, it often fails at 'distinction' – correctly identifying and generating a target subject when multiple candidates are present in a reference image. This leads to issues like subject omissions or misidentification, particularly in complex, real-world visual settings (Fig. 1a). Current models, while capable of combining subjects, struggle to parse intricate details and interference from reference images, limiting their practical performance.

Unified Understanding-Generation Modeling
Scone integrates composition and distinction through a unified understanding-generation framework. It leverages the understanding expert as a 'semantic bridge' to convey high-level semantic information and guide the generation expert. This ensures subject identity preservation and minimizes interference from irrelevant content. The model uses a two-stage training scheme: first for composition, then for distinction enhancement via semantic alignment and attention-based masking.

Comprehensive Evaluation for Distinction
SconeEval is a new benchmark designed to assess a model's ability to distinguish and generate referred subjects in complex visual contexts. Unlike traditional benchmarks that focus on composition and visual fidelity, SconeEval includes tasks with varying difficulty: composition, distinction, and distinction & composition. It covers cross-category and intra-category cases, providing a more realistic and rigorous evaluation of subject-driven image generation methods (Fig. 4). This benchmark helps address the limitations of existing evaluation methods which often simplify contexts and rely on average similarity metrics, failing to capture issues like subject omission or redundancy.

Test Cases Across Diverse Scenarios
Real-World Challenge: Multi-Candidate Distinction
Imagine a reference image containing 'a brown dog, a white cat, and a black bird.' The instruction asks to 'generate the white cat playing with a ball.' Traditional models might struggle to isolate the 'white cat' from the other animals, potentially generating the wrong animal or a generic cat. Scone, with its distinction capabilities, is designed to correctly identify the 'white cat' and generate it as specified, demonstrating its superiority in complex multi-candidate scenarios (Fig. 1a, Scone example). This scenario highlights the critical need for robust distinction, which SconeEval directly assesses.
