Telephoto Lens

Cameras with telephoto lens are usually used to recover details of an object that is either small or located far away from the cameras. However, the calibration of this kind of cameras is not as accurate as the one of cameras with short focal lengths that are commonly used in many vision applications. This paper has two contributions. First, we present a first-order error analysis that shows the relation between focal length and estimation uncertainties of camera parameters. To our knowledge, this error analysis with respect to focal length has not been studied in the area of camera calibration. Second, we propose a robust algorithm to calibrate the camera with a long focal length without using additional devices. By adding a regularization term, our algorithm makes the estimation of the image of the absolute conic well posed. As a consequence, the covariance of camera parameters can be reduced greatly. We further used simulations and real data to verify our proposed algorithm and obtained very stable results.

The semidiscrete and fully discrete discontinuous mixed covolume schemes for the linear parabolic integrodifferential problems on triangular meshes are proposed. The error analysis of the semidiscrete and fully discrete discontinuous mixed covolume scheme is presented and the optimal order error estimate in discontinuousH(div)and first-order error estimate inL2are obtained with the lowest order Raviart-Thomas mixed element space.

Self Formation

Herder develops a number of very important principles both in meta-ethics and in first-order morality. In meta-ethics he argues for a form of sentimentalism, but a form of it that acknowledges a role for cognition in the sentiments involved and which emphasizes their radical variability between periods and cultures. He also invents a “genetic” or “genealogical” method predicated on such variability and applies it to moral values in particular in order to make them better understood. And finally, he develops an ambitious theory and practice of moral pedagogy that rests on his sentimentalism and which accordingly focuses on causal influences on moral character formation, such as role models and literature. In first-order morality he invents an important pluralistic form of cosmopolitanism to replace the more usual but problematic homogenizing cosmopolitanism of the Enlightenment; an influential ideal of individual Bildung, or self-formation; and a distinctive ideal of humanity.
