detecting motion on opencv c++ (moving camera)

问题:

I'm doing a project for the university and I'm working with OpenCV (that is really awesome).

Now my problem is:
I have a video (.avi) and I have detected all the information I want to know about the blobs that suddenly appear in the RGB range between red and yellow. After I have realized a matrix that saves all the information about the pixel values, finally I create an image in the scale of red that represents the median pixel values.

The real problem is that the video is not static and the camera moves (not too much but it moves).
Can I calculate the x and y coordinates of the camera motion so I could shift the value of the matrix?

Who cares about your English? Till we understand your problem :) What you could really do is to give a shot at KLT motion detection that is implemented in OpenCV. Here is a link to KLT also known as optical flow If you can filter down the motion vectors limited to the blobs you can certainly get hold of the object you want to track. Even better to give KLT the objects initial coordinates/area to track. Have you checked OpenCV blobs library to get hold of the blobs? Here is the link
