It has larger complexity in order to satisfy the demand of high quality video at low bit rate. Moreover, it requires the effective implementation of all its internal blocks. In the paper, we focuses on the implementation of two important blocks for H.264 encoder. We propose low complexity design of quantization and Context Adaptive Variable Length Coding (CAVLC). The quantization process is responsible for scaling down the value of transform coefficients. CAVLC is useful for a bit stream generation and it is adopted from the concept of modified Variable Length Coding (VLC) technique. The efficient architectures are designed for quantization and CAVLC blocks to have parallel and pipeline data processing. They are implemented on Virtex 4 XC4VLX40 FPGA family using VHDL. The synthesized results are obtained with Xilinx ISE 14.2 and resource, device utilization and timing analysis are reported. The results are compared with related work that shows the better real time performance of both blocks.","PeriodicalId":187874,"journal":{"name":"2014 IEEE International Conference on Computational Intelligence and Computing Research","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115052972","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 approach aims at the reuse of components represented by means of Unified Modeling Language (Uml) diagrams. Designs based on compositions of components have to formally be proved for correctness. In this paper we propose a verification approach by combining trace equivalence and model checking to verify UML-based designs of communication protocols. Our method consists of two steps. Foremost, the internal and external component behaviors are verified independently regarding their formal correctness. Thereafter the correctness and consistency of compositions is verified. This is achieved by generating the component adaptation path as traces during the composition. The requirements, i.e., safety and liveness properties, are formulated using linear temporal logic formulae. We apply the Spin tool as our model checking mechanism. For this, we present a method for automatically transforming the designs into Promela. We evaluate our approach for an example data transfer protocol as a case study.","PeriodicalId":187874,"journal":{"name":"2014 IEEE International Conference on Computational Intelligence and Computing Research","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286088","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}

It is empirically observed that no single algorithm is efficient in extracting all different types of images like building images, flower images, car images and so on. Hence a thorough analysis of certain color, texture and shape extraction techniques are carried out to identify an efficient CBIR technique which suits for a particular type of images. The Extraction of an image includes feature description, index generation and feature detection. The low-level feature extraction techniques are proposed in this paper are tested on Corel database, which contains 1000 images. The feature vectors of the query image (QI) are compared with feature vectors of the database images to obtain matching images(MI). This paper proposes Fuzzy Color and Texture Histogram (FCTH) techniques which extract the matching image based on the similarity of color and edge of an image in the database. The Image Retrieval Precision value (IRP) of the proposed techniques are calculated and compared with that of the existing techniques. The algorithms used in this paper are Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Fuzzy Linking algorithm. The proposed technique results in the improvement of the average precision value. Also FCTH is effective and efficient for image indexing and image retrieval.","PeriodicalId":187874,"journal":{"name":"2014 IEEE International Conference on Computational Intelligence and Computing Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127890119","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 protocol has been designed keeping in view the impact of both small scale and large scale fading environments. Whenever the transmission process encounters a small scale fading environments such as rayleigh or ricean, the action is taken to retransmit the RTS control signal expecting the improvement of the communication environment. In case of large scale fading, the transmission power is increased under the assumption that the communicating environment will remain approximately same in the near future. By using ns2 simulator, performance of FAMAC the proposed MAC protocol is compared with the two other most widely used MAC protocol DCF & EDCF. Avg. end-to-end delay and throughput are taken as the performance measure for the purpose. It was observed that the proposed FAMAC protocol shows improved results in comparison to DCF & EDCF. FAMAC shows higher throughput and lesser avg. delay in comparison to other MAC protocols. It was also observed that in FAMAC, the throughput and avg. and-to-end delay remains unaffected by various fading environment. But in DCF and EDCF, those are affected by Rayleigh and Ricean fading environment.","PeriodicalId":187874,"journal":{"name":"2014 IEEE International Conference on Computational Intelligence and Computing Research","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128753982","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}
