c++ - OpenCv2.2 C++ filter2D

Question

我正在使用 OpenCv2.2 将 matlab 代码传输到 c++，在一个类似于 matlab 的函数 (conv2) 中，我使用来自

#include <opencv2/imgproc/imgproc.hpp>

问题是我收到的错误消息:

OpenCV Error: The function/feature is not implemented (Unsupported combination of source format (=4), and destination format (=4)) in getLinearFilter, file C:\opencv\sources\modules\imgproc\src\filter.cpp, line 3234

terminate called after throwing an instance of 'cv::Exception'

what(): C:\opencv\sources\modules\imgproc\src\filter.cpp:3234: error: (-213) Unsupported combination of source format (=4), and destination format (=4) in function getLinearFilter

第一次遇到这样的错误。所以，我真的不知道这是来 self 的安装还是来自代码。

代码:

void conv2(const Mat &img, const Mat& kernel, ConvolutionType type, Mat& dest)
{
    // fonction trouvée sur le site :

    // par  Timm Linder le 05/07/2011
  Mat source = img;
  if(CONVOLUTION_FULL == type) {
    source = Mat();
    const int additionalRows = kernel.rows-1, additionalCols = kernel.cols-1;
    copyMakeBorder(img, source, (additionalRows+1)/2, additionalRows/2, (additionalCols+1)/2, additionalCols/2, BORDER_CONSTANT, Scalar(0));
  }

  Point anchor(kernel.cols - kernel.cols/2 - 1, kernel.rows - kernel.rows/2 - 1);
  int borderMode = BORDER_CONSTANT;

  filter2D(source, dest, img.depth(), flip(kernel), anchor, 0, borderMode);

  //cvFilter2D(source, dest, img.depth(), flip(kernel), anchor, 0, borderMode);

  if(CONVOLUTION_VALID == type) {
    dest = dest.colRange((kernel.cols-1)/2, dest.cols - kernel.cols/2)
               .rowRange((kernel.rows-1)/2, dest.rows - kernel.rows/2);
  }
}

Answer 1

看着filter2d docs , -很明显，您不能使用 int32 Mats (type()==4)。

您必须转换为 CV_8U、CV_16U、CV_32F、CV_64F 之一

(也可以考虑更新你的 opencv。2.2 已经很旧了)
