Based on the definition of wavelet spectrum of the maximal overlap discrete wavelet transform, we propose a novel algorithm for determining the local singularity exponents, which provides the local scaling information of interest, and construct a singularity- spectrum- like histo gram to describe the global statistical distribution of the local singularity strengths. The validity and efficiency are verified by numerical experiment and application to real heart rate data.
