Abstract
In order to measure the magnetic tile size automatically, a method based on sub-pixel image segmentation was proposed. After getting the image contour based on dynamic threshold, the sub-pixel edge of magnetic tile through the second derivative edge extraction was got. At the last, the fitting method about magnetic tile size and the arc radius was produced.
