Cannon, Thomas Michael | Digital image deblurring by nonlinear homomorphic filtering (CSTD-74-004) | This report is concerned with the digital estimation of the frequency response of a two-dimensional linear system through which images have been passed and blurred. Almas t no a priori Knowledge concerning the system is required, and only one blurred image is necessar\d for a successful estimation. ... | Computer animation | 1974-08 |

Mattis, Daniel C. | Effect of band structure on ferromagnetism* | We extend Nagaoka's study of the ferromagnetism of nearly half-filled bands in the infinite-repulsion limit of the Hubbard model by including next-nearest-neighbor tight-binding overlap matrix elements K2. Particles can now get past one another, even in one dimension. We find corroboration of Nagaok... | Eigenstates; Spin waves | 1974-08 |
