The color feature is extracted by quantifying the YUV color space and the color attributes like the mean value, the standard deviation, and the image bitmap of YUV color space is represented. The texture features are obtained by the entropy based on the gray level cooccurrence matrix and the edge histogram descriptor of an image. The shape feature descriptor is derived from Fourier descriptors (FDs) and the FDs derived from different signatures. When computing the similarity between the query image and target image in the database, normalization information distance is also used for adjusting distance values into the same level. And then the linear combination has used to combine the normalized distance of the color, shape and texture features to obtain the similarity as the indexing of image. Furthermore, an experimental results indicated, a weight variation to achieve higher retrieval efficiency and the proposed technique indeed outperforms other schemes in terms of the accuracy and efficiency.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"587 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115978879","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}

Particularly, tattoos are raising obvious evident attention because of their visual and demographic traits as well as their increasing prevalence. However, tattoos on human skin are complicated and large invariance in both structure and skin surface. In order to improve tattoo image retrieval and matching, this paper proposes an approach of tattoo skin detection and segmentation using the image negative method in the pre-processing part. The process is composed of three steps. The first one is the skin detection where we use a variety of skin patches to do the task of human skin colour segmentation using the HSV model, especially, Asian skin colour. Then, in the second step, the image negative method is used for detecting the clear graphic image of the tattoo segment. Finally, we extract the tattoo segment from the skin area of the negative image and, as a result, the tattoo negative image is obtained and can be used for retrieval. Our experimentation has been carried out based on the dataset of tattoo images, gathered from Thai Criminal Records Division - Royal Thai Police, Kingdom of Thailand. Based on the concept of CBIR (Content-Based Image Retrieval), SIFT (Scale Invariance Feature Transform) has been employed in the process of image matching and retrieval. The result has illustrated that the tattoo skin detection and segmentation are efficient and effective for tattoo image retrieval, and, also, reduce the possibility of illogical matches.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133933240","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}

With this dynamic topology, ad hoc network presents many specific problems which had influence on solution that assure QoS such as multimedia applications. However, the rapid growth in number and diversity of real-time network applications has made it imperative to consider the impact of end-to-end delay requirements of traffic on network. The main problems are: node mobility and link failure. Hence, there is a need for efficient routing protocols to allow the nodes to communicate with some QoS guarantee. In this work, the AutoRegressive Moving Average (ARMA) model is used to forecasting resources to meet the QoS requirements in ad hoc networks. We apply this model in Ad hoc On demand Multipath Distance Vector (AOMDV) protocol. The results obtained show that the combination of the AOMDV protocol with the time QoS forecasting mechanisms for real-time service support based on ARMA processes performs better than based on AR processes and the conventional AOMDV.","PeriodicalId":356009,"journal":{"name":"2013 13th International Symposium on Communications and Information Technologies (ISCIT)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131319600","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}
