The Complication of Spectral Analysis Based on Fourier Transform in the Tire X-ray Detection

There are many ways to have the quality inspection of the meridian tires, spectrum analysis is the Image analysis method in frequency domain, the primary function is to obtain the textural features of images in frequency domain. Fourier transform can change signals from time domain to frequency domain and get each frequency component, that is decomposed signals into different frequency spectrum. Then we can have image processing and evaluate whether the tires have defects or not. The experimental result shows that the spectral analysis based on Fourier transform of the tire X-ray detection can greatly reduce the workload, and improve the efficiency of the tire X-ray detection.
