The First Image is the main input While the second input is the Template to be match

第一个图像是主输入,而第二个输入是要匹配的模板

The thing that what i want the code to do is detect the G clef and the horizontal staff line of it and remove it, can anyone help me please.

我想要代码做的事情就是检测G谱号及其水平人员线并将其删除,任何人都可以帮助我。

Don't flood fill rectangle, just put there staff image without G clef.

不要淹没填充矩形,只是放在没有G谱号的员工图像。
