Abstract
Certain aspects of the present disclosure relate to methods and systems for noise reduction in analyte data. Raw analyte data is input into a partitioning algorithm to generate partitioned data. An adaptive filter generates rough filtered partitions reducing a noise component in each partition of the partitioned data. A smoothing algorithm smooths the rough filtered partitions to generate smooth filtered data with reduced noise.
Claims20
A method for noise reduction in analyte data, the method comprising:
- receiving, by a processor, raw analyte data corresponding to a noisy signal trace from an analyte sensor;
- partitioning, by the processor, the raw analyte data into a plurality of partitions;
- applying, by the processor, an adaptive filter separately to each partition to generate rough filtered partitions with a reduced noise component in each partition;
- and
- applying, by the processor, a smoothing algorithm across the partitions to smooth the rough filtered partitions from each partition to generate smooth filtered data forming a single smoothed signal trace.
A system for noise reduction in analyte data, the system comprising:
- an analyte sensor system configured to generate raw analyte data for a user;
- a memory comprising executable instructions;
- a processer in data communication with the memory and configured to execute the instructions to:
- receive the raw analyte data corresponding to a noisy signal trace from the analyte sensor system;
- partition the raw analyte data into a plurality of partitions;
- apply an adaptive filter separately to each partition to generate rough filtered partitions with a reduced noise component in each partition;
- apply a smoothing algorithm across the partitions to smooth the rough filtered partitions from each partition to generate smooth filtered data forming a single smoothed signal trace;
- and
- display the smooth filtered data to the user.
A computer-readable medium comprising instructions which, when executed by a processor, cause the processor to perform a method for noise reduction in analyte data, the method comprising:
- receiving raw analyte data corresponding to a noisy signal trace from an analyte sensor;
- partitioning the raw analyte data into a plurality of partitions;
- applying an adaptive filter separately to each partition to generate rough filtered partitions with a reduced noise component in each partition;
- and
- applying a smoothing algorithm across the partitions to smooth the rough filtered partitions from each partition to generate smooth filtered data forming a single smoothed signal trace.
