#includevoid whiteblack(int *selimage, int height, int width, int *twovalimage){int indexh,indexw; int val1=0,val2=255; //求取阀值 for(indexh=0; indexhval1)
val1 =*(twovalimage + width*indexh + indexw);//val1:maxvalue} val1 = val1 - (val1 - val2)/3;
//calculate limit value //二值化 for(indexh=0; indexh < height; indexh++)for(indexw=0; indexw < width; indexw++){ /*tr=*(selimage + width*indexh + indexw);

CImage image;
//加载BMGimage.Load(L"");
//宽image.GetWidth();
//byte 字节二进制image.GetBits();
//高image.GetHeight();
