Detailed description

The 7-point algorithm is not normalized.

According to Richard I. Hartley. 1997. In Defense of the Eight-Point Algorithm. IEEE Trans. Pattern Anal. Mach. Intell. 19, 6 (June 1997), 580-593. , the performance of the unnormalized version is much worse than the normalized version, though the paper talks about the 8-point algorithm, it applies also to the 7-point algorithm.
