A New Approach to an Old Problem: The Reconstruction of a Go Game through a Series of Photographs

Abstract

Given a series of photographs taken during a Go game, we describe the techniques we successfully employ for pinpointing the grid lines of the Go board and for tracking their small movements between consecutive photographs; then we discuss how to approximate the location and orientation of the observer's point of view, in order to compensate for projection effects. Finally we describe the different criteria that jointly form the algorithm for stones' detection, thus enabling us to automatically reconstruct the whole move sequence.
