noise detection threshold

基本解释

However, the traditional weak signal detection method, input signal to noise ratio threshold are subject to certain restrictions, it is difficult to further reduce.
然而，傳統的微弱信號檢測方法，輸入信噪比門限受到一定限制，很難進一步降低。
To discern edge and noise in multiresolution edge detection used single threshold, we put forward a kind of adaptive threshold and improve the method of edge linking.
