  We study the nonlinear generalization of the classical multiview variety,
which is a fundamental concept in computer vision. In this paper, we take the
first comprehensive step to develop the nonlinear analogue of multiview
varieties. To this end, we introduce a multigraded version of the saturated
special fiber ring. By applying this tool, we are able to compute the
multidegrees of several families of nonlinear multiview varieties.
