Abstract A common approach to estimation of dynamic economic models is calibrate a subset model parameters and keep them fixed when estimating the remaining parameters. Calibrated likely affect conclusions based on model, but time often makes systematic investigation sensitivity calibrated infeasible. I propose simple computationally low-cost measure other objects interest In main empirical app...

Structure from motion (SfM) is the problem of computing the 3D scene and camera parameters from a video or collection of images. SfM can be further classified as calibrated and un-calibrated. In calibrated SfM, the internal camera parameters are known. This is a much easier problem than the un-calibrated case, where these parameters are unknown. Solving for the internal camera parameters are kn...
