A formulation is presented for the registration of two images in range. This is in contrast to the typical registration of images that occurs over their domain and ignores any exposure differences that might exist between the images. The registration is accomplished by approximating the camera's nonlinear comparametric function with a constrained piecewise(More)
An analysis of the conditions under which range registration was previously performed using a piecewise linear approximation to a comparametric function is presented. Stricter constraints are introduced which result in a better estimation of the exposure difference between two images of the same scene. Specifically, a positive slope constraint is imposed on(More)
