3X3的结构元素如图

internal gradient=原图像减结构元素对元素的侵蚀结果

效果如图，左面为原图，右面为效果图

在图片已经导入的情况下可以使用该imageJ marco代码

height=getHeight();
    width=getWidth();
    new_image=newArray(width*height);
    temp=0
    for (i=0;i<width;i++){
    	for (ii=0;ii<height;ii++){
    		v=getPixel(i,ii);
    		new_image[temp]=v;
    		temp+=1;
    	}
    }
    
    for (i=1;i<width-1;i++){
    	for (ii=1;ii<height-1;ii++){
    		zerozero=getPixel(i-1,ii-1);
    		twozero=getPixel(i+1,ii-1);
    		oneone=getPixel(i,ii);
    		zerotwo=getPixel(i-1,ii+1);
    		twotwo=getPixel(i+1,ii+1);
    		
    		
    		if (zerozero==255 && twozero==255 && oneone==255 && zerotwo==255 && twotwo==255)
    			new_image[i+ii*width]=255;
    		else
    			new_image[i+ii*width]=0;
    }}
    for (i=0;i<width;i++){
    	for (ii=0;ii<height;ii++){
    		v=getPixel(i,ii)-new_image[i+ii*width];
    		setPixel(i,ii,v);
    	}
    }
