Determining traffic volume automatically and in real-time assists drivers to dynamically plan their trips more efficiently. Our traffic monitoring system uses the virtual line graph to facilitate the detection of vehicles, classification of vehicle types, tracking of individual vehicles, and subsequently an accurate count of the number of vehicles. The virtual line analyzer detects vehicles as they cross a virtual boundary. The goal of this traffic monitoring system is to provide a real-time and accurate vehicle counter while taking advantage of stationary Web-cams, fixed highways and lanes, and deterministic vehicle characteristics.","PeriodicalId":90694,"journal":{"name":"Proceedings.

Due to the fact that TCP employs congestion control and retransmissions and that UDP and TCP packets are treated differently by routers, TCP has much longer delays than those of UDP to deliver an image, but packet losses in UDP may lead to poor decoding quality if the image is single-description coded (SDC) and the losses cannot be concealed. We study the use of UDP to deliver multi-description coded (MDC) reconstruction-based subband-transformed (ST) images and the reconstruction of missing information at a receiver based on information received. To facilitate recovery from UDP packet losses, we propose a joint sender-receiver approach for designing optimized reconstruction-based subband transform (ORB-ST) in MDC. We then carefully evaluate the delay-quality trade-offs between the TCP delivery of SDC images and the UDP and combined TCP/UDP delivery of MDC images. Experimental results show that our proposed ORB-ST performs well in real Internet tests, and UDP and combined TCP/UDP delivery of MDC images provide a range of attractive alternatives to TCP delivery.","PeriodicalId":90694,"journal":{"name":"Proceedings.

The 3D facial caricaturing method uses a 3D (polygon data) face model. An automatic method for extracting regions of the facial parts is technically proposed, and the feature points are extracted from those regions. We propose a wire frame model composed of 44 feature points and 82 polygons to cover a head. To generate a caricature from the polygon data, the individuality feature is defined by the difference of the feature points between the input face and the mean face, which was defined from the average of many input faces. We also propose a method for producing the 3D figure of a human facial caricature.","PeriodicalId":90694,"journal":{"name":"Proceedings.

The method proposed involves a fast, reliable and computationally efficient algorithm, which exploits the colour information in an image to segment the face region. The colour information is derived and used to classify pixels in the image into different levels depending on the value of the colour information for that pixel. Once this is achieved, a priority-labelled fast marching level set algorithm is utilised to locate the face region. The performance of the fast marching face-segmentation algorithm is illustrated by some simulation results carried out on head-and-shoulder test images.","PeriodicalId":90694,"journal":{"name":"Proceedings.

In order to construct the video portal, we deal with structured video with metadata. Our system defines the structure of video in terms of document type definition (DTD), and describes the metadata of video with XML according to the DTD.

In particular, the most characteristic frames/shots (key-frames/shots) are extracted by estimating appropriate points on the feature vector curve, which represent in an optimal way the corresponding trajectory. This is performed by minimizing the approximation error of the feature vector curve and the respective curve formed by the estimated points using an interpolation scheme. A genetic algorithm is used for the minimization task, since the complexity of an exhaustive search is too large to be implemented. Furthermore, a fast technique for increasing the number of extracted key-frames/shots is presented.","PeriodicalId":90694,"journal":{"name":"Proceedings.

A microphone array is an ideal candidate for this purpose. However, this approach requires localizing the target talker. Conventional talker localization methods in multiple sound source environments not only have difficulty localizing the multiple sound sources accurately, but also have difficulty localizing the target talker among known multiple sound source positions. To cope with these problems, we propose a new talker localization method consisting of two algorithms. One algorithm is for multiple sound source localization based on CSP (cross-power spectrum phase) analysis. The other algorithm is for sound source identification among localized multiple sound sources towards talker localization. We particularly focus on the latter statistical sound source identification among localized multiple sound sources with statistical speech and environmental sound models based on GMMs (Gaussian mixture models) and a microphone array towards talker localization. We especially evaluate the performance of the proposed algorithms with the RWCP sound scene database in real acoustic environments (RWCP-DB).","PeriodicalId":90694,"journal":{"name":"Proceedings.

However, correlation-based detection is not actually the best choice, as it does not utilize the distributional characteristics of the image being marked. Accordingly, an efficient watermark detection scheme for DWT coefficients is proposed as optimal for non-additive schemes. Based on the statistical decision theory, the proposed method is derived according to Bayes' decision theory, the Neyman-Pearson criterion, and the distribution of the DWT coefficients, thereby minimizing the missed detection probability subject to a given false alarm probability. The proposed method has been tested in the context of robustness, and the results confirm the superiority of the proposed technique over conventional correlation-based detection methods.","PeriodicalId":90694,"journal":{"name":"Proceedings.
