Classification: CPC G | IPC G

Claim 5:
6. The failure diagnosis method as claimed in claim 4, wherein a formula for fusion calculation for the low-frequency component images in Step 3 comprises:
fusing the low-frequency components based on weighted averaging, and given that k, α, β is a weighting factor, F is an output result, then a fusion principle is:

F(j,k)=(A(j,k)+k×B(j,k)+ . . . +kn×B(j,k))×α−, (A(j,k)−k×B(j,k)− . . . −kn×B(j,k))×β

wherein by fusing the low-frequency components of images A and B, a new image of j layer is formed, wherein details and a denoising property in the image of the layer is balanced.
