Webnumpy.clip(a, a_min, a_max, out=None, **kwargs) [source] # Clip (limit) the values in an array. Given an interval, values outside the interval are clipped to the interval edges. For example, if an interval of [0, 1] is specified, values smaller than 0 become 0, and values larger than 1 become 1. WebThresholding ¶ pywt.threshold(data, value, mode='soft', substitute=0) ¶ Thresholds the input data depending on the mode argument. In soft thresholding [1], data values with absolute value less than param are replaced with substitute. Data values with absolute value greater or equal to the thresholding value are shrunk toward zero by value.
