This paper presents a dynamic trajectory planning algorithm for wheelchairs to pass a door smoothly and automatically. It is a sensor-based approach in which two laser rangefinders are deployed in the wheelchair for real-time door detection. To generate smooth trajectories that enable a wheelchair to pass a door perpendicularly, Bézier curve based trajectories are calculated repeatedly during the whole course of door passing. The proposed approach is tested on a real wheelchair and the experimental results are presented to show the good performance and effectiveness of our proposed automatic door passing strategy.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125574246","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 proposed method decomposes a face image into multiple frequency bands using wavelet transform. Each sub-band in the wavelet domain is divided into non-overlapping blocks. Then, local binary pattern histograms (LBPHs) are extracted from each block in each subband using only 4 neighbours to extract LBP code. Then, all of the LBPHs are concatenated into a single feature histogram to effectively represent the face image. Finally, the extracted face features are embedded in an image using one of the robust steganography techniques in order for them to be ready for transmission. PSNR between original and stego-image is calculated to measure invisibility of the system, while recognition rate of the system is calculated using Euclidean distance followed by a nearest neighbour classifier. The recognition is performed on the receiver side after extracting the embedded face features. The above strategy was tested on two publicly available face databases (Yale and ORL) using different scenarios and different combinations of sub-bands. Results obtained show that embedding LBPH features using our method will give higher invisibility whilst maintaining the recognition rate at the same level or better when compared with the original uniform LBP.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124380629","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 anomaly can be overcome by using a centralized data sink, equipped with more storage and processing capabilities and which can also serve as the decider on the occurrence or otherwise of the event of interest based on selected readings of a subset of the deployed nodes. It is known that selecting a finite subset of a universal set can be intractable especially with relatively large size of the problem space. In this paper, we propose the application of T-norm Fuzzy Logic(TFL) to address the sensor selection problem and compare its performance to that of a standard Genetic Algorithm (GA). Extensive simulation results reveal the usefulness of this approach and how it is closely related to the GA technique.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"21 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132118546","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}

Recent seminal work has proposed that there are theoretically derived upper limits to sampling rate. In this paper we explore the maximum sampling rate to use for estimating packet loss probability given a fixed number of samples, by simulation. Our results show that there is a strong relationship between the sampling rate and the accuracy of measurement. We find the maximum sampling rate for optimal measurement of PLP for specific network scenarios given a fixed number of samples. An important area of application of this work is certain Measurement Based Admission Control scenarios, where faster measurement is important.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123543243","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 is exacerbated in wide angle radar systems where there are likely to be 100 or more responses. Existing methods of interpretation reject low amplitude responses that can be from a close target of low radar cross section. This could result in a critical target not being detected. These are most likely to be responses from a bicycle or a pushchair but could be the only response from an electrical vehicle with a small number of metal components with a small radar cross section at the front of the vehicle. We present a method in which confidence estimates are used to preserve all radar responses and apply constraints to radar responses from a set of radar chirp waveforms, each from a set of radar sensors and reduce the level of ambiguity to a manageable level.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126919373","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 proposed method uses adaptive local thresholding to create an initial binary mask for an image. This is followed by the use of morphological operations to remove background artifacts. Then an adaptive algorithm is proposed to automatically detect and remove the pectoral muscle depending on the gray-level intensity values. Preliminary results of experiments conducted on the Mini-MIAS database (Mammographic Image Analysis Society, London, U.K.) show that the proposed method achieves a near 100% success rate for breast contour extraction and the proposed method for pectoral muscle removal achieves nearly 89% accuracy. More importantly, the proposed pre-processing techniques improved the mammogram classification results when compared to using previous pre-processing methods.","PeriodicalId":309053,"journal":{"name":"2013 5th Computer Science and Electronic Engineering Conference (CEEC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133193138","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}
