Application of Local Histogram Clipping Equalization Image Enhancement in Bearing Fault Diagnosis

Application of Local Histogram Clipping Equalization Image Enhancement in Bearing Fault Diagnosis

Aiming at the problem that the time-frequency image of bearing fault characteristics is relatively weak and difficult to identify. This paper presents a time-frequency analysis method of local maximum synchrosqueezing transform based on image enhancement. Firstly, the instantaneous frequency of the...
