The perception of drones, also known as Unmanned Aerial Vehicles (UAVs), particularly in infrared videos, is crucial for effective anti-UAV tasks. However, existing datasets UAV tracking have limitations terms target size and attribute distribution characteristics, which do not fully represent complex realistic scenes. To address this issue, we introduce a generalized benchmark called <bold xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Robust 3D perception amidst corruption is a crucial task in the realm of vision. Conventional data augmentation methods aimed at enhancing robustness typically apply random transformations to all point cloud samples offline, neglecting sample structure, which often leads over- or under-enhancement. In this study, we propose an alternative approach address issue by employing sample-adaptive based on through auto-augmentation framework named AdaptPoint++. Central imitator, initiates with...

Discriminative correlation filter (DCF)-based methods have demonstrated superior performance in UAV tracking via fusing multiple types of features and updating models online. However, most DCF-based trackers simply cascade different features, failing to fully take advantage their complementary strength. In addition, online update strategies are limited using a single fixed learning rate, which often leads model degradation when suffering challenges. this paper, we present an Auto-Perceiving...

The tracking performance of discriminative correlation filters (DCFs) is often subject to unwanted boundary effects. Many attempts have already been made address the above issue by enlarging searching regions over last years.

Most existing tracking methods based on discriminative correlation filters (DCFs) update the tracker every frame with a fixed learning rate. However, constantly adjusting can hardly handle fickle target appearance in UAV (e.g., undergoing partial occlusion, illumination variation, or deformation). To mitigate this, we propose novel auto-learning filter for tracking, which fully exploits valuable information behind response maps adaptive feedback updating. Concretely, first introduce...
