Many machine-vision applications require a pattern-finding tool (PFT), but traditional PFTs based on normalized cross correlation (NCC) techniques suffer major drawbacks. For example, the patterns to ...

Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly ...

Once a machine-vision system has acquired an image, a software image-analysis algorithm, known as a pattern-finding tool (PFT), must determine whether the image contains a particular pattern. While ...

Tile patterns in which the same shape is laid out without gaps can be seen on castle walls and chess boards in artificial objects, and in insect compound eyes and beehives in biology. Square tiles are ...
