In this paper, based on digital image processing technology, a series of preprocessing operations such as graying based on color components, filtering denoising, histogram equalization and so on are carried out to enhance the image effect. Then, the suspicious fire area obtained based on color component difference image is processed by threshold segmentation and edge detection. In the processing of flame image, patternrecognition technology is of great significance to the extraction of flame image. Computer vision theory is the key to fire location. With this scheme, the system can effectively eliminate the interference of distance and light intensity in fire detection, and improve the recognition accuracy.
Partition-based feature extraction is widely used in the patternrecognition and computer vision. This method is robust to some changes like occlusion, background, etc. In this paper, partition-based technique is used...

With the improvement of people's living standard, the number of cars on the road has increased dramatically. Vehicle recognition is greatly significant for intelligent traffic management. In this paper, a hybrid model of vehicle recognition algorithm based on VGG16-softmax hybrid model is proposed. The convolutional neural network called VGG16 is used, Imagenet is used for pre-training, migration learning is used to migrate parameters to the new training model, variational auto-encoder is used for data reconstruction, and finally softmax multi-classifier is used for classification. Experiments show that this method can save time, get better vehicle feature of details and higher accuracy.

Quality control chart patternrecognition plays an extremely important role in controlling the products quality. By means of real-time monitoring control, the abnormal status of the product during production can be timely observed. A method of control patternrecognition based on convolution neural network is proposed. Firstly, the control chart patterns (CCPs) are analyzed, the statistical characteristics and shape features of the control charts are considered, and the appropriate characteristics to distinguish the different abnormal patterns are selected;secondly, deep learning convolution neural network is trained and learned;finally, the feasibility and effectiveness of the control chart patternrecognition are verified through Monte Carlo simulation.

The elasticity principles have become one of the most important features of contemporary distributed systems. This novel paradigm has major consequences on Petri nets modeling. The problem is to decide whether an arbitrary Petri net satisfies the elasticity and how to make it elastic. The problem is solved by synthesis of Fractal Petri nets. Fractal Petri nets based on Iterated Algebraic System which makes possible elastic synthesis by incrementing or decrementing of original Petri net. One of the important tasks is recognition of a subnet which used as a pattern for elastic synthesis. For this purpose evolutionary classification of Petri nets based on subnets synthesis is introduced. And furthermore, algebraic operations replication and composition make elastic synthesis object-oriented. Control of the elasticity over the resources and system behavior is achieved with the use of patterns overlapping technique.

Road condition evaluation is a critical part of gravel road maintenance. One of the parameters that are assessed is loose Gravel. An expert does this evaluation by subjectively looking at images taken and written text for deciding on the road condition. This method is labor-intensive and subjected to an error of judgment; therefore, it is not reliable. Road management agencies are looking for more efficient and automated objective measurement methods. In this study, acoustic data of gravel hitting the bottom of the car is used, and the relation between these acoustics and the condition of loose gravel on gravel roads is seen. A novel acoustic classification method based on Ensemble bagged tree (EBT) algorithm is proposed in this study for the classification of loose gravel sounds. The accuracy of the EBT algorithm for Gravel and Nongravel sound classification is found to be 97.5. The detection of the negative classes, i.e., non- gravel detection, is preeminent, which is considerably higher than Boosted Trees, RUSBoosted Tree, Support vector machines (SVM), and decision trees.

Most of the people in the world rely on traditional medicine which is made from medicinal plants. However, very few works concentrate on automatic classification. Therefore, the automatic classification of medicinal plants demands more investigation which is an important issue for conservation, authentication, and production of medicines. In this paper, for automatically classifying medicinal plants, we present a Multi-channel Modified Local Gradient pattern (MCMLGP), a new texture-based feature descriptor that uses different channels of color images for extracting more significant features to improve the performance of classification. We have trained our proposed approach using SVM classifier with various kernels such as linear, polynomial and HI. In addition, we have used different feature descriptors for comparative experimental analysis with MCMLGP by conducting the rigorous experiment on our own medicinal plants dataset. The proposed approach gain higher accuracy (96.11%) than other techniques, and significantly valuable for exploration and evolution of medicinal plants classification.

The sensor information fusion system was composed of complex factors, and there was no unified quantitative standard for each factor. During the system evaluation, the existing evaluation method cannot be applied to all influencing factors, and the result of the evaluation cannot represent the true performance of the system. This paper proposed an evaluation method combining cloud theory and fuzzy patternrecognition model. Based on the cloud theory, the reasonable conversion of qualitative indicators was realized, and the uncertainty of attribute factors was evaluated indefinitely. Combined with the fuzzy patternrecognition model, an evaluation model was established for quantitative indicators, and it was comprehensively processed by fuzzy evaluation method. Evaluation examples show that the method can more accurately and objectively evaluate the performance of the system.
