Example embodiments provide various techniques for updating an old data structure configured to store metadata associated with database systems. The sampling positions of colors used to generate correction parameters are acquired. Given the defined loops or video clips, the user next forms a remix of the selected songvideo work using those components. In a particular embodiment, the interference image is acquired using a color camera and the three-color channels are processed separately, recomposing the final image. The treated laminate also has an air permeability through the treated laminate of at least 0.
