yellow streak

• To make the yellow streak look as if it is on the field , the operator continually refines the colors in the broadcast feed over which the computer should paint the line ( grassy greens ) and those it should not ( players ' skin and uniforms )
  为了让这条黄线看起来像画在球场上，操作员需根据电脑应该画线的区域（草皮的绿地） ，以及不应该画线的区域（球员的皮肤和制服） ，不断调整播送内容的颜色。
