The Extraction of Dust Tire Impression on Clothes Using Polarization and Color-Separation Photography

This paper studied the possibility and the method of polarization and color-separation photography by digital camera. The dust tire impression on different color clothes were extracted with different photography methods and the results of experiment shows that the desired result can be obtained using polarization and color-separation photography. Compared with chemical reagents appear method, polarization and color-separation photography belongs to nondestructive test method.
