The detection performance of 3 cooperation dispositions was evaluated with the criterion of coverage area ratio and mean track initiation distance.

The approach starts by segmenting the word images into their constituent letter representatives through exploiting a set of structural features. For classification, Gabor transform-based features are extracted from each letter that passed to a SVM classifier for recognition. For training and testing, we used IESK-arDB database, which is an Arabic off-line handwritten database, that containing the most common Arabic words as well as security-related Arabic terms. The database is developed in the Institute for Electronics, Signal Processing and Communication (IESK) at Otto-von- Guericke University Magdeburg, Germany. And it is freely available at (http://www.iesk-ardb.ovgu.de/). The approach achieved an average of 70% segmentation accuracy on 600 word images.

We focus on resolving three problems which are fast hand motion capture, hand over face and hand occlusions. At first, an effective dynamic model for state prediction is used. This dynamic model can correctly predict the location of hand which has a rapid movement and quick shape deformation. Then, new energy terms are augmented into the energy function in graph cuts. The additional terms are inspired by multi cues, such as color, motion and spatial-temporal information. Finally, we construct the graph and achieve the hand segmentation in successive frames using min-cut/max-flow algorithm. We evaluate our algorithm in a real American Sign Language video from Purdue ASL Database. Besides, our method can be easily extended to track objects with similar color.","PeriodicalId":143331,"journal":{"name":"2012 IEEE 11th International Conference on Signal Processing","volume":"11 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127778451","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}

Long Term Evolution (LTE), which is the standard of next generation mobile communication systems proposed by The 3rd Generation Partnership Project (3GPP), has implemented some novel and advanced technologies to supply high data rate, high spectral efficiency, low latency, and so on. Although LTE keeps high spectral efficiency, it suffers serious inter-cell interference, which will affect the system performance especially the cell-edge performance. As an effective frequency planning strategy, Soft Frequency Reuse (SFR) is proposed in LTE systems for inter-cell interference coordination as well as maintaining spectrum efficiency. In this paper, we analysis the theoretical inter-cell interference about SFR briefly, and then investigate the system performance of SFR for LTE on railway scenario by varying power ratio, carrier frequency, Component Carrier load balance. With the simulation results, the advantages and limitations of SFR are comprehensively analyzed and compared against the traditional frequency reuse (TFR) as a reference. We give some meaningful conclusions on the performance of SFR scheme, especially the performance improvement when varying the carrier frequency offers the opportunity to implement Carrier Aggregation in LTE. The future work will focus on evaluating the performance of SFR when adopting Carrier Aggregation in the system simulator.","PeriodicalId":143331,"journal":{"name":"2012 IEEE 11th International Conference on Signal Processing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115566779","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}
