A robust pre-processing skin detection algorithm can significantly increase the performance of an application in both terms of speed and accuracy. Skin segmentation is often computationally simple, though in many conditions, uneven and nonlinear illumination degrades its performance. Recently, many methods have been proposed to solve the problem, yet most of them are not applicable in different conditions and disparate illuminations. This paper proposes an algorithm which employs not only a pixel-based processing, but also an additional neighbor-based and region-based processing. This enhances the output of the algorithm. Also a novel method in which the YCbCr image is converted to a ternary image by means of a set of decisive rules is employed. In a further processing stage, a region-based algorithm is used to decide with a high certainly on the pixels which are not skin. Results demonstrate that the proposed algorithm is robust and capable of detecting skin windows comparable with state of the art algorithms.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114639310","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 presented decode-and-forward protocol for wireless relay channel by utilizing repeat-accumulate codes as the coding scheme in the relay. The main advantages of the RAC over another code that makes the RAC is more considered for this research are the complexity of encoding is linear in the code length, have a simpler design, and easier to combine with modulator or detector. Simplicity is the main factor for using RAC in this research because in the multihop wireless communication concept, the information processing that occurs in every node or in every relay should not be complicated. In this paper, RAC is employed in wireless relay channel for the LOS model and urban model. The result shows that in the LOS model, RAC only show BER improvement when the relay position is exactly in the mid between information source (S) and destination (D). In urban channel model, the BER improvement can be observed, whether the relay is positioned ¼, ½ or ¾ between the information source (S) and the destination (D).","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133420184","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}

CFO is able to damage orthogonality among subcarriers and decrease system performance significantly. There are several researches already focused on ICI mitigation, however most of them only employed restricted inputs for CFO in order to generate Inter Carrier Interference (ICI). This research proposes modified dynamic CFO resulted from Doppler shift and oscillator accuracy tolerance. The CFO value takes user's velocity and random user's direction as well as involving oscillator instability. The main purpose of this research is to reduce CFO in dynamic propagation nature in various users' velocities using Extended Kalman Filter (EKF) method. The result showed that those dynamic CFO values can be reduced using EKF method and thereby enhance OFDM system performance, in this case Mobile WiMAX 802.16e. Besides, this proposed system has the adaptability upon different CFO values by adjusting better improvement for higher speed and worse oscillator's quality.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124574513","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 Periductal fibrosis (PDF) ultrasound images can be applied for the CCA surveillance system which increased patient in endemic area of Opisthorchis viverrini (OV). However, the ultrasound images are lack of contrast and a lot of speckle noise. This paper presented the enhanced algorithm of PDF ultrasound images (EPDF) for the CCA surveillance system in which consist of the Histogram equalization (HE), Speckle reduction method, and Anisotropic diffusion. Firstly, the HE method performed to improve the lack of contrast of the PDF ultrasound images. Then, the speckle reduction method performed to reduce the speckle noise and preserving the edge in the PDF ultrasound images. Finally, the Anisotropic diffusion performed to smooth region in the PDF ultrasound images. The data set in the experimental studies consist of 30 pictures. The performance of the EPDF algorithm from the experimental results gave the best for the CCA surveillance. A successful percentage of the EPDF system achieved at 80.36%. Thus, the EPDF system has the potential to increase the performance for enhancing the PDF in ultrasound images for CCA surveillance system.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127654786","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}
