The taste of the brewed coffee is closely related to the quality of coffee beans, which has led to many researchers developing automated methods to accurately distinguish good coffee beans from bad ones. The research often used supervised learning technology by utilizing large sets of labeled data for training, but the labeling requires a substantial amount of manpower that is impractical for real production line usage. To solve this problem, we proposed a method that the combines semi-supervised learning and attention mechanism to classify the two types of coffee beans. Through explainable consistency training and directional attention algorithm, we solve the high-cost problem of labeling data and strengthen the prediction ability of the model. The experimental results show that the study has high classification performance and can achieve an F1-score of 97.21%.","PeriodicalId":164671,"journal":{"name":"2022 IEEE International Conference on Consumer Electronics - Taiwan","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132980223","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}

Airlight estimation plays an important role in image dehazing algorithm. Dark Channel Prior (DCP) is an efficient algorithm to predict airlight. However, the sorting process of DCP causes tremendous computation requirement, limiting its potential in image dehazing chip design. To overcome this limitation, Down-sampling DCP (DS-DCP) is proposed to provide a low complexity algorithm for airlight estimation. Experiment results demonstrate that the computation saving ratio (CSR) of DS-DCP is as high as 98%, while keeping error as minor as 0.22%.","PeriodicalId":164671,"journal":{"name":"2022 IEEE International Conference on Consumer Electronics - Taiwan","volume":"236 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113982662","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}

In the Matlab simulation, our method is completely verified with 6 representative data sets.

And, directed graph Fourier transform is defined by the eigen-decomposition of DLM. Next, the HKS filter is employed to reduce the noise superimposed on the temperature data. Using the Taylor series expansion, the HKS filter can be approximated by a polynomial digraph filter to get a distributed implementation in vertex domain.

To achieve real-time and high-quality video stabilization for fast and large-shaking frames, the main strategy of the proposed method is to find the optimal feature-point match to generate the better transformation matrix. Besides, the image pre-processing is exploited to down-sample the picture and then set the ROI area for substantially increasing the speed of the subsequent processing without affecting the detection of feature points. The proposed method is more cost-effective in stabilization than other approaches, especially for fast and large-shaking frames (e.g., video-shooting while running) and can be applied to the wearable cameras, sports cameras, and vehicle cameras.","PeriodicalId":164671,"journal":{"name":"2022 IEEE International Conference on Consumer Electronics - Taiwan","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116653980","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}

Therefore, this study focuses on PCBA for scratch detection and trains multiple models based on semantic segmentation UNET network architecture. The proposed D-LinkNet is optimized to reduce the problem of missed detection and misclassification caused by complex backgrounds and long span of defects. By comparing various attention modules in different positions and types to improve the accuracy, and using the dilated convolution instead of pooling layer, the encoder-decoder structure is optimized to reduce the loss of information in the downsampling process, simultaneously improve attention module effect. In addition, this experiment uses a small amount of data to increase the amount of data by cutting and augmenting the data, and compares the effect of image cutting size on the accuracy rate to find the best data size for training, and uses IoU as the model scoring method to apply the model with the best segmentation effect to more scratch detection tasks and reduce the labor cost at the factory.","PeriodicalId":164671,"journal":{"name":"2022 IEEE International Conference on Consumer Electronics - Taiwan","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117334790","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}
