I have to rewrite the source code to new version of OpenCV and I have problem with functions and class cvLoad, cvarrToMat and IplImage which doesn't exist in new version of OpenCV.

My old code is:

cv::Mat load(string path) {
   IplImage * imgT = (IplImage*) cvLoad(path.c_str());
   return cvarrToMat(imgT);
}

I get this error output while compiling:

error: 'IplImage' was not declared in this scope

The data which are loaded are depth maps from UTKinect 3D dataset. Here is example of xml file: 

<?xml version="1.0"?>
<opencv_storage>
<depthImg190 type_id="opencv-image">
  <width>320</width>
  <height>240</height>
  <origin>top-left</origin>
  <layout>interleaved</layout>
  <dt>w</dt>
  <data>

  • I suppose, you (just) want to load (or read) an image from a file!? For example, have a look at [`imread`](https://docs.opencv.org/4.1.0/d4/da8/group__imgcodecs.html#ga288b8b3da0892bd651fce07b3bbd3a56). – HansHirse Jun 28 '19 at 12:54
  • I use it for loading depth binary image of UTKinect Action 3D dataset. – gulliver Jun 28 '19 at 12:56
  • Hm, ok. You should add all information you have, e.g. regarding the header, to your question. If possible, you may also add some sample data. From the quite simple code, I assumed some simple image loading operation. Does `cvLoad` do something automagically to these Kinect data, which wouldn't be also covered by `cv::imread`? – HansHirse Jun 28 '19 at 14:57
  • Yeah, good idea, I updated the article. Sorry for mystification, the data are stored in xml file. – gulliver Jun 28 '19 at 20:24
  • and for information, I tried the imread, no works. – gulliver Jun 28 '19 at 20:26
  • Have a look at [this answer](https://stackoverflow.com/a/44056881/11089932) and the link inside. Hopefully, that'll help you! – HansHirse Jun 29 '19 at 20:12
