X-ray inspection image enhencement using shearlet transform
In automatic X-ray inspection, to denoise and enhance characteristics is a very important issue for application, especially the images used to inspect the wires in chips. Because the methods used to enhance or denoise may degrade the characteristic of the wires which can be seen as curves such that the efficiency is not enough. Shearlet has been approved of its perfect performance on curve description. In this paper, the method is applied and the method of coefficient modification is used. As a result, it shows that the wires are effectively enhanced while the noise is also attenuated.
