- Firstly,the original heart sounds signal was preprocessed by Huang Transform. 首先利用黃變換對心音信號進(jìn)行預處理;
- So, this paper uses mathematical morphology theory to catch heart sound envelope, and then composes the reference noise which is heavily correlative to the noise in the primary PCG signal. 在這里本文又引入了數學(xué)形態(tài)學(xué)理論,利用它提取了心音信號的包絡(luò ),然后合成了自適應濾波需要的參考。 這樣得到的噪聲信號雖然在心音成份部分不能保證與原心音中的噪聲相關(guān),但在心音間隙期二者是強相關(guān)的,利用這種相關(guān)性,在這里濾去間隙期的噪聲信號,得到了分界更清晰的心音圖,為心音成份的識別打下基礎。
