Abstract:   (262 Views)
In addition to medical recognition applications, X-ray CT-scan images are increasingly found to have more innovative and widespread applications. Due to the ability of producing high resolution and high contrast images from soft tissues with low attenuation coefficients, the usage of X-ray micro-focus source, which has a very small focal point (in the range of micrometer), plays an important role in those new applications. Since employing non-original knots in hand-knitted carpet reduces the carpet quality and the originality of knots cannot be visually recognized, in this research, a method has been introduced for recognition of the 3D structure of hand-knitted carpet using CT-scan images provided by micro-focus X-ray source. The images obtained by inverse Radon transform can even show the smallest units in the inner structure of the finest hand-knitted carpets. This method is a powerful device to recognize the originality, to inspect the structure and to study the impacts of different parameters on the structure of hand-knitted carpets and also for other applications which need scrutiny of 3D textiles.
