A geometric centroid principle and its application.
A new concept of approximation for rigid point sets is suggested. As a necessary condition of optimality, the principle of the conjoint centroid is proved: to achieve a best approximation, certain co-sets must conjoin their centroids. The practical use of the centroid principle, and how it opens up a non-classical method of modelling various aspects of orientational disorder in crystals, is dem...
متن کاملLysogen stability is determined by the frequency of activity bursts from the fate-determining gene
The ability of living cells to maintain an inheritable memory of their gene-expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long-term cellular memory. In this study, we address the following question: in the absence of external perturbation, how long will a cell stay in the lysogenic state before spontaneously switching away from that stat...
متن کاملTowards object modelling by incorporating geometric constraints
This paper describes a new technique for global shape improvement based upon features’ positions and geometrical constraints. It suggests a general incremental, framework whereby constraints can be added and integrated in the model reconstruction process, resulting in an optimal trade-off between minimization of the shape fitting error and the constraints’ tolerances. The objects treated are in...
متن کاملA Novel Shape Signature of Geometric Mean of Segmented Centroid Distance Function to Track the Object through Fourier Descriptors
The process explicitly dedicated to estimate the path of the object as it moves along the region of scene in the image plane is principle of tracking. In other words it is a strategy to detect and track moving object through a sequence of frames. In this work, optical flow based on Horn-Schunk with Barren, Fleet and Beuchemin (BFB) kernel has been employed to estimate the motion vectors. The pe...
متن کاملObject Space Segmentation by Geometric Reference Structures
Segmentation of an object space by binary radiation sensors and geometric reference structures is studied in this paper. Given a family of binary radiation sensors and a geometric reference structure, we refer to the set of sensor states induced by a source at point as the signature of . We study the segmentation of an object space into signature cells and prove near-optimal bounds on the numbe...
