文摘
- •
In this paper, the shearlet transform is directly applied to detect surface defects of magnetic tile.
- •
A novel threshold surface method is proposed to modify the shearlet coefficients.
- •
The method we proposed can extract the defect area effectively.
- •
The method we proposed can recognize tiny defects from low-contrast images with complex background.
- •
The method we proposed achieves a high detection rate.
