@Shivani1796 have you solved this issue? I have the same problem

[jdriscoll319]

You need to edit the file to have #include <opencv2/imgcodecs.hpp> and replace all of the CV_LOAD_IMAGE_[x] with cv::IMREAD_[x] e.g. CV_LOAD_IMAGE_GRAYSCALE -> cv::IMREAD_GRAYSCALE CV_LOAD_IMAGE_[x] is from an older version of openCV and has been deprecated

I have both opencv versions installed, is there a way to point to opencv4?

Please ignore, It seems like DSO is using opencv3. If you have multiple versions of opencv installed in your system just point to the right version in the CMakeLists.txt file .

for me it was in line 23 ; find_package(OpenCV 3 QUIET)
