Comparison of methods of compression ECG-signals for problems telemedicine

Представлена сравнительная оценка различных методов сжатия биометрических сигналов, таких как ЭКГ, ЭЭГ и им подобных для задач передачи телемедицинской информации в условиях ограниченной пропускной способности каналов связи. Проведен сравнительный анализ методов сжатия телеметрической информации, таких как: дискретное косинусное преобразование первого и второго типов, дискретное синусное преобразование, быстрое преобразование Фурье и Вейвлет преобразование, и даны рекомендации по эффективности их применения для задач обработки биометрических сигналов.The comparative evaluation of different methods of compression of biological signals such as ECG, EEG, and the like for telemedicine transmission problems in situations of limited network bandwidth. Identified evaluation parameters of compression methods of biological signals. A comparative analysis of methods, such as discrete cosine transform, discrete sine transforms, fast Fourier transform and wavelet transform, and recommendations on their performance for ECG processing tasks. It has been shown that method of Discrete Cosine Transform showed better compression rate as compared with other methods, but the method only discrete method of Discrete Cosine Transform in type II (DCT-II), gives the standard deviation of less than one, and is most suitable for use in a telemedicine system. These methods can be used in modern telemedicine center for family medicine, which have a low cost with sufficient mobility applications
