Rotated object detection aims to identify and locate objects in images with arbitrary orientation. In this scenario, the oriented directions of vary considerably across different images, while multiple orientations exist within an image. This intrinsic characteristic makes it challenging for standard backbone networks extract high-quality features these arbitrarily orientated objects. paper, we present Adaptive Convolution (ARC) module handle afore-mentioned challenges. our ARC module,...
Cross domain object detection is a realistic and challenging task in the wild. It suffers from performance degradation due to large shift of data distributions lack instance-level annotations target domain. Existing approaches mainly focus on either these two difficulties, even though they are closely coupled cross detection. To solve this problem, we propose novel Target-perceived Dual-branch Distillation (TDD) framework. By integrating branches both source domains unified teacher-student...
Attribute recognition is a crucial but challenging task due to viewpoint changes, illumination variations and appearance diversities, etc. Most of previous work only consider the attribute-level feature embedding, which might perform poorly in complicated heterogeneous conditions. To address this problem, we propose hierarchical embedding (HFE) framework, learns fine-grained by combining attribute ID information. In HFE, maintain inter-class intra-class simultaneously. Not samples with same...

<title>Abstract</title> Antiferromagnetism has become a promising candidate for the next generation electronic devices due to its thermal stability, low energy consumption, and fast switching speed. However, canceling of net magnetic moment in antiferromagnetic order presents great challenge on quantitative characterization modulation, hindering investigation application. In this work, utilizing optical second harmonic (SHG) wide temperature range, integrated differential phase contrast...
Electroencephalography (EEG) can reveal the abnormalities of dopaminergic subcortico-cortical circuits in patients with Parkinson's disease (PD). However, conventional time-frequency analysis EEG signals cannot fully non-linear processes neural activities and interactions. A novel Holo-Hilbert Spectral Analysis (HHSA) was applied to features resting state 99 PD 59 healthy controls (HCs). demonstrated a reduction β bands frontal central regions, γ central, parietal, temporal regions.

Large scale surveillance video analysis is one of the most important components in future artificial intelligent city. It a very challenging but practical system, consists multiple functionalities such as object detection, tracking, identification and behavior analysis. In this paper, we try to address three tasks hosted NVIDIA AI City Challenge contest. First, system that transforming image coordinate world has been proposed, which useful estimate vehicle speed on road. Second, anomalies...
The purpose was to examine and compare the longer-term generalization between 2 different practice dosages for a single-session treadmill slip-perturbation training when reexposed an overground slip 6 months later. A total of 45 older adults were conveniently assigned either 24 or 40 slip-like perturbation trials third control group. Overground slips given immediately after initial training, at in order immediate effects. performance (center mass stability vertical limb support) fall...
This study examined the effects of perturbation training on contextual interference and generalization encountering a novel opposing perturbation. One hundred sixty-nine community-dwelling healthy older adults (69.6 ± 6.4 years) were randomly assigned to one three groups: slip-perturbation (St, n = 67) group received 24 slips, trip-perturbation (Tt, trips, control (Ctrl: 31) only non-perturbed walking trials ( ClinicalTrials.gov NCT03199729; https://clinicaltrials.gov/ct2/show/NCT03199729 )....
The task of cross-modal image retrieval has recently attracted considerable research attention. In real-world scenarios, keyword-based queries issued by users are usually short and have broad semantics. Therefore, semantic diversity is as important accuracy in such user-oriented services, which improves user experience. However, most typical methods based on single point query embedding inevitably result low diversity, while existing diverse approaches frequently lead to due a lack...
Slip-induced falls are a growing health concern for older adults, and near-fall events associated with an increased risk of falling. To detect adults at high slip-related falls, this study aimed to develop models event detection based on accelerometry data collected by body-fixed sensors. Thirty-four healthy who experienced 24 laboratory-induced slips were included. The slip outcomes first identified as loss balance (LOB) no LOB (NLOB), then the kinematic measures compared between these two...
Slip outcomes are categorized as either a backward loss of balance (LOB) or no (no-LOB) in which an individual does not take step to regain their stability. LOB includes falls and nonfalls, while no-LOB skate overs walkovers. Researchers uncertain about factors determine slip at critical instants they do so. The purpose the study was investigate affecting proactive early reactive phases by analyzing 136 trials from 68 participants (age: 72.2 [5.3] y, female: 22). Segment angles average joint...
Text coherence plays a key role in document quality assessment. Most existing text methods only focus on similarity of adjacent sentences. However, local exists sentences with broader contexts and diverse rhetoric relations, rather than just similarity. Besides, the highlevel is also an important aspect quality. To this end, we propose hierarchical model for In our model, implement attention mechanism to capture location semantics, bilinear tensor layer measure max-coherence pooling...
Oriented object detection, an emerging task in recent years, aims to identify and locate objects across varied orientations. This requires the detector accurately capture orientation information, which varies significantly within images. Despite existing substantial efforts, simultaneously ensuring model effectiveness parameter efficiency remains challenging this scenario. In paper, we propose a lightweight yet effective Group-wise Rotating Attention (GRA) module replace convolution...
