چکیده
ABSTRACT Automatic detection of commercials in digital multimedia material is a challenging task with many applications. This paper presents a novel approach to fast commercial detection based on audio retrieval. It is based on the idea of segmenting energy envelope of audio into units, using only audio signal for matching on a commercial database. Fast searching and matching can be performed with high accuracy, by stepping from unit to unit instead of windowshifting searching and by novel similarity function based on units. Experimental results show that 96.8% recall rate and 98.7% precision rate can be achieved under 0.125 real-time. Index Index

A Histogram Algorithm for Fast Audio Retrieval
This paper describes a fast audio detection method for specific audio retrieval in the AV stream. The method is a histogram matching algorithm based on structural and perceptual features. This algorithm extracts audio features based on human perception on the sound scene and locates the special audio clip by fast histogram matching. Experimental results based on the advertisement detection in T...
متن کاملIntelligent Content-Based Audio Classification and Retrieval for Web Applications
Content-based technology has emerged from the development of multimedia signal processing and wide spread of web application. In this chapter, we discuss the issues involved in the content-based audio classification and retrieval, including spoken document retrieval and music information retrieval. Further, along this direction, we conclude that the emerging audio ontology can be applied in fas...
متن کاملSemantic Similarity for Music Retrieval
We present a query-by-example system for content-based music information retrieval by ranking items in a database based on semantic similarity, rather than acoustic similarity, to a query example. The retrieval system is based on semantic concept models that are learned from the CAL500 data set containing both audio examples and their text captions. Using the concept models, the audio tracks ar...
متن کاملAN ENHANCED CONTENT-BASED VIDEO RETRIEVAL SYSTEM BASED ON QUERY CLIP T.N.SHANMUGAM and PRIYA RAJENDRAN
Content-based search and retrieval of video data has become a challenging and important issue. Video contains several types of audio and visual information which are difficult to extract, combine or trade-off in common video information retrieval. This research work is the enhanced version of our previous research with texture feature extraction. In this paper, we address the specific aspect of...
