AUDIO INDEXING AND RETRIEVAL IN MPEG-1 COMPRESSED DOMAIN
This paper proposes a novel audio retrieval method using a two-resolution-level index scheme in MPEG-1 compressed domain. A window-resolution-level index extracted in classification step is used to locate the possible matches. A more accurate searching procedure on group resolution level is performed only if there is a ‘possible’ match between query and database. Experimental results show that the proposed method can achieve a better precision and recall rate than traditional audio retrieval method. And dramatically reduce the computational time.
