help to send imagen and data from opecv c++

I'm newbie in this thing of dll's or plugins so if someone could guide me on right path.

The problem is the i want to use vizard with opencv, and first i tried the opencv for python, but some of the methods of opencv are not well implemented on python like the c++ version, and also the performance is better on c++, and there are more example of programs implemented on c++.

So my question what is the best way to send a image from the camera with also data of what i'm getting, for example the face detection of opencv i want to send the image that i get from the camera and also the numer of faces detected with the position of each face where is located, and receive that on vizard.

If you can send data over the network using OpenCV then you could use the Python socket module to receive the data in Vizard.

A TCP socket is probably the best method to send image data over the network. If the image is small enough, then it might work with UDP sockets. UDP sockets have a maximum message size, that's why it will only work with small images.

Compress the image to jpeg and send the data. In Vizard, you can use the <multimedia:image>.loadBuffer command to load it directly from memory.
