Claim 4:
5. The failure diagnosis method as claimed in claim 4, wherein a formula for calculating fusion of the high-frequency component images in Step 3 comprises:
when the high-frequency components are processed through the region-based property measurement, a formula for calculating region energies corresponding to two images is as follows:

El(n,m)=Σn′∈J,m′∈kwl(n′,m′)[Lpl(n+n′,m+m′)],

wherein E represents a region energy of an lth layer, LPl represents an image of the lth layer, w represents a weight coefficient, (n, m) represents a center point of a region, and J, K define a size of a range of the region, (n′, m′) represents a point moving within the range of J, K within the region, wherein, to calculate a matching degree of the corresponding region between the two images, a registration process is performed, a matching threshold is defined, and a mathematical model for the matching degree is represented as follows:, M
