Pipeline parallelism is essential for edge computing as it effectively consolidates the limited resources of edge devices, enabling the deployment of large Deep Neural Network (DNN) models and accelerating inference processes without compromising the performance of models. Accurate computation and communication latency estimation on heterogeneous edge devices is essential for searching for a superior parallelism plan. However, existing heterogeneous pipeline inference approaches either incur substantial resource wastage during online parallelism planning, as they utilize profiling strategies that occupy physical devices;or rely on cost models with inadequate representational capabilities, leading to inaccurate predictions, thereby harming the result of pipeline planning. This paper proposes EPipe, a novel pipeline inference framework that supports high-quality offline planning in heterogeneous edge environments. EPipe integrates two core components: the Task-Device Co-analyzer (TDC) and the Multi-pipeline Parallelism Planner (MPP). TDC utilizes an undirected connected graph to depict the compatibility of DNNs across device groups and precisely estimates inference and communication latencies through fine-grained modeling. Based on TDC, MPP utilizes a dynamic programming-based genetic algorithm to explore multi-pipeline solutions, extending beyond traditional single-pipeline methods. A comprehensive experimental evaluation on an edge testbed confirms the effectiveness of EPipe, demonstrating significant speedups in inference tasks for both task streams and single tasks. © 2024 Copyright is held by the owner/author(s).

The Video Photoplethysmography (VPPG) technique, while increasingly popular due to its convenience and cost-effectiveness, faces challenges in handling continuous head movements and vigorous motion interferences encountered in real-life scenarios. In this paper, we present a Transformer-based approach aimed at enhancing the robustness of heart rate estimation from facial videos. Leveraging the selfattention mechanism inherent in Transformers, our method adeptly captures both temporal dependencies and spatial information, thereby elevating the accuracy and resilience of heart rate estimation, even in challenging conditions. Through extensive experiments conducted on real-world face video datasets, we illustrate the effectiveness of our approach. Our results demonstrate significant improvements over existing methods in mitigating motion artifacts and enhancing the reliability of non-contact heart rate estimation in practical environments. © 2024 Copyright for this paper by its authors.

The excellent inherent contrast between biological tissues afforded by MR imaging is one of the foremost characteristics of this technique, but it depends on the scan time and hardware devices. Recent studies have shown significant progress in deep learning-based single-image super-resolution (SISR) algorithms based on MR images. Many researchers have employed implicit functions for super-resolution tasks, achieving arbitrary resolution upsampling. Nevertheless, challenges like loss of generated image texture and weak high-frequency features persist. We propose an arbitrary multiple super-resolution model based on deep residual Fourier transform and a selfattention mechanism to tackle these issues. We first use the deep Fourier residual block to construct the high and low-frequency difference of the image, compensating for the spectral bias of the multiple perceptron (MLP) network. Building upon the substantial similarity in medical image tissue structures, we add a vertical and horizontal self-attention mechanism to capture the internal correlation of features in the vertical and horizontal directions. Finally, we learn a continuous functional representation to execute super-resolution tasks at any scale. Experiment results show the effectiveness of our method on the T2 sequence of public dataset SIMON and T1, T2, and Proton Density (PD) weighted scan sequences of public dataset IXI. We conduct qualitative and quantitative comparisons of the three contrasts, illustrating the superiority of our approach. © 2023 IEEE.

In order to provide more comprehensive medical services and personalized health monitoring according to individual needs, Body Area Networks (BANs) have been extensively studied by many researchers. As BANs involve the transmission of personal private data, the security of the communication is of utmost importance. Unfortunately, existing encryption techniques cannot be directly applied with the limited power or computation ability of the sensors in BANs. An alternative direction is to use physiological signals for key agreement. However, many of the current physiological signal-based key agreement schemes either have high overheads or are vulnerable to certain security issues. In this paper, we proposed a novel secret sharing and Bloom filter based key agreement scheme that balances overhead and security for BANs. Also, we use an approximate hash table to free ourselves from the problem of dependence on the ordering of features, which has been neglected by previous researchers. We validate the security of our scheme with based on real datasets and compare overheads with other solutions. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Long-tail learning primarily focuses on mitigating the label distribution shift between long-tailed training data and uniformly distributed test data. However, in real-world applications, we often encounter a more intricate challenge where the test label distribution is agnostic. To address this problem, we first theoretically establish the substantial potential for reducing the generalization error if we can precisely estimate the test label distribution. Motivated by the theoretical insight, we introduce a simple yet effective solution called label shift correction (LSC). LSC estimates the test label distribution within the proposed framework of generalized black box shift estimation, and adjusts the predictions from a pre-trained model to align with the test distribution. Theoretical analyses confirm that accurate estimation of test label distribution can effectively reduce the generalization error. Extensive experimental results demonstrate that our method significantly outperforms previous state-of-the-art approaches, especially when confronted with non-uniform test label distribution. Notably, the proposed method is general and complements existing long-tail learning approaches, consistently improving their performance.

Person Re-Identification (ReID) is a crucial task in computer vision that aims to match persons captured from non-overlapping camera views. In this paper, to alleviate the impacts of background and occlusion, we propose to use instance segmentation and pose estimation methods to create masks for global feature extraction. Furthermore, we divide the pedestrian images into three regions according to pedestrian keypoints, trying to eliminate the alignment errors. This part-based matching strategy also helps to address the occlusion issue. Overall, we construct a deep learning network with three branches, including two global branches and a part-based branch. The two global branches extract global features using segmentation-based mask and the mask derived from pedestrian keypoint heatmaps, respectively. In the end, a weighted fusion strategy is used to combine the global scores and part-based scores for final classification. This network enables us to acquire robust global feature of pedestrians by excluding background and occlusion, and simultaneously address the alignment errors to some extent. Experimental results on these three widely used datasets demonstrate the effectiveness of our method: Specifically, it achieves 64.5% rank-1 accuracy and 54.3% mAP on Occluded-Duke, and 94.4% and 87.1% rank-1 accuracies on Market-1501 and DukeMTMC-reID, respectively. © 2023 IEEE.

The emerging edge-cloud computing paradigm, comprising cloud centers and multiple distributed edge servers, extends the computing capability from the cloud center to a range of servers. Although the microservice autoscaling problem has been intensively studied in the context of cloud computing, existing algorithms in most cases cannot be effectively migrated to the edge-cloud environment because servers are geographically distributed and heterogeneous, and information is not synchronized between servers. Existing works, however, mainly focus on centralized strategies with time-consuming synchronization methods, i.e. strategies shared by all servers, without comprehensively considering the heterogeneity and distribution of the environment. Soft information synchronization, autonomy and collaboration is proposed to tackle the aforementioned issues, and refer to it as SAC paradigm. According to the SAC paradigm, each server with inferred information of other servers can collaborate with others by a dedicated autoscaling strategy, that is, server collaboration. The microservice autoscaling problem is then transformed into the Graph-based Jointly Microservice Autoscaling (GJMA) problem based on spectral graph theory. GJMA problem aims to minimize average waiting time of microservice-based application while reducing service-level agreement(SLA) violation rate and fluctuations in the autoscaling process, taking into account resource heterogeneity. Graph-based Multi-agent Algorithm(GMA), an implementation of SAC paradigm based on graph convolutional networks and multi-agent reinforcement learning, is implemented to solve GJMA problem. Experimental results show that the proposed algorithm for the edge-cloud environment is always efficient to find a better autoscaling strategy compared to the implemented comparison algorithms. © 2023 IEEE.

Ultrasound images are widely used because they are easy to use and non-invasive. However, differences in acquisition equipment and frequency settings can result in varying image quality. To address this issue, we propose an ultrasound image enhancement method based on spatially variable neural implicit networks. Our approach consists of several steps: First, the encoder of an arbitrary-scale super-resolution network processes low-quality ultrasound images to generate a feature matrix. Concurrently, the parameter generation network decomposes the low-quality image into a parameter matrix. The pixel prediction module of the arbitrary-scale super-resolution network then uses the parameter matrix to map encoded features to pixel values. To further align the predicted pixel values with the distribution of high-quality ultrasound images and reduce interference from artifacts, we design a spectrum discriminator network based on the fast Fourier transform. This network is highly effective at capturing high-quality information and minimizing the impact of redundant information. In both qualitative and quantitative comparisons with current state-of-the-art image enhancement methods and arbitrary magnification techniques, our approach demonstrates superior performance. © 2024 IEEE.
