Abstract
The present invention relates to a computer-based method for reducing or eliminating baseline drift from a biological (bio) signal. The method includes the steps of dividing the bio signal into a plurality of shorter signals having fixed time intervals, fitting a baseline function to a baseline of each of the shorter signals, and subtracting each baseline function from a corresponding shorter signal, resulting in a bio signal with a flat baseline.
Claims30
A computer-based method for reducing baseline drift in a biological (bio) signal, the method comprising:
- dividing the bio signal into a plurality of shorter signals having fixed time intervals;
- fitting a baseline function to a baseline of each of the shorter signals;
- and
- subtracting each baseline function from a corresponding shorter signal, thereby flattening the baseline of the bio signal.
A device for reducing baseline drift in a biological (bio) signal, the device being constructed and arranged to:
- divide the bio signal into a plurality of shorter signals having fixed time intervals;
- fit a baseline function to a baseline of each of the shorter signals;
- and
- subtract each baseline function from a corresponding shorter signal, thereby flattening the baseline of the bio signal.
A computer-readable storage medium having stored thereon a series of instructions executable by a processor for removing noise from a digital signal, the instructions configured to cause the processor to perform the steps of:
- dividing the bio signal into a plurality of shorter signals having fixed time intervals;
- fitting a baseline function to a baseline of each of the shorter signals;
- and
- subtracting each baseline function from a corresponding shorter signal, thereby flattening the baseline of the bio signal.
