The goal of this work aims at the estimation of the epipolar geometry, namely the fundamental matrices and tensors of a group of images. After, the basic concepts of the epipolar geometry are shown, a software is presented that addresses the following problem: given N images of the same size, the list of possible matches of any pair and of any triple of images together with the fundamental matrix (of any pair) and the tensor (of any triple) is calculated. The final result will consists of ascii files with this information.
