如何用matlab fastpeakfind检测灰色背景上的峰值? 我正在测试Fileexchange项目的有效性FindPeaksFast使用不同的线宽和背景。测试1成功,该工具检测到1px到10 px的所有峰。然而,测试2在测试时发现在对象绘图的框架上找到峰值的峰值,即灰色背景上的对象(绘图)。该工具在白色背景良好运行。代码...
Thresholding the peaks to locate the Q waves results in detection of unwanted peaks as the Q waves are buried in noise. We filter the signal first and then find the peaks. Savitzky-Golay filtering is used to remove noise in the signal. Get smoothECG = sgolayfilt(ECG_data,7,21); ...
在数字信号处理中,经常涉及到波峰(或波谷)查找算法,比如心率测量、步数计数等。对于周期信号或者准周期信号,有一种称之为Automatic multiscale-based peak detection(AMPD),即自动多尺度峰值查找算法,非常好用。已经用在了本人参与的多个项目中。 其优势是: ...
