Novel detection method for infrared small targets using weighted information entropy

This paper presents a method for detecting the small infrared target under complex background. An algorithm, named local mutation weighted information entropy （LMWIE）, is proposed to suppress background. Then, the grey value of targets is enhanced by calculating the local energy. Image segmentation based on the adaptive threshold is used to solve the problems that the grey value of noise is enhanced with the grey value improvement of targets. Experimental results show that compared with the adaptive Butterworth high-pass filter method, the proposed algorithm is more effective and faster for the infrared small target detection.

Introduction to Thermo-Photo-Electronics

Building the foundations of Thermo-Photo-Electronics became possible only after the correction of thermodynamic errors in the traditional theory of semiconductor Electronics and Photo-Electronics.It is these errors that determined the output of the asymptotics of the operating parameters of semiconductor electronic devices,in particular,both the saturation of the limiting clock frequency of processors,and the saturation of the efficiency of both thermoelectric and photoelectric converters.But in semiconductors,although these thermodynamic errors manifested themselves not only in the instrumental,but also in the technological aspect,they could not prohibit semiconductor Electronics itself,unlike Electronics based on other materials.It’s just that a number of qualitative mistakes were made in the theory of semiconductor devices and photo devices.In this work,it is shown that the energy band diagram of semiconductor contacts itself was constructed with a significant omission-without taking into account the temperature force on the contact.At the same time,because of the incorrect calculation of currents according to the outdated formulas of Richardson-Langmuir-Deshman,there were also PROHIBITIONS.So the practitioners compensated for the errors of the theory with“empirical corrections”.So electronics engineers often made devices not according to a strict theory(which simply did not exist until now),but on a hunch and according to empirical local laws.And only the correction of the historical mistakes made it possible to expand the phenomenology of the description of processes in a Solid Body,on the basis of which it is possible to make calculations of highly efficient elements of Photo-Thermo-Electronics.

Terrain Simplification Research in Augmented Scene Modeling

Augmented reality is the merging of synthetic sensory information into a user's perception of a real environment. As one of the most important tasks in augmented scene modeling, terrain simplification research has gained more and more attention. In this paper, we mainly focus on point selection problem in terrain simplification using triangulated irregular network. Based on the analysis and comparison of traditional importance measures for each input point, we put forward a new importance measure based on local entropy. The results demonstrate that the local entropy criterion has a better performance than any traditional methods. In addition, it can effectively conquer the 'short-sight' problem associated with the traditional methods.

Polynomial Entropy of Amenable Group Actions for Noncompact Sets

In this paper, we define and study polynomial entropy on an arbitrary subset and local measure theoretic polynomial entropy for any Borel probability measure on a compact metric space,and investigate the relation between local measure-theoretic polynomial entropy of Borel probability measures and polynomial entropy on an arbitrary subset. Also, we establish a variational principle for polynomial entropy on compact subsets in the context of amenable group actions.

In this paper, Brin-Katok local entropy formula and Katok＇s definition of the measuretheoretic entropy using spanning set are established for the random dynamical system over an invertible ergodic system.

Relative volume comparison of Ricci flow

In this paper we derive a relative volume comparison of Ricci flow under a certain local curvature condition.It is a refinement of Perelman’s no local collapsing theorem in Perelman(2002).
