To solve the problem of slow diagnosis speed of kiwifruit foliar surface diseases and insufficient diagnosis ability of small target diseases, a lightweight network model based on YOLOv4-Tiny is proposed. Firstly, by introducing a depthwise separable convolution at the end of the backbone network, the number of parameters is reduced while the accuracy of diagnosis is guaranteed, and the training and diagnosis speed is improved. Secondly, SPP-Net is introduced in the Neck to realize the fusion of multiple receptive fields and the aggregation of multi-scale information, thereby improving the diagnostic accuracy of the model. Lastly, the multi-feature fusion FPN model is modified to improve the diagnosis ability of small target diseases, and then improve the diagnosis accuracy. The experimental results show that our method is superior to YOLOv4-Tiny on mAP@O.5, diagnosis speed, model size and small target disease diagnosis ability.
针对猕猴桃叶面病害诊断速度慢、小目标病害诊断能力不足的问题,提出了一种基于YOLOv4-Tiny的轻量级网络模型。首先,通过在骨干网末端引入深度可分卷积,在保证诊断精度的同时减少了参数的数量,提高了训练和诊断速度;其次,在颈部引入SPP-Net,实现了多个感受野的融合和多尺度信息的聚合,从而提高了模型的诊断准确率;最后,对多特征融合FPN模型进行改进,提高对小靶点疾病的诊断能力,进而提高诊断准确率。实验结果表明,该方法在mAP@O.5、诊断速度、模型大小和小靶点疾病诊断能力等方面均优于YOLOv4-Tiny。

For the “LifeAfter” survival game problem, in order to make it smooth customs clearance, players need to meet multiple conditions, so the survival problem is abstracted into the path planning problem under multiple constraints. Aiming at this problem, we create A-D algorithm based on heuristic A * algorithm and Dijkstra algorithm. In order to reduce the complexity of computer calculation, we greatly improve the operation efficiency of the algorithm by the method of space exchange time. For the three problems in the topic, we propose three different benefit functions to optimize the global, avoid falling into the local optimal solution, guide the player under the constraints of multiple conditions, as far as possible to make the objective function value the largest (respectively: the least supply point (the sum of campfire point and food point), the path, the end point of satiation and comfort is the largest).
对于“LifeAfter”生存博弈问题,为了使其顺利通关,玩家需要满足多个条件,因此将生存问题抽象为多个约束条件下的路径规划问题。针对这一问题,我们基于启发式A *算法和Dijkstra算法创建了A- d算法。为了降低计算机计算的复杂性,我们通过空间交换时间的方法大大提高了算法的运行效率。针对课题中的三个问题,我们提出了三种不同的效益函数进行全局优化,避免陷入局部最优解,引导玩家在多重条件约束下,尽可能使目标函数值最大(分别为:供给点最小(营火点和食物点之和)、路径、饱足和舒适度终点最大)。

Aiming at the contradiction between accuracy and speed in industrial object detection, this paper proposes an industrial object detection method based on improved CenterNet. The improved method uses ResNet-50 as the Backbone to boost detection speed, and an upsampling layer is added to the feature processing network to improve detection accuracy. The expermient results show that the mAP of the improved method reaches 87.41 %, which is 3.44% higher than the CenterNet-Res101 method, and the detection speed reaches 31 FPS, which is 4 FPS faster than the CenterNet-Res101 method.

The synchronization between wireless sensor nodes represents a big issue in all low-cost systems in which each node performs measurements using its own sensors and stores locally the measured values. In this paper, we will analyze in detail the implementation limits concerning the simplest synchronization strategy that can be implemented for Wireless Sensor Networks (WSNs). In fact, we consider a type of star network in which a master periodically sends a synchronization message to the slaves belonging to its own subnet. The considerations made are referred to commercial low-cost microprocessors and System-on-Chips (SoCs). Solutions too simplistic lead to large synchronization errors or excessive power consumption; correct approaches require continuous calibration by the slaves and are therefore impractical.
在所有低成本系统中,无线传感器节点之间的同步是一个大问题,在这些系统中,每个节点使用自己的传感器进行测量,并在本地存储测量值。在本文中,我们将详细分析可用于无线传感器网络(WSNs)的最简单同步策略的实现限制。实际上,我们考虑的是一种星型网络,其中主节点周期性地向属于自己子网的从节点发送同步消息。所做的考虑是指商业低成本微处理器和系统芯片(soc)。过于简单的解决方案会导致大的同步错误或过度的功耗;正确的方法需要从机连续校准,因此不切实际。

In the process of image imaging, replication, scanning, transmission and display, image degradation will inevitably occur, such as image blurring, noise interference, etc. In the field of medical image application, clear and high-quality images are needed. Therefore, medical image restoration is of great significance. In view of the fact that the current popular image restoration algorithms are less than ideal, this paper proposes an improved non-local mean filtering algorithm based on medical image restoration. This algorithm firstly adopts the norm LO gradient minimization restoration algorithm to restore the smooth part of the image, then adopts the wave-atom transformation to restore the detail part of the image, and finally adopts the improved non-local mean filtering to deal with the ringing effect and false edge generated by wave-atom transformation. The algorithm experiment was carried out on MATLAB R2009a platform. The experimental results show that the restoration algorithm has certain improvement in both subjective and objective effects of image restoration compared with the current popular image restoration algorithm.
在图像的成像、复制、扫描、传输和显示过程中,不可避免地会出现图像退化,如图像模糊、噪声干扰等。在医学图像应用领域,需要清晰、高质量的图像。因此,医学图像的恢复具有重要的意义。针对目前流行的图像恢复算法不太理想的问题,提出了一种改进的基于医学图像恢复的非局部均值滤波算法。该算法首先采用范数LO梯度最小化恢复算法恢复图像的光滑部分,然后采用波原子变换恢复图像的细节部分,最后采用改进的非局部均值滤波处理波原子变换产生的振铃效应和假边缘。算法实验在MATLAB R2009a平台上进行。实验结果表明,与目前流行的图像恢复算法相比,该恢复算法在图像恢复的主客观效果上都有一定的提高。

Pub Date : 2021-08-01 DOI: 10.1109/ICCEAI52939.2021.00071

In recent years, with the development of heart sound classification technology, it has played an important role in the detection of congenital heart disease. However, in the traditional heart sound classification tasks, they are all two classification tasks. However, the heart sound signals are actually collected from five different locations during the collection process. Before we classify the normal and abnormal heart sounds, we should carry out the multi-classification task of the mixed heart sound signals in the collection area. In this paper, Mel cepstrum coefficient and power spectral density are taken as data sets for machine learning. We are committed to finding the best classification results, so we set two different labels, one is the multi-classification task of the location of heart sound signal acquisition area, and the other is the two-classification task of normal and abnormal heart sound signals. The accuracy rate.recall rate and F1 rate of heart sound signal recognition after subarea can reach 92.92%, 91.56% and 94.04%, which provides reference for clinical heart sound classification.
近年来,随着心音分类技术的发展,它在先天性心脏病的检测中发挥了重要作用。然而,在传统的心音分类任务中,它们都是两个分类任务。然而,在采集过程中,心音信号实际上是从五个不同的位置采集的。在对正常心音和异常心音进行分类之前,我们应该对采集区域的混合心音信号进行多重分类任务。本文将Mel倒谱系数和功率谱密度作为机器学习的数据集。我们致力于寻找最好的分类结果,所以我们设置了两个不同的标签,一个是心音信号采集区域位置的多重分类任务,另一个是正常和异常心音信号的双分类任务。正确率。分区后心音信号识别的召回率和F1率分别达到92.92%、91.56%和94.04%,为临床心音分类提供参考。

However, in the traditional heart sound classification tasks, they are all two classification tasks. However, the heart sound signals are actually collected from five different locations during the collection process. Before we classify the normal and abnormal heart sounds, we should carry out the multi-classification task of the mixed heart sound signals in the collection area. In this paper, Mel cepstrum coefficient and power spectral density are taken as data sets for machine learning. We are committed to finding the best classification results, so we set two different labels, one is the multi-classification task of the location of heart sound signal acquisition area, and the other is the two-classification task of normal and abnormal heart sound signals. The accuracy rate.recall rate and F1 rate of heart sound signal recognition after subarea can reach 92.92%, 91.56% and 94.04%, which provides reference for clinical heart sound classification.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128221469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
