<P>我复制“蓝通道”为“蓝副本通道”,用色阶调整得到白色选区,抠出这个图。<IMG onmousewheel="return bbimg(this)" style="WIDTH: 524px" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200605/20060530132525126.jpg" onload="javascript:if(this.width>screen.width-500)this.style.width=screen.width-500;" border=0 pop="按此在新窗口浏览图片"></P>
<P>加了一个深蓝色的背景,大家看,在这个背景的衬托下植物的边缘明显有呈现出一种灰白色。<BR><BR><IMG onmousewheel="return bbimg(this)" style="WIDTH: 524px" alt=按此在新窗口浏览图片 src="http://www.cgfancy.com/Article/UploadFiles/200605/20060530132526683.jpg" onload="javascript:if(this.width>screen.width-500)this.style.width=screen.width-500;" border=0></P>
<P>在这个图里,简单地述说一下修边中三个命令:去边、移去黑色杂边、移去白色杂边。</P>
<P><IMG onmousewheel="return bbimg(this)" style="WIDTH: 524px" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200605/20060530132526924.jpg" onload="javascript:if(this.width>screen.width-500)this.style.width=screen.width-500;" border=0 pop="按此在新窗口浏览图片"></P>
<P>用“去边”后,灰白的边缘明显除掉没有了,如图所示:<BR><BR><IMG onmousewheel="return bbimg(this)" style="WIDTH: 524px" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200605/20060530132526694.jpg" onload="javascript:if(this.width>screen.width-500)this.style.width=screen.width-500;" border=0 pop="按此在新窗口浏览图片"></P>
<P>用“移去黑色杂边”命令,大家看,黑色移去了,边缘白色像素显得更白了<BR><IMG onmousewheel="return bbimg(this)" style="WIDTH: 524px" alt="" src="http://www.cgfancy.com/Article/UploadFiles/200605/20060530132526991.jpg" onload="javascript:if(this.width>screen.width-500)this.style.width=screen.width-500;" border=0 pop="按此在新窗口浏览图片"></P>
<P>现在用“移去白色杂边”命令,大家看,边缘白色像素移去了,边缘的黑色像素加强了,轮廓更为清晰了。只是此处是植物而不是发丝,边缘的黑色像素加强了却显得别扭了,呵呵。。。</P>

<P>在图片处理中,这三个命令用到恰到好处,都能取得很好的效果!</P>
<P>大家亲手做做,各自琢磨下,会有收益的!</P></TD></TR></TBODY></TABLE><BR><script language="JavaScript" src="http://www.16xx8.com/bbs/10.js"></script><BR> 不行!缺点!
