This article uses the principle of Wavelet transformation and Quad-tree structure to find the best jumper points of embroidery machine. Embroidery want the image to be cut into four equal parts. Furthermore, to judge each part if there exist two object for connection jumper point selection. For special case, the four parts divided will be extended until the best jumper point were found. According to the simulation results, our method is evidently an effective and high quality method for sewing machine for embroidering purpose.
