Abstract
En 中文
Nowadays, telemedicine is more and more required. Signal compression is a critical step in telemedicine systems. In this paper, we suggest the use of orthogonal polynomials for electrocardiogram signal compression. The algorithms developed were tested using the Massachussets Institute of Technology's signal database. The results of our tests were compared to those of well-established methods and were, in some cases, better and comparable in most cases. (C) 2009 Elsevier Masson SAS. All rights reserved.
