FFT used for fabric defect detection based on CUDA

Aiming at the problem for the online real-time detection of fabric defect, this paper uses the method of Fast Fourier Transform based on CUDA to detect the fabric defect, This method adopts multi thread parallel implementation of FFT algorithm for fabric defect detection on the GPU platform. Compared with the simulation of FFT algorithm based on CPU, the result shows, the algorithm proposed in this paper can significantly shorten the time of detection on the basis of ensuring the correct detection rate. This algorithm provides a theoretical basis for the online detection of fabric defects.
