FAHCD-Net: Frequency-Adaptive Heatmap-Conditional Diffusion Networks for Robust Facial Landmark Detection

Facial Landmark Detection(FLD) is a crucial task in various applications and has achieved significant advancements in recent years. However, current FLD methods still struggle under challenging conditions, where facial structural variations, information loss, and noise interference severely compromise the integrity and...

SkillIR: Evolving Scene-Aware Skills for Agentic Image Restoration

SkillIR is proposed, a skill-guided framework that represents restoration experience as degradation-centered action evidence rather than complete tool-use trajectories rather than complete tool-use trajectories and improves restoration quality and enables more reliable and effective tool use.

FreqFLD: Towards all-in-one facial landmark detection via frequency modulation.

FreqFLD, a frequency-modulated framework towards All-in-One facial landmark detection, introduces a Frequency Modulation Module (FreqMoM) to explicitly induce the frequency prior by decoupling and modulating low- and high-frequency components, which is then injected into subsequent feature modeling to enable balanced m...
