This paper presents a method to classify audio-video data into one of seven classes: advertisement, cartoon, news, movie, and songs. Automatic audio-video classification is very useful to audio-video indexing, content based audio-video retrieval. Mel frequency cepstral coefficients are used to characterize the audio data. The color histogram features extracted from the images in the video clips...

This paper examines the accuracy of audio-video based localization using multiple cameras and multi-microphones. Covariance mapping theory is used to determine the accuracy of audio and video based localization. Both modalities are compared in terms of their ability to provide accurate location estimates of a moving audio-visual source. Relatively, video is found to be significantly more accura...

Present day personal and home hi-fi products are designed to work independently. In the near future these devices will have increased networking capabilities. This connectivity will enable a large number of audio/video (A/V) sources such as CD’s, DVD’s, digital libraries and internet broadcasts to be linked with A/V sinks such as active loudspeakers, recorders and home internet gateways. This p...

Multimedia signal processing, or media processing [1], is the processing of digital multimedia information in a programmable processor. Digital multimedia information includes visual information like images, video, graphics and animation, audio information like voice and music, and textual information like keyboard text and handwriting. With general-purpose computers processing more multimedia ...
