In Structure from Motion algorithms, the error in the estimated motion aaects each reconstructed 3D point in a systematic way. This paper attempts to isolate the eeect of the motion error (as correlations in the structure error) and shows theoretically that these correlations can improve existing multi{frame Structure from Motion techniques. Finally it is shown that new experimental results and...
