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.
