Paper Abstract

The paper deals with methods of interpretation of features of vibration signals, which make it possibly to detect changes of these features. Considered signals are mainly recorded during varying conditions of rotating machinery. Signal features are coded in matrices that are similar to image data. Matrix is considered as dynamic scene and signal features are treated as that scene objects. These methods make it possible to identify variability of features that are strictly related to changes of technical state of the machinery. Scene analysis may be carried out with the use of methods of image analysis. Examples of these methods are lines detection or syntactic description. There is also an example of application of technical state observers.
