qitianyu-0403 / opencvimage Goto Github PK

I did a quick test and qt and opencv worked. For this project, the compile passed, but the runtime reported the error. Can you help me see what the problem is?

Hello, could u release your source code for further research?

Many people say can't find the code. Here I introduce the structure of this project.
You can find all the source code in the /open_image folder in https://github.com/QiTianyu-0403/OpenCVImage, /open_image is the root directory of the code. And you will find the main.cpp.
