An algorithm is presented for designing directional gabor filters for getting every texture layer of multi-layers texture tyre image,which is formed when X-rays scan the different direction array of tyre hanging-lines.Having the features of the pseudo periodicity and different directions,the space arrays and array direction of hanging-lines separately relate the maximums of ring features and wedge feature of Fourier coefficient.The wedge feature maximum of Fourier coefficient gives the direction of every texture layer of X-ray tyre image;the algorithm will map the ring feature maximum of Fourier coefficient to the scale parameter of gabor filter,and then automatically search the refined scale and accurately direction parameters in the guide line of energy convergence.Finally,the experiment results show the algorithm is highly efficient to extract every layer texture of X-ray tyre image.
