【Abstract】 Template matching and DCT are comprehenssively used to compress ECG data. Template mathching is used for QRS wave because of its plentiful high frequency parts and relatively regular form: while DCT is used to compress wave P and T, which contain only low frequency parts. Therefore good fidelity and high compression ratio are abtained.更多还原
