In recent years, with the development of sensor technology and edge computing, new possibilities for dance posture training have been provided. The aim of this study is to develop a temperature sensor and edge detection algorithm based on thermal energy consumption optimization to improve the efficiency and accuracy of dance pose training. Wearable devices containing high-precision temperature sensors are able to monitor temperature changes in various parts of the dancer's body in real time. Through wireless transmission technology, this data is sent to edge computing devices for processing. edge computing devices use edge detection algorithms to quickly analyze a dancer's thermal consumption patterns and identify which postures or movements are causing excessive energy consumption. The results show that the temperature sensor and the edge detection algorithm can effectively monitor and analyze the dancers' thermal energy consumption. In the experiment, dancers trained with the system were able to get real-time feedback about changes in their body temperature, so that they could adjust their movements and training intensity in time. Compared with traditional training methods, dancers using this system have shown significant improvement in the optimization of energy consumption, training efficiency and effect have been improved, not only improve the scientific and accurate training, but also provide real-time feedback for dancers to help them manage their energy consumption more effectively.

Traditional methods of the edgedetection can't completely extract the low frequency image edge. It is easy for them to discard some important information in the high frequency sub-images. If there is much noise in the image, these methods can not entirely eliminate the noise. We will get the poor image edge because of the noise. In order to solve these problems, we respectively analyze the theories of the mathematical morphology algorithm and the directional wavelet transform. We propose an improved edge detection algorithm based on the mathematical morphology algorithm and the directional wavelet transform. We firstly use the binary mathematical morphology to de-noise and detect the edge of the low frequency sub-image in the wavelet domain. Then we de-noise the high frequency sub-image in horizontal, vertical and diagonal directions. We adopt the Canny operator to detect the edge of the high frequency image. The low frequency edge image and the high frequency edge image can be respectively got by the above algorithms. Finally we can get a complete and continuous edge by using some fusion rules. The results show that the improved edge detection algorithm can well suppress the noise interference. It also can get a more continuous and complete edge image comparing to other methods.

A segmentation process is usually required in order to analyze an image. One of the available segmentation approaches is by detecting the edges on the image. Up to now, there are many edge detection algorithms that researchers have proposed. Thus, the purpose of this systematic literature review is to investigate the available quality assessment methods that researchers have utilized to evaluate the performance of the edge detection algorithms. Due to the vast number of available literature in this area, we limit our search to only open-access publications. A systematic search in five publisher websites (i.e., IEEExplore, IET digital library, Wiley, MDPI, and Hindawi) and Scopus database was carried out to gather resources that are related to the edge detection algorithms. Seventy-three publications that are about developing or comparing edge detection algorithms have been chosen. From these publication samples, we have identified 17 quality assessment methods used by researchers. Among the popular quality assessment methods are visual inspection, processing time, confusion-matrix based measures, mean square error (MSE)-based measures, and figure of merit (FOM). This survey also indicates that although most of the researchers only use a small number of test images (i.e., less than 10 test images), there are available datasets with a larger number of images for digital image segmentation that researchers can utilize.

This research detailed a model for detecting fungal diseases via techniques for processing images of cotton leaves. The work allowed to develop a model based on the set of preprocessed data, to formulate the developed model, to simulate and evaluate the model. It is about detecting fungal diseases in cotton cultivation. The image data records were collected in an online data repository consisting of images of cotton leaves infected with fungal diseases and normal leaf images. In addition, other images of infected and uninfected cotton leaves were collected in cotton production fields in the Segbana region in Benin Republic. The model was formulated based on watershed segmentation technique by applying edge detection algorithm and K-Means Clustering;and Support Vector Machine (SVM) for classification. The simulation was done using MATLAB with Image Processing Toolbox 9.4. The results gave an accuracy of 99.05%, specificity 90%, misclassification rate 0.95%, recall rate 99.5% and precision 99.5%. In addition, with less computational effort and in less than a minute, the best results were obtained, showing the efficiency of the image processing technique for the detection and classification of infected and uninfected leaves. It was concluded that this approach was applied to detect fungal diseases on cotton leaves to promote the production and harvest of good quality cotton and valuable cotton products.

Salt rocks exhibit a complex mechanical behaviour by reflecting large deformations at low deviatoric stresses. Since the propagation and creation of cracks due to blasting can disrupt the mine safety and cause irreparable failures in underground spaces, it is important to assess the impacts of blasting on different parts of a salt stope and pillar mine after each blasting round. This study assessed the impacts of blasting operation on discontinuities in a salt stope and pillar mine by using a developed image processing-based methodology. Various photo samples were collected from different parts of the mine pillars and walls. Photographs were taken at four different blasting rounds before and after each round. The Sobel filter for edgedetection was developed in Matlab, and the photographs were processed to assess the impacts of blasting on the discontinuities. The assessment was performed by comparing the processing results before and after each blasting round for the photographs. The effects of distance from blasting points, detonation direction and the amount of charge per each blasting round were considered in the assessment process. The amount of charge per blasting rounds and distance from the blasting points indicated higher effects than detonation directions. The assessment results indicated that the impacts of the blasting operation on the discontinuities decreased and became almost ineffective at distances greater than 30 m. Also, the points located at the end of the mine, as a closed space, experienced the greatest impact of the blasts.

In the context of the rapid development of science and technology and the modernization of the legal system, criminal activities are becoming more and more intelligent and technological, which also puts forward higher requirements for criminal technology. The current criminal technology equipment is relatively backward, and the technical level is not high enough, resulting in a low utilization rate of trace material evidence extraction, which directly affects the role of criminal technology in the investigation and solving of cases. In recent years, fingerprint recognition algorithms and image edge detection algorithms have been widely used in various fields. This work studied the application of fingerprint image fuzzy edge recognition algorithm in criminal technology, in order to improve the level of criminal technology and the utilization rate of physical evidence extraction. The criminal technology system is upgraded and optimized by combining fingerprint recognition algorithm and image edge detection algorithm. And fuzzy theory is added to ensure the feasibility of the research. The experimental results show that the fuzzy edge recognition algorithm of fingerprint image can improve the level of criminal technology and the utilization rate of material evidence to a certain extent. The utilization rate is increased by 7.04%. The recognition accuracy of the fuzzy recognition method is also 13.2% higher than that of the methods in the literature.

This paper designs an intelligent groundwater level monitoring system based on image recognition and Internet of things (IoT). Image recognition technology was employed to process the water level image, and determine the water level line. The IoT was adopted to transmit the collected multimedia data accurately to the monitoring end, thereby realizing the automatic remote monitoring of real-time water level. After analyzing the image recognition technology and the key algorithm of water level recognition, the authors designed the whole process of groundwater level monitoring with two modules: water level monitoring base station, and remote monitoring management center. The water level monitoring base station is embedded with a data acquisition module to periodically collect data, including water level, videos, and images. The collected data were sent to the remote monitoring management center through the cellular network. Then, flood or low water warning could be determined according to the historical data. Finally, the proposed groundwater level monitoring system was tested. The results show that the system not only solves the problem of measurement accuracy, but also improves the work efficiency.

Among metrology tools in the semi-conductor manufacturing, critical dimension scanning electron microscopes (CD-SEM) are the most broadly used, especially due to their high resolution, low destructivity, and high throughput. Contour metrology on CD-SEM images has become essential for characterization, modelling, and control of advanced lithography processes. In particular, OPC model's accuracy can be highly improved using contours metrology. One of the issues when dealing with CD-SEM metrology is that the results are noise sensitive. Moreover, diminishing noise in CD-SEM acquisition leads to resist shrinkage due to exposure time increase. In addition, post-treatment of these shrinkage effects requires compensation algorithms such as artificial intelligence (AI)driven algorithms, that are another contributor to the error budget of metrology systems. There is thus a need for an accurate, robust to noise, and purely deterministic edge detection algorithm. In this article, we evaluate the benefits of relying on a model-based contour extraction approach for performing measurements. This approach is applied onto both synthetic and experimental CD-SEM images with various patterns (mostly 2D) and noise levels to assess the influence of image integration (frame number) on the contour detection and CD measurement. We demonstrate that a model-based contour extraction algorithm is able to precisely characterize SEM-induced 2D resist shrinkage. We observe that this model-based approach is more robust to noise than standard algorithms by 21% on synthetic data and by 36% on experimental data. Another way of seeing it is, while keeping the same precision, a model-based contour extraction approach can significantly reduce the requested image frame number. The benefits of adopting this approach range from reducing the shrinkage effects to improving SEM image acquisition time. Eventually, no step of shrinkage modelling calibration nor AI-driven image post processing are needed which i

Crack detection is a crucial task in periodic pavement survey. This study establishes and compares the performance of two intelligent approaches for automatic recognition of pavement cracks. The first model relies on edgedetection approaches of the Sobel and Canny algorithms. Since the implementation of the two edge detectors require the setting of threshold values, Differential Flower Pollination, as a metaheuristic, is employed to fine-tune the model parameters. The second model is constructed by the implementation of the Convolution Neural Network (CNN) - a deep learning algorithm. CNN has the advantage of performing the feature extraction and the prediction of crack/non-crack condition in an integrated and fully automated manner. Experimental results show that the model based on CNN achieves a good prediction performance of Classification Accuracy Rate (CAR) = 92.08%. This performance is significantly better than the method based on the edge detection algorithms (CAR = 79.99%). Accordingly, the proposed CNN based crack detection model is a promising alternative to support transportation agencies in the task of periodic pavement inspection.
