Recurrent All-Pairs Field Transforms (RAFT) is one of the most powerful deep network based optical flow algorithms, but it is difficult to process in real time on the resource-limited embedded platform. In this paper, we propose RAFT-Lite by compressing the original RAFT model, which is more lightweight and suitable for hardware deployment. We further propose a hardware accelerating architecture on FPGA for RAFT-Lite, which provides an efficient scheduling strategy for the convolution in RAFT to achieve efficient pipeline and resource reuse. On Xilinx ZCU102 evaluation board, the accelerated hardware system can reach 10.4fps processing images with a resolution of 512*396, which is 6.8x of i7-10700@2.90GHz and 46x of ARM Cortex-A53@1.50GHz. Besides, the power consumption is 13.103W.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122523566","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}

A particular challenge is that the collecting and labeling of anomaly examples are usually infeasible before implementation. To tackle the problem, a novel two-stage framework is proposed in this paper to build anomaly estimators with normal data only. Specifically, unsupervised deep representations are learned first by a modified SimSiam where an adaptation for one-class learning is implemented. Then the non-parametric method is adopted to model the distribution of training data on the learned representations as the one-class classifier to detect anomaly. Moreover, we model the distribution with different hierarchy level’s features of the convolutional neural network to achieve both image-level and pixel-level detections. Experiments are conducted on MVTec anomaly detection dataset. Competitive results of 92.6% AUROC score for image-level detection and 95.4% for pixel-level detection are obtained to demonstrate the effectiveness of the proposed method.","PeriodicalId":287137,"journal":{"name":"2022 China Automation Congress (CAC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117076261","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}
