As motorcycles are becoming popular for local transportation and environmental friendliness, the demands for license plate recognition have been increasing in recent years. The primary difference between the license plate recognition in automobiles and motorcycles is on the detection of license plates, which is the topic of this study. For automobiles, the license plates are mostly installed on the front or on the back of the vehicle with relatively less complicated backgrounds; however, for motorcycles, the backgrounds can be far more complicated. To better handle complicated backgrounds, we study the case with motorcycle detection as preprocessing so that the search area for the license plate can be better constrained, and compare its performance with the case without the preprocessing. A few detection methods are configured and studied for both the motorcycle detection and license plate detection, including the state-of-the-art part-based model. Considering processing speed and accuracy, the histogram of oriented gradients (HOG) with support vector machines (SVMs) is found to be the best detector for motorcycle license plates.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128537478","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 based on the TETRA and TETRAPOL communication networks, that are currently used by public and private bodies as network infrastructures and are particularly exploited in case of emergency. The proposed system allows the use of both, TETRA and TETRAPOL, low level communications layers. Furthermore, the proposed terminal introduces high level capabilities that enhance the basic functionalities of these communication systems, while preserving the intrinsics security of the standards. The implementation of the proposed terminal architecture is the basis for the development of an integrated European network where emergency services and first responders share communications, processes, and a legal framework, to be used in case of natural disasters and security threats. In this contribution, the terminal architecture and the security analysis are introduced and discussed.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129959535","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}

Developing a mobile application which enables the user to effectively search restaurants from data in these blogs becomes an emerging need. Besides reading the comments, most people will give a glance at food photos of a restaurant and then decide whether to go or what to eat. Therefore, we propose a system to analyze and select representative photos for each restaurant based on blog-platform media. A strong food detection model is trained to retrieve food photos and an aesthetic quality assessment method is utilized to select representative photos. Based on these representative photos, users can more easily have the impression of the restaurant and review the blog in an organized way. The experimental results show that our system can generate better representative photos (i.e. much closer to the users' preferences) than existing blog platforms.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116548761","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 system includes: (i) Personalized facial points tracking algorithm to suit mobile captured data; (ii) Temporal filter that pre-selects probable emotional frames from the input sequence for further processing, in-order to reduce the processing load; (iii) Face registration and operating region selection for compact facial action unit (AU) representation; (iv) Discriminative feature description of AUs that is robust to illumination changes and face angles; and (v) AU classification and intelligent mapping of the predicted AUs to target emotions.

By using the curve-fitting method, we obtain S-P (Size-Playback time) models for all the video segments. On the basis of the S-P models, we propose a novel resource allocation scheme to improve the playback continuity for the clients. First the transmission capacity requirements of all the clients are calculated. Then a new mathematical model is formulated to maximize the total playback time that the packets to be scheduled can support, subject to the transmission capacity requirements of the clients and the network resource constraints. To solve the problem, a resource allocation scheme with low complexity is proposed. Simulation results show that our proposed algorithm can efficiently improve the playback continuity compared with other existing algorithms.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130527741","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}

A novel spatiotemporal saliency detection model is proposed in this paper. The discrete cosine transform coefficients are used as features to generate the spatial saliency maps firstly. Then, a hierarchical structure is utilized to filter motion vectors that might belong to the background. The extracted motion vectors can be used to obtain the rough temporal saliency map. In addition, there are still some outliers in the temporal saliency map and we use the macro-block information to revise it. Finally, an adaptive fusion method is used to merge the spatial and temporal saliency maps of each frame into its spatiotemporal saliency map. The proposed spatiotemporal saliency detection model has been extensively tested on several video sequences, and show to outperform (more than 0.127 in AUC and 0.182 in F-measure on average) various state-of-the-art models.","PeriodicalId":388471,"journal":{"name":"2015 IEEE International Conference on Multimedia & Expo Workshops (ICMEW)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114315782","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}
