OpenCV Matrix To Binary Image

Question

I have client and server, have an image in client and I want to send this to server. That image is in cv::mat format. Therefore I need to convert this matrix to binary. I have tried memcpy(binImage,matImg.data,sizeof(matImg.data) binImage's format is char*

How can i convert this matImg to binImg? I don't have any experience about OpenCV.

See the answer here stackoverflow.com/questions/20314524/… might be helpful. — Haris

The following should do the trick:

memcpy(binImage, matImg.data, matImg.step.p[0]*matImg.rows)

However, I think you can avoid the copy and work directly with matImg.data.

@Darth This is only the instruction for memcpy. Did you allocated binImage with enough space ? Did you initialized matImg ?
