A method and system for applying pipeline architecture to discrete cosine transform and inverse discrete cosine transform. In some arrangements, the temperature andor humidity within the housing will be monitored. Operating data are calculated based on the received monitoring signal. Furthermore the method may optionally also perform label propagation taking into account keypoint tracking. According to the die for extrusion molding of a honeycomb, a dimensional error of the die is possible to be eliminated, a stable force of extrusion friction is possible to be maintained, both extrusion moldability and abrasion resistance are possible to be excellent, and additionally an adjustment of the die at the time of extrusion molding can be performed easily.
