Abstract :
The fractal dimension or complexity of physiological signal is calculated with a novel tool, dot counting dimension (DCD) in this paper. The definition and algorithm of DCD are given out. DCD of nine arrhythmia records are calculated and linear result of DCD is achieved. The algorithm of DCD is useful for processing physiological signal because of its implementing easy with less calculation, and fast calculation velocity, and the algorithm of DCD does not need too much more data for achieving convergence.
