一种快速鲁棒的广告音频指纹提取方法
Fast and Robust Extraction Method for Advertising Audio Fingerprint
摘要
Abstract
TV commercial detection using audio features has many advantages such as high speed and accuracy. This paper presents a fast and robust audio fingerprint extraction algorithm. The optimized frequency domain is divided into 33 bands, and the energy differences of the neighbor bands in current frame and in the previous frame are extracted separately. And the sum of the energy differences is set as corresponding value of 0 or 1. The audio fingerprint can be generated by 32 values of 0 or 1 in each frame. Experimental results show that the method proposed ensures high extraction speed and robustness against common audio signal operations.关键词
