      <title>Create anything anywhere: Layout-controllable personalized diffusion model for multiple subjects</title>
      <link>https://vilab.team/publication/create-anything-anywhere-layout-controllable-personalized-di/</link>

      <guid>https://vilab.team/publication/create-anything-anywhere-layout-controllable-personalized-di/</guid>
      <description>&lt;p&gt;Diffusion models have significantly advanced text-to-image generation, laying the foundation for the development of personalized generative frameworks. However, existing methods lack precise layout controllability and overlook the potential of dynamic features of reference subjects in improving fidelity. In this work, we propose Layout-Controllable Personalized Diffusion (LCP-Diffusion) model, a novel framework that integrates subject identity preservation with flexible layout guidance in a tuning-free approach. Our model employs a Dynamic-Static Complementary Visual Refining module to comprehensively capture the intricate details of reference subjects, and introduces a Dual Layout Control mechanism to enforce robust spatial control across both training and inference stages. Extensive experiments validate that LCP-Diffusion excels in both identity preservation and layout controllability. To the best of our …&lt;/p&gt;

      <title>Enhancing Visual Tracking by Leveraging High-frequency Information within Event Signals</title>
      <link>https://vilab.team/publication/enhancing-visual-tracking-by-leveraging-high-frequency-infor/</link>
      <pubDate>Wed, 01 Jan 2025 00:00:00 +0000</pubDate>
      <guid>https://vilab.team/publication/enhancing-visual-tracking-by-leveraging-high-frequency-infor/</guid>
      <description>&lt;p&gt;Traditional object trackers struggle in degraded scenarios, lacking sufficient appearance details of moving targets for precise tracking. Recent trackers have integrated highfrequency event signals to assist tracking. However, they neglect the high-temporalresolution motion information inherent in events, limiting their performance especially in occlusion and background clutter. To address these challenges, we propose HFTrack, a novel tracker designed to fully leverage the spatio-temporal high-frequency information within event signals, thereby enhancing the tracking performance. Specifically, we introduce a frequency-based feature enhancement module, which enriches the frame feature with high-frequency components from events in frequency space, capturing detailed appearance information of moving targets. Additionally, we propose a spatio-temporal information decoder with an auto-regressive temporal query, integrating both historical motion cues from events and enhanced spatial features for robust target localization. Experimental results demonstrate that our HFTrack significantly outperforms existing trackers, showcasing its strong ability to track the target under challenging conditions.&lt;/p&gt;
