Multi-scale morphological decomposition is a decomposition method being proposed based on the basic theory of multi-scale morphology. Using from small to large scale of structural elements to deal with different “Scale domain”, thus the original signal is decomposed into a complete set of orthogonal In multi-scale mathematical morphology operation is the essence of it. This article combines multi-scale decomposition with the information entropy theory, put forward a kind of feature extraction method based on multi-scale morphological spectrum entropy, with multi-scale morphological spectrum entropy (multi-scale morphological spectrum entropy, multi-scale morphological singular spectrum entropy) as a feature vector can effectively distinguish between different running state of rolling bearings, and through the simulation and experiment validation.
