Did you know?
In fractal geometry, the Higuchi dimension (or Higuchi fractal dimension (HFD)) is an approximate value for the box-counting dimension of the graph of a real-valued function or time series. This value is obtained via an algorithmic approximation so one also talks about the Higuchi method. It has many applications in science and engineering and has been applied to subjects like characterizing primary waves in seismograms, clinical neurophysiology and analyzing changes i… WebFeb 13, 2024 · The Higuchi algorithm requires a pre-defined k max value as an input, along with the target time-series.

WebOct 15, 2024 · The Higuchi algorithm requires a pre-defined k m a x value as an input, along with the target time-series. This value is usually determined by sampling the results returned by different values of k m a x and selecting a value based on the range of k m a x where the fractal dimension is stable. WebSep 15, 2024 · Higuchi algorithm [26] is a simple method which calculates fractal dimension of time series directly in the time domain. The basis of the algorithm is a measure of length of the curve that represents the considered time series while using a segment of samples.
WebJan 15, 2024 · The Higuchi method uses the time series and a parameter with the property (here, denotes the ceiling function) to compute a fractal dimension, which we refer to as … WebHiguchi algorithm gave better accuracy as FD values were closer to the theoretical FD ones, and it was finally chosen to compute the FD features. We apply a sliding window and calculate one FD value per sample per channel. Number of channels used in the recognition algorithm defines a size of the feature vector as follows: 12 {, ,, } n FFDFD FD ...
