In this paper, we propose an expert-system based parallel multi-1-dimensional block matching algorithm (ESPM-1D-BMA) for motion estimation (ME). Instead of the conventional 2D block matching, we employ the parallel multi-1D blocks matching to improve the computing speed. To improve the ME accuracy, we design a knowledge base and inference engine to determine the true motion vector (MV) from the...

General SFM methods give poor results for images captured by constrained motions such as planar motion of concentric mosaics (CM). In this paper, we propose new SFM algorithms for both images captured by CM and composite mosaic images from CM. We first introduce 1D affine camera model for completing 1D camera models. Then we show that a 2D image captured by CM can be decoupled into two 1D image...

We have introduced a Ren-1D targeting vector into embryonic stem cells containing the two highly homologous mouse renin genes Ren-1D and Ren-2. Using a polymerase chain reaction (PCR) screen designed to detect targeted integration at Ren-1D and Ren-2, we isolated 15 targeted embryonic stem cell clones, all of which had undergone a gene conversion event at the Ren-1D locus. We did not isolate an...

Camera calibration is a necessary step to extract 3D metric information from 2D images. 1D object-based camera calibration has recently received attention because there is no self-occlusion problem for a 1D object. In this paper, an adaptively weighted 1D calibration algorithm with high accuracy is presented. The innovation and contributions of such an algorithm are two-fold: one is that data n...

This paper attempts to make accessible a body of ideas surrounding the following result: Typical families of (possibly multi-model) 1-dimensional maps passing through “Misiurewicz points” have invariant densities for positive measure sets of parameters. The simplest paradigms of chaotic behavior in dynamical systems are found in uniformly expanding and uniformly hyperbolic (or Anosov) maps. All...

Two decades ago, Sadovskii found an exact solution of a model describing a pseudogap in electron energy spectrum (first introduced by Lee, Rice and Anderson). The discovery of a pseudogap in high-Tc superconductors has revived the interest to his exact solution. I review the model with the emphasis on physical content, point out an error in the original Sadovskii’s solution and explain which pr...

To realize a one-dimensional (1D) system with strong spin-orbit coupling is a big challenge in modern physics, since the electrons in such a system are predicted to exhibit exotic properties unexpected from the 2D or 3D counterparts, while it was difficult to realize genuine physical properties inherent to the 1D system. We demonstrate the first experimental result that directly determines the ...
