Underwater imaging is one of the most intuitive means to reflect the internal conditions of the ocean. However, due to the complex imaging environment of the ocean and light scattering in the sea, underwater images exhibit severe degradation, making it difficult to distinguish effective information. Thus, underwater imaging must be enhanced. Compared with traditional methods (e.g. histogram equalization method) and modeling methods, deep learning has been well applied in the field of computer vision. The key points are the acquisition of the training set and the generalization ability of the convolution model. Because the model-based method often needs to measure prior data manually in advance, it will cause inevitable errors; and direct generalization of the neural network will also cause image blurring. In this paper, we design a double U-Net for underwater image enhancement with strong generalization ability, in combination with modeling and deep learning methods. The gray image of the input image is processed with the attention mechanism in advance, and the relevant transmittance information is obtained using a U-Net. Then, the input image is processed with the information output from each layer of the previous U-Net. The final result is obtained by dividing the two U-Net results by pixels. The proposed network is trained using a paired training set generated by CycleGAN. Through quantitative and qualitative analysis, our method is proved to be more effective than the methods in recent papers in the field of underwater image enhancement.","PeriodicalId":210502,"journal":{"name":"2020 8th International Conference on Digital Home (ICDH)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126622420","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}

Those data are stored in large volumes, various types, separate features, and lacking unified data specifications, making it harder to organize and learn. In view of the above challenges, inspired by the knowledge graph models which hold strong power for knowledge representing and reasoning, this paper constructs a knowledge graph model for power grid dispatching regulations with graph convolutional network (KGPGD). Specifically, in the context of the massive growth of grid dispatching data, knowledge extraction methods are used to obtain the entity words and relation words in the specification from the smart grid dispatching control system. The dataset of technical specifications of the smart grid dispatching control system is the real-world provided by the Northeast Branch of State Grid Corporation of China. And then a domain knowledge graph is automatically constructed to study domain-oriented big data of PGD. At the same time, the graph convolutional neural network model is utilized to learn the power grid dispatching knowledge graph features. KGPGD provides a reference basis and decision support for the formulation of the technical specifications of the power grid dispatching system of digital homes.","PeriodicalId":210502,"journal":{"name":"2020 8th International Conference on Digital Home (ICDH)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733975","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}

It is an ill-conditioned task and remains a challenging problem in computer vision. One main challenge in example-based image colorization is how to find the correct correspondence between the grayscale image and the reference color image. In this paper, we propose a novel automatic example-based image colorization method via weighted sparse matching. First, we segment the images into superpixels, and operates at the superpixel level rather than pixels. Then we extract intensity features and texture features for each superpixel, which are then concatenated to form its descriptor. The feature descriptors collected from the reference image composes the representation dictionary. Finally, the correspondence between target grayscale image and the colorful reference image is built by solving a weighted sparse representation learning problem, and the target superpixels are colorized based on the chrominance information from the corresponding reference superpixels. Experimental results demonstrate that our colorization method outperforms several state-of-the-art methods.","PeriodicalId":210502,"journal":{"name":"2020 8th International Conference on Digital Home (ICDH)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130231698","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}

This paper proposes a densely connected feature pyramid segmentation network and applies it to the segmentation of images in real driving scenarios. The feature pyramid network is a kind of feature extractor, which is originally used for object detection. This paper applies it to image segmentation tasks. The densely connected network is used as a part of feature pyramid network to extract features from bottom to top. Through the lateral connection, the features of the bottom-up part and the top-down part are merged. In the final merge stage, the extracted features are transformed to the same size through upsampling and then concatenated together, and finally the segmentation map is output. The experiment is conducted on the CamVid dataset, which is a dataset in actual driving scenarios. In the experiment, the generalization ability of the segmentation model is improved through data enhancement. Based on the densely connected feature pyramid segmentation network, the F1-score on the test set is 0.8895, and the IoU-score is 0.8209.","PeriodicalId":210502,"journal":{"name":"2020 8th International Conference on Digital Home (ICDH)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130991112","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}

The scheme based on k-anonymity model has been widely used. However, the traditional methods have some limitations due to their long convergence time and subjective factors. In this paper, we propose a scheme based on sparse representation, which has high computational efficiency and simple solution. Firstly, we process the data set with certain techniques. Then we introduce the expression of sparse representation between trajectories and add regularization for continuous training.

This domain entity has more complicated structure than the common named entity, and its entity category is more abundant. However, the general method can not solve the problem of domain specific identification. In this paper, we combine self-attention mechanism and iteration dilated convolution neural network (IDCNN) for CNER in judicial domain. The bidirectional gate recurrent unit (BiGRU) model is used to automatically learn the context semantic information of the text and solve the long-distance dependence of the sequence. The model introduce the IDCNN to extract the key features of context semantic information, and capture finer-grained semantic information in underlying texts. The self-attention mechanism is used to analyze the relationship between characters, and the problem of long sequence semantic dilution is effectively solved by means of dynamic weight, and the optimal tag sequence is calculated by integrating conditional random fields (CRF), which further improves the recognition ability of the model. Finally, by analyzing the characteristics of legal documents, the new data set is annotated and the fine-grained named entity recognition is realized. The experimental results on our corpus show that the proposed method can effectively identify the entities in legal documents, and improve performance in the judicial field.","PeriodicalId":210502,"journal":{"name":"2020 8th International Conference on Digital Home (ICDH)","volume":"601 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116306339","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}
