Storing motion vectors from calculated optical flow in a practical way which enables reconstruction of subsequent frames from initial keyframes

I am trying to store the motion detected from optical flow for frames in a video sequence and then use these stored motion vectors in order to predict the alrea

Detecting camera motion with opencv

I am working on drone stabilization close to walls using a camera. For this to work I need to extract the motion the camera makes relative to the wall. For now

How to decode mpeg motion vector using OpenCV in C++?

I want to decode the MPEG motion vectors using OpenCV in C++. Is there any function in OpenCV through which we can get this? Brightness may not be constant thro

Set histogram of size surf descriptors

I'm trying to compute a motion histogram of the region around surf descriptor, and i don't know if there is a method to compute the size of the histogram (how m
