Because the flaws appear in softgel shells edge is difficult to detect, these two cameras are arranged symmetrically upon softgels with a certain angle to avoid blind area. An image segment method combined automatic threshold and edge detection is proposed to extract the outer contour of softgels. The internal flaws can be detected by dynamic threshold and morphological feature analysis. The experiments shows that the flaws in fish oil softgels such as missing pill, excess pill, abnormal pill, bubbles, black spots and rubber defects can be detected successfully, and the encapsulating line is distinguished from those defects. The resolution of detection is smaller than 0.1mm and the detection accuracy is about 99.9%.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025464","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 WSN monitoring system network, a protocol stack dispatcher, known as Operating System Abstraction Layer (OSAL) over TI's ZStack protocol stack, was chosen to fulfill the strict requirement for the performance of real-time data acquisition and control, as well as the stability of operation system.

However, the host media acts as interference that degrades the watermark robustness, especially in high-payload applications. In this paper, an informed embedding method for CPSK-based watermarking is proposed. The host is utilized at the embedder to improve the decoding performance at the extractor. Theoretically, compared with the non-informed methods such as traditional CPSK and code division multiple access (CDMA), the proposed method can reduce the decoding error rate by several orders of magnitude under the same watermark strength and payload. Moreover, experiments are conducted in audio watermarking, and the informed CPSK method exhibits better robustness against signal processing and attacks.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121631376","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 vehicles can only exchange the control information in control channel interval and the service information in service channel interval separately, but the wireless resource could not be used efficiently. In this paper, we introduce the concept of cluster and propose a new mechanism based on TDMA. In our scheme, vehicles are grouped into clusters and each cluster elects a cluster head as the dedicated central controller of the cluster. The cluster head is responsible to consolidate, forward the message sent by the cluster members and schedule transmission slots for them, thus the cluster members can use the control channel interval for service traffic and efficiently improve the throughput of non-safety message. The simulation results show that the proposed MAC protocol achieves higher packet deliver ratio and throughput for the service data.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122804706","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}

To overcome these problems, a general seal registration and identification approach is proposed in this paper. This method uses the classic scale invariant feature transform (SIFT) algorithm to extract the key points. To register the seal accurately, the Random Sample Consensus (RANSAC) algorithm and the Least Squares Method (LSM) are used to obtain the transformational matrix. Then the invariant features are extracted based on residual image. At last, the Normal Bayesian classifier (NBC), K-Nearest Neighbor classifier (K-NN) and the Support Vector Machine (SVM) are combined to classify the feature vector. The experiments demonstrate the identification ability of the proposed approach.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130688667","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}
