Diverse explosion effects can be created automatically while still allowing the animator to adjust the processes involved. This paper discusses an explosion animation system, X-Sim, that incorporates physical principles relevant to the generation of an explosion in a compressible medium. used in scientific research, produce physically correct results but demand substantial computational resources and do not provide support for artistic expression. Software tools typically allow artists to re-create the appearance of an explosion but ignore physical processes. Producing real explosions, however, is costly and potentially dangerous and special effects technicians have been turning to software to generate explosion sequences. View full-textĮxplosions are among the most common special effects employed in the entertainment industry. 1 Introduction Most research on audiovisual data segmentation and indexing has primarily focused on visual information, and very little work has been done on the analysis of its audio content, especially that of sound ef. Also, a query-byexample retrieval approach for sound effects is proposed on top of the archiving scheme, which is proved to be highly efficient and effective. An accuracy rate of 86% for sound effects classification is achieved with the proposed method. In addition, it will have applications in surveillance by recognizing sounds related to criminal activities. For example, video scenes of gun fight can be retrieved by searching for sounds of. The proposed approach can be used to retrieve audio/video segments in studios, audiovisual libraries, and family entertainment applications. We present a method for the classification of sound effects which exploits time-frequency analysis of audio signals and uses the hidden Markov model as the classifier.
