按照上篇講的套路，我們再來實現一個例子
這裏有如下原圖
找出所有的格子
一、選取區域
二、創建模板
創建後，模板的座標爲（0,0），即左上角
三、尋找模板
代碼：
* Many dies are typically etched on a wafer. Before the single
* dies can be picked by a die bonder and placed onto a lead
* frame, they must be diced from the wafer. Mirror dies are
* used to determine the parameters of the dicing process.
* Here, the positions of the mirror dies are determined using
* shape-based matching.
