  Running time of the light field depth estimation algorithms is typically
high. This assessment is based on the computational complexity of existing
methods and the large amounts of data involved. The aim of our work is to
develop a simple and fast algorithm for accurate depth computation. In this
context, we propose an approach, which involves Semi-Global Matching for the
processing of light field images. It forms on comparison of pixels'
correspondences with different metrics in the substantially bounded light field
space. We show that our method is suitable for the fast production of a proper
result in a variety of light field configurations
