Abstract
A method of recognizing an embroidery outline and applying a stitch group. In the first step, the angle of rows of stitches is determined based on the coordinate sequence of the stitches. The left and right boundary points are then determined to be those stitches that exist along the ends of these rows and from the vertex of an angle change in the stitching. The lines between these left and right points are then used to determine the outline by expanding the lines into rectangles. A statistical analysis is then performed along the rectangle edges and a curve smoothing algorithm is used the render the final shape.
