We found that SQL-enabled databases provide a flexible and scalable solution to this problem. The examples of actual SQL queries for sport analysis are presented in the paper along with short tutorial on particular aspects of SQL language, which were exploited in our solution.","PeriodicalId":238993,"journal":{"name":"ISPA 2005.

The system applies in the night domain the SVM technique, which has already been successfully implemented in day-light applications, in this project we have developed optimizations in order to meet accuracy and time performance requirement for in-vehicle deployments. In particular, we present a novel pre-SVM processing technique, which performs pixel-level and multi-resolution analysis in order to discard portions of the frame that are not likely to contain pedestrians. This procedure allows exploiting the SVM as a very accurate classifier focused on the most critical cases.","PeriodicalId":238993,"journal":{"name":"ISPA 2005.

The resulting difference image is usually thresholded to obtain objects based on pixel connectedness and resulting blob objects are subsequently tracked. This paper proposes a detection approach not requiring the binarization of the difference image. Local density maxima in the difference image - usually representing moving objects - are outlined by a fast non-parametric mean shift clustering procedure. Object tracking is carried out by updating and propagating cluster parameters over time using the mode seeking property of the mean shift procedure. For occluding targets, a fast procedure determining the object configuration maximizing image likelihood is presented. Detection and tracking results are demonstrated for a crowded scene and evaluation of the proposed tracking framework is presented.","PeriodicalId":238993,"journal":{"name":"ISPA 2005.

We present a novel FMC method relying on the combination of the radial basis functions (RBF) based scattered data interpolation with the encoding capabilities of the MPEG-4 facial and body animation (FBA) international standard. Starting from a manually picked set of correspondences, we find a scattered data interpolation function that precisely fit the source face mesh into the target one. Then, all the MPEG-4 FBA basic movements (encoded as morph targets) of the source face are deformed using the same function and the deformations are mapped to the corresponding vertices of the target mesh. By doing this, we obtain, in a straightforward and simple way, the animatable MPEG-4 compliant version of the target face in a short amount of time.","PeriodicalId":238993,"journal":{"name":"ISPA 2005.

This paper shows that by designing FRM filters building the FB in such a way that the periodic filters are evaluated at the input sampling rate and the masking filters at the output sampling rate, the design as well as the implementation complexity can be further reduced when compared with the designs obtained by using other existing techniques. This is illustrated by means of an example.","PeriodicalId":238993,"journal":{"name":"ISPA 2005.
