Full Sheet Control Using Steerable Nips

Full Paper Sheet Control Using Hybrid Automata

Some high speed color printers require that the sheets be accurately controlled in order to achieve a precise alignment of colors. To accomplish this goal a steerable nips mechanism has been proposed as the actuator. This steerable nips mechanism allows the sheet to be precisely controlled in longitudinal, lateral and skew directions. In this paper we develop a control strategy based on hybrid ...

Fabric Defect Detection Using Steerable Pyramid

In this paper, a novel idea is proposed for fabric defect detection. Defects are detected in the fabric using steerable pyramid along with a defect detection algorithm. Various steerable pyramid of four size 256*256, 128*128, 64*64, 32*32 and with four orientation bands 0,45, 90, 135 are used. Utilizing a Steerable pyramid proved adequate in the representation of fabric images in multi-scale an...

Motion Feature Detection Using Steerable Flow Fields

The estimation and detection of occlusion boundaries and moving bars are important and challenging problems in image sequence analysis. Here, we model such motion features as linear combinations of steerable basis flow fields. These models constrain the interpretation of image motion, and are used in the same way as translational or affine motion models. We estimate the subspace coefficients of...

Image Watermarking Using the Steerable Pyramid Transform

The protection of intellectual property rights became recently a pressing need especially with the rapid growth of transmission techniques. In this paper, we present as a copyright protection method, a non-blind watermarking technique based on the image content. We choose edges for watermark insertion. Our approach uses the steerable pyramid decomposition: the image is decomposed into a set of ...
