This study investigates combining Discrete Cosine Transform (DCT) and Wavelet Transform (WT) for electrocardiogram (ECG) data compression. Combined techniques improve visualization quality with fewer transform coefficients.

Area of Science:

  • Biomedical Engineering
  • Signal Processing
  • Data Compression

Background:

  • Discrete Cosine Transform (DCT) is effective for global signal variations but less so for local ones.
  • Wavelet Transform (WT) excels at representing signals with local variations due to wavelets' localized time support.
  • Electrocardiogram (ECG) signals, while low-frequency dominated, feature localized QRS complexes.

Purpose of the Study:

  • To investigate the effectiveness of DCT and WT for ECG data compression.
  • To explore combined transform techniques to overcome individual limitations.
  • To enhance visualization quality in compressed ECG data.

Main Methods:

  • Applying Discrete Cosine Transform (DCT) to ECG data.
  • Applying Wavelet Transform (WT) to ECG data.

  • Combining DCT and WT in two different hybrid approaches for ECG compression.

    • Main Results:

    • Individual DCT and WT show limitations in compressing ECG signals with localized features.
    • Combined DCT-WT techniques demonstrated improved compression efficiency.
    • Enhanced visualization quality was achieved with a reduced number of transform coefficients using hybrid methods.

    Conclusions:

    • Hybrid DCT-WT approaches offer superior ECG data compression compared to individual transforms.
    • Combining transforms effectively addresses the localized characteristics of ECG signals.
    • The proposed methods enhance visualization quality for compressed ECG data.
