 What is StereoFlow

StereoFlow is a software for reconstructing 3D scenes from two projective images. 

 

We have implemented a partial differential equation in order to find correspondences between two images (refer to our papers for better understanding the method). We make use of the epipolar geometry (Fundamental Matrix) for better estimating the correspondences. The result is the flow, U and V (displacement in x and y), from the first image to the second one.

 

With this program there are two more applications: one for analysing the epipolar lines and the other one for reconstructing the scene.

 

StereoFlow is developed under XMegaWave.
