In order to improve the accuracy of bird sound recognition under non-stationary noise

a rapid bird sound recognition method using anti-noise texture features was proposed.This method also solved the problem of big occupation space

as well as large computation

time-consuming of gray level co-occurrence matrix (GLCM) in extracting texture features.The method contained three steps.Firstly

short-time spectrum estimation was conducted on noise spectrum of bird sound to get the enhanced spectrum.Then

sum and difference histograms (SDH) were applied to calculate texture features rapidly.Finally

random forest (RF) was used to make classification.In the experiment part

two contrast experiments were designed.The results show that this method has good recognition performance

lesser time consumption;meanwhile

it is robust to noise.
