WebJun 1, 2024 · In this paper, we propose a promising approach based on General Linear Chirplet Transform (GLCT) to automatically classify the moving targets. Precisely, we extract pseudo-Zernike features from the TF obtained via GLCT, and use k-Nearest Neighbors (k-NN) for classification. The objective of using k-NN is to show the … WebDec 30, 2024 · The Generalized Linear Chirplet Transform (GLCT) Method Although the CWT and PWVD methods can be considered as some of the most advanced time–frequency methods in gear fault diagnosis, they have particular drawbacks for analyzing gearbox signals as previously described. easy homemade family recipes
