Does high-degree polynomial approximation improve data compression of ECGs compared to discrete cosine transform?
High-degree polynomial approximation provides superior ECG data compression compared to discrete cosine transform while maintaining acceptable signal quality.
Philips et al. (1992) studied this question.
