In daily life, there are a variety of complex sound sources. It is important to effectively detect certain sounds in some situations. With the outbreak COVID-19, it necessary distinguish coughing, estimate suspected patients population. this paper, we propose method for cough recognition based on Mel-spectrogram and Convolutional Neural Network called Cough Recognition (CRN), which can sounds.
In the field of disease diagnosis where only a small dataset medical images may be accessible, light-weight convolutional neural network (CNN) has become popular because it can help to avoid over-fitting problem and improve computational efficiency. However, feature extraction capability CNN is inferior that heavy-weight counterpart. Although attention mechanism provides feasible solution this problem, existing modules, such as squeeze excitation module block module, have insufficient...
Onboard real-time object detection in remote sensing images is a crucial but challenging task this computation-constrained scenario. This not only requires the algorithm to yield excellent performance also requests limited time and space complexity of algorithm. However, previous convolutional neural networks (CNN) based detectors for suffer from heavy computational cost, which hinders them being deployed on satellites. Moreover, an onboard detector desired detect objects at vastly different...
The predicted capacity gain of a traditional co- located MIMO system is often severely limited in realistic propagation scenarios, especially when the number antennas becomes large. Recently, generalized paradigm for multiple-antenna communications, distributed MIMO, proposed as remedy. In this paper, through asymptotic large-system analysis, we provide solid justifications on advantages over co-located communication channels are subject to spatial correlation and shadow fading. We also...

Three-dimensional (3D) medical image segmentation typically demands extensive labeled training samples, which is prohibitively time-consuming and requires significant expertise. Although this demand can be mitigated by special learning paradigms such as semi-supervised learning, the cost still high due to reader-unfriendly 3D data structure. In paper, we seek a solution of robust using extremely simplified annotation that delineates only single slice per each volume for subset samples. To...

Optical coherence tomography (OCT) has found wide application to the diagnosis of ophthalmic diseases, but quality OCT images is degraded by speckle noise. The convolutional neural network (CNN) based methods have attracted much attention in image despeckling. However, these generally need noisy-clean pairs for training and they are difficult capture global context information effectively. To address issues, we proposed a novel unsupervised despeckling method. This method uses cross-scale...
This Letter presents a guided filtering (GF)-based nonlocal means (NLM) method for despeckling of optical coherence tomography (OCT) images.

The boosting iterative strategies are further incorporated ensure performance. Experiments on real OCT images demonstrate our...

Visual objects are recognized by their features. Whereas some features based on simple components (i.e., local features, such as orientation of line segments), the whole object global an having a hole in it). Over past five decades, behavioral, physiological, anatomical and computational studies have established general model vision, which starts from extracting lower visual pathways followed feature integration process that extracts higher pathways. This local-to-global is successful...
