Foundation Models (FMs) have demonstrated strong generalization across diverse vision tasks. However, their deployment in federated settings is hindered by high computational demands, substantial communication overhead, and significant inference costs. We propose DSFedMed, a dual-scale federated fra
One-shot federated learning (OSFL) reduces the communication cost and privacy risks of iterative federated learning by constructing a global model with a single round of communication. However, most existing methods struggle to achieve robust performance on real-world domains such as medical imaging
Physiological signals such as EEG, ECG, and PPG are widely used in clinical monitoring. Recent self-supervised learning (SSL) methods offer an attractive way to leverage unlabeled recordings, yet they still fall short in practice. In particular, current SSL methods struggle across heterogeneous data
Autofocus (AF) is essential for imaging systems, particularly in industrial applications such as automated optical inspection (AOI), where achieving precise focus is critical. Conventional AF methods rely on peak-searching algorithms that require dense focal sampling, making them inefficient in smal…
Recently, numerous robust image hashing schemes have been developed for content identification. However, many of these schemes face the challenges of maintaining discrimination while simultaneously resisting large-scale attacks. In this paper, we propose a robust image hashing scheme based on Contra…
Spiking Neural Networks are celebrated for energy efficiency and biological plausibility. Building on Spiking Self-Attention (SSA), Spiking Transformers are extensively studied due to their exceptional performance. However, SSA focuses solely on spatial dimension at each time step, overlooking the c…
Spiking Neural Networks (SNNs), due to their unique spike-based inference mechanism, offer low power consumption and biological plausibility. As a fundamental technology for various real-world applications, 3D point cloud analysis faces significant challenges related to high computational overhead a…
Human evaluation is viewed as a reliable evaluation method for NLG which is expensive and time-consuming. To save labor and costs, researchers usually perform human evaluation on a small subset of data sampled from the whole dataset in practice. However, different selection subsets will lead to diff…
Unsupervised Domain Adaptation (UDA) deals with transferring knowledge from labeled source domains to unlabeled target domains. This addresses the challenge of different distributions across domains, commonly known as domain shift. Numerous methods attempt to align distributions across domains while…
Spiking Neural Networks (SNNs) provide a sparse spike-driven mechanism which is believed to be critical for energy-efficient deep learning. Mixture-of-Experts (MoE), on the other side, aligns with the brain mechanism of distributed and sparse processing, resulting in an efficient way of enhancing m…
Vector font synthesis is a challenging and ongoing problem in the fields of Computer Vision and Computer Graphics. The recently-proposed DeepVecFont achieved state-of-the-art performance by exploiting information of both the image and sequence modalities of vector fonts. However, it has limited capa…
Synthesis-based steganography without embedding (SWE) methods transform secret messages to container images synthesised by generative networks, which eliminates distortions of container images and thus can fundamentally resist typical steganalysis tools. However, existing methods suffer from weak me…
We consider two biologically plausible structures, the Spiking Neural Network (SNN) and the self-attention mechanism. The former offers an energy-efficient and event-driven paradigm for deep learning, while the latter has the ability to capture feature dependencies, enabling Transformer to achieve g…
This paper introduces a deep model watermark with an irreversible ownership verification scheme: Trapdoor Normalization (TdN), inspired by the trapdoor function in traditional cryptography. To protect intellectual property within deep models, the proposed method is able to embed ownership informatio…
Fake news brings us panic and misunderstanding against the truth, especially under some unusual circumstances, such as the outbreak of COVID-19. It’s crucial to detect fake news on social media early to avoid further propagation. Previous methods manually label the stances implied in post-reply pair…
Recent attention-based image inpainting methods have made inspiring progress by propagating distant contextual information into holes. However, they tend to generate blurry contents since the propagation process is always misled by preliminarily-recovered holes features which are not well-inferred.…
Deep neural networks (DNNs) are considered as intellectual property of their corresponding owners and thus are in urgent need of ownership protection, due to the massive amount of time and resources invested in designing, tuning and training them. In this paper, we propose a novel watermark-based ow…
Semantic segmentation is a challenging task for computer vision which aims to classify the objects from the pixel level. Previous methods based on deep learning have made some progress but the labeling work is very time-consuming. Few-shot semantic segmentation can alleviate this problem. In this pa…
Video inpainting aims to synthesize visually pleasant and temporally consistent content in missing regions of video. Due to a variety of motions across different frames, it is highly challenging to utilize effective temporal information to recover videos. Existing deep learning based methods usually…
Feature extraction and label estimation are critical in unsupervised person re-identification (re-ID). Most previous works focus on acquiring high-layer semantic features and reckon without the lower-layer details lost in the learning process, which causes the extracted features to be less comprehen…
The depth image based rendering (DIBR) plays a key role in 3D video synthesis, by which other virtual views can be generated from a 2D video and its depth map. However, in the synthesis process, the background occluded by the foreground objects might be exposed in the new view, resulting in some hol…
