Astronomical instruments currently provide a large amount of data. Nowadays, a large part of these data are image frames obtained with receivers of increasing size. The scan of large astronomical plates using fast microdensitometers gives image frames of over 30000 X 30000 pixels. More and more ofte

In this paper a novel method for decomposing one-dimensional data sequences is developed. It is of the wavelet variety with important distinctions. A standard wavelet transform entails down-sampling the responses of two fixed structured filters to the sequence being decomposed to produce the half le
This paper presents a method for ECG data compression. The method is based on an orthogonal transform based on discrete Legendre polynomials. The use of such a transform provides several advantages for compressing ECG signals when compared with conventional Fourier or cosine transforms. We also have
