ABNORMAL SOUND DETECTION AND IDENTIFICATION SYSTEM IN CAMERA ENVIRONMENT

摘要

PURPOSE: An abnormal sound detection and identification system in a camera environment is provided to efficiently identify audio data as a normal sound or an abnormal sound by using a single class SVDD and SRC and to classify audio data identified as the abnormal sound. CONSTITUTION: An SVDD(Support Vector Data Description) learning unit(142) generates learning data for a single class SVDD. An SRC(Sparse Representation Classifier) learning unit(144) generates learning data for an SRC. An audio data identifying unit(150) identifies audio data as a normal sound or an abnormal sound based on the learning data for the single class SVDD. An audio data classifying unit(160) classifies the audio data according to the type of the audio data which is identified as the abnormal sound.
