To find out the feasibility of different neural networks in sEMG-based force estimation, this paper, three types networks, namely convolutional network (CNN), long short-term memory (LSTM) and their combination (C-LSTM) were applied to predict muscle generated static isometric elbow flexion across circumstances (multi-subject, subject-dependent subject-independent). Eight healthy men recruited for experiments, results demonstrated that all models applicable LSTM C-LSTM achieved better...

Studies have shown deep neural networks (DNN) as a potential tool for classifying dysarthric speakers and controls. However, representations used to train DNNs are largely not clinically interpretable, which limits clinical value. Here, model with bottleneck layer is trained jointly learn classification label four clinically-interpretable features. Evaluation of two dysarthria subtypes shows that the proposed method can flexibly trade-off between improved accuracy discovery deficit patterns....

We will introduce artificial intelligence solutions education. use technology for classroom behavior analysis improve practice courses' effectiveness. In an instructional milieu, image acquisition tools such as cameras...

Abstract Background Health-related quality of life (HRQOL) in cancer patients has attracted increasing attention, which may be associated with self-rated health (SRH), anxiety, and depression. However, limited studies have focused on the mediating role anxiety depression relationship between SRH HRQOL among patients. Therefore, this study aims to explore serial multiple effects Methods This cross-sectional investigated a total 565 hospitalized Anhui province China from November 2020 October...

To alleviate the negative impacts of muscle fatigue on a force estimation model, modification framework taking use index was put forward in this paper. Muscle and surface electromyography were first collected using high-density electrode grid dynamometer. Then, multi-step signal pre-processing nonnegative matrix factorization-based optimization conducted, with indices being extracted same time. Next, degree 4 polynomial fitting model employed to undertake training process, relationship...

A common assumption in stereo matching is that the corresponding pixels images have similar pixel values. Unfortunately, such an may not be true due to radiometric variations different views, leading severely degraded results. In this letter, we propose a radiometrically invariant algorithm called Optimal Local Adaptive Radiometric Compensation (LARAC). LARAC, approximate spatially varying Pixel Value Correspondence Function (PVCF) between pair as locally consistent polynomial within optimal...

The emerging cloud gaming technology has been growing fast, driving up huge mobile consumer demands. video streaming based scenario renders the game scenes in servers, and streams encoded sequences to thin clints where are decoded displayed players. However, current existing clouding services have some problems, such as latency bandwidth limitation. size of stream is usually quite large which requires heavy transmission. Worse still, frame data rate will burst when contain fast translation...

In this paper, we propose a virtual 3D Eyeglasses Try-on (3DET) system, with efficient, realistic and real-time augmented performance.

In this paper, we present a novel view synthesis method named Visto, which uses reference input to generate synthesized views in nearby viewpoints. We formulate the problem as joint optimization of inter-view texture and depth map similarity, framework that is significantly different from other traditional approaches. As such, Visto tends implicitly inherit image characteristics without explicit use priors or modeling. assumes each patch available both thus can be applied common area between...
