Collusion attack is a cost effective attack against digital fingerprinting where several copies with the same content but different fingerprints are combined to remove the original fingerprints. In this paper, we consider average attack and several nonlinear collusion attacks on independent Gaussian based fingerprints, and study the detection performance of several commonly used detection statistics in the literature under collusion attacks. Observing that these detection statistics are not specifically designed for collusion scenarios and do not take into account the characteristics of the newly generated fingerprints under collusion attacks, we propose pre-processing techniques to improve the detection performance of the detection statistics under collusion attacks.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

Our analysis at all supported bitrates (i.e., 2, 5.5. and 11 Mbps) establishes that the error patterns are not memoryless, and therefore, they exhibit a certain level of temporal dependencies. Thus, we evaluate the suitability of a two-state Markov model to capture the channel behavior. Non-stationarity of the error patterns renders such a simplistic model inadequate, and hence, we consider higher order models. This formulates a key contribution of this paper, and that is, a hierarchical Markov model, which captures the non-stationarity of the channel while employing real-time application-specific considerations to determine state-transition probabilities.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

The key advantage of the Lectern II approach is that all important lecture components can be effectively captured without video. Lectern II employs the touch-sensitive screen technology to build a \"digital desk,\" which is shown to be able to effectively support and transparently capture the standard classroom lecturing activity. Recorded lectures can be edited and automatically uploaded to a Web server, and than viewed by students via a standard streaming player. As the total cost of a complete Lectern II system is under $4,000, Lectern II represents the first course lecture recording system that has the potential to be widely deployed in the classrooms of universities and K-12 schools.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

Limitations of the raw data mapping used in FIowField motivated work on applying interpolation techniques to improve the data representation. Thus far, bicubic interpolation provides the most effective method for initial processing. We observed two factors limiting the quality of the representation: the spacing of the sensors, and the pressure-distributing property of the touchpad surface.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

We present a real-time MPEG video coding system with information look-ahead for constant bit rate (CBR) applications, such as video-on-demand (VoD) over ADSL. This scheme employs two MPEG encoders. Both encoders operate at the same CBR. The second encoder has a buffer to delay the input by an amount of time relative to the first encoder to create a look-ahead window. In encoding, the first encoder collects the information of statistics and rate-quality characteristics. An on-line information processor then uses the collected information to derive the best coding strategy for the second encoder to encode the incoming frames in the look-ahead window. The second encoder uses the encoding parameters from the processor as the coding guide to execute the coding strategy and generate the final bitstream. Results on an IBM MPEG-2 encoder testing system with a 15 frame look-ahead window have shown that the scheme can obtain a 0.6 to 1.6 dB improvement in PSNR over the conventional single encoder on MPEG test video sources. Moreover, measured by the Tektronix Inc.'s picture quality analysis (PQA) system, this scheme achieved 0.87 /spl sim/ 1.35 reduction in PQA measurement. The visual quality improvement is also very evident.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat.

When \"background\" and \"foreground\" both present, the region is considered to have multiple objects, otherwise it corresponds to a single object. We implement the model based on certain image features of the region that effectively tell the difference between \"background\" and \"foreground\".

The method consists of a shape matching step in which the contents of the user sketch are compared with the contents of a shape database and of a placement step in which similar shapes from the database are properly aligned and replace automatically the contents of the user sketch. Shape matching uses a mixture of local and global shape features such as the turning function difference and the degree of openness of a curve.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.
