Many keypoint detection and description methods have been proposed for image matching or registration. While these demonstrate promising performance single-modality matching, they often struggle with multimodal data because the descriptors trained on tend to lack robustness against non-linear variations present in data. Extending such requires well-aligned learn modality-invariant descriptors. However, acquiring is costly impractical many real-world scenarios. To address this challenge, we...

Drones have become prevalent robotic platforms with diverse applications, showing significant potential in Embodied Artificial Intelligence (Embodied AI). Referring Expression Comprehension (REC) enables drones to locate objects based on natural language expressions, a crucial capability for AI. Despite advances REC ground-level scenes, aerial views introduce unique challenges including varying viewpoints, occlusions and scale variations. To address this gap, we RefDrone, benchmark drone...

Large Language Models (LLMs) are progressively being utilized as machine learning services and interface tools for various applications. However, the security implications of LLMs, particularly in relation to adversarial Trojan attacks, remain insufficiently examined. In this paper, we propose TrojLLM, an automatic black-box framework effectively generate universal stealthy triggers. When these triggers incorporated into input data, LLMs' outputs can be maliciously manipulated. Moreover,...

This paper proposes a novel method for image magnification by exploiting the property that intensity of an varies along direction gradient very quickly. It aims to maintain sharp edges and clear details. The proposed first calculates low-resolution fitting surface with quadratic polynomial precision. Then, bicubic interpolation is used obtain initial gradients high-resolution (HR) image. are readjusted find constrained HR image, according spatial correlations between within local window. To...

Part of important structural edges in the image is smoothed due to small gradients, while others are preserved with greater gradients. Therefore, authors propose a two‐stage smoothing method based on edge‐patch histogram equalisation and patch decomposition. The authors' purpose increase gradient reducing texture region. they divide into edge‐patches where concentrated or non‐edge‐patches details by segmentation. needs be equalised histograms for increasing edge pixels. All patches...
