Vision-based document segmentation identifies one or more portions of semantic content of a document. The integrated device is connected to various peripheral devices with different interfaces and controlled by corresponding external port signals. Means for calculating the variance for each pixel of the high-frequency image. The nonwoven fabric is provided with an elastic member extending in the longitudinal direction for exhibiting longitudinal shrinking force. Furthermore the present invention relates to the process for making a silicone release coating with improved adhesion to paper and polymeric substrates. A portion of the blind vias in the power layers are grouped together to form a cluster of blind vias.
