ImageMagick和OpenCV文件格式互转

图像处理领域两大开源库OpenCV和ImageMagick，前者偏重于智能识别算法，后者偏重于艺术加工

两个库使用的图像格式不同，相互转换的方法如下：

OpenCV -> ImageMagick

Image Ipl2Magick(IplImage* iplImage){   Image mgk(iplImage->width, iplImage->height, "BGR", CharPixel, (char *)iplImage->imageData);   return mgk;}

ImageMagick -> OpenCV

void Magick2Ipl(Image magicImage, IplImage* cvImage){   int width= magicImage.size().width();   int height = magicImage.size().height();   byte* blob= new byte[cvImage->imageSize];   magicImage.write(0,0, width, height, "BGRA", MagickCore::CharPixel, blob);   memcpy(cvImage->imageData, blob, cvImage->imageSize);   delete [] blob;}

需要注意OpenCV创建图像要创建成4通道的图像

IplImage* cvimg =  cvCreateImage(cvSize(...,...), IPL_DEPTH_8U, 4);
