Revisiting Hartley's Normalized Eight-Point Algorithm
Hartley’s eight-point algorithm has maintained an important place in computer vision, notably as a means of providing an initial value of the fundamental matrix for use in iterative estimation methods. In this paper, a novel explanation is given for the improvement in performance of the eight-point algorithm that results from using normalized data. It is first established that the normalized al...

متن کاملThe Eight-Point Algorithm
This note describes a method for computing estimates of the rigid transformation G and estimates of the coordinates of a set of n points P1, . . . ,Pn in the two camera reference frames from the n pairs (x1,y ′ 1), . . . (xn,y ′ n) of noisy measurements of their corresponding images. The transformation G is called camera motion, and the point coordinates Xi, Xi of the world points in the two re...
متن کاملIn Defense of the Eight-Point Algorithm
The fundamental matrix is a basic tool in the analysis of scenes taken with two uncalibrated cameras, and the eight-point algorithm is a frequently cited method for computing the fundamental matrix from a set of eight or more point matches. It has the advantage of simplicity of implementation. The prevailing view is, however, that it is extremely susceptible to noise and hence virtually useless...
متن کاملA statistical rationalisation of Hartley's normalised eight-point algorithm
The eight-point algorithm of Hartley occupies an important place in computer vision, notably as a means of providing an initial value of the fundamental matrix for use in iterative estimation methods. In this paper, a novel explanation is given for the improvement in performance of the eightpoint algorithm that results from using normalised data. A first step is singling out a cost function tha...
