首个可控虚化渲染挑战赛，8支团队提交有效方案。
The First Controllable Bokeh Rendering Challenge at NTIRE 2026
- 基于Bokehlicious方法改进，实现可控虚化效果。
- 在未见图像上评估，针对人像与复杂场景优化。
- 结合定量指标与专家主观评价，全面衡量质量。
本研究呈现了首届NTIRE 2026可控虚化渲染挑战赛的成果，展示了最具成效的参赛方法。共有44名参与者注册，最终8支队伍提交了有效解决方案。所有提交结果均在未见过的图像上进行评估，重点关注人像及具有复杂且视觉吸引人的虚化效果的场景。除第一赛道采用既定量化保真度指标外，第二赛道还组织了专家小组开展定性用户研究，用于感知评估。由于这是该主题的首次挑战，多数参赛者聚焦于对Bokehlicious基线方法的优化与扩展。
原文摘要 · Abstract (English)
This study presents the outcomes of the first Controllable Bokeh Rendering Challenge at NTIRE and highlights the most effective submitted methodologies. In total, 44 participants registered for the competition, of which 8 teams submitted valid solutions after the conclusion of the final test phase. All submissions were evaluated on unseen images, focusing on portraits and intricate subjects with complex and visually appealing bokeh phenomena. In addition to the first track focusing on established quantitative fidelity metrics, we conducted a qualitative user study with a panel of experts for a second track focusing on perceptual assessment. As this was the inaugural challenge on this topic, most of the participants focused on refining and extending the Bokehlicious baseline method.
