The paper applies the thoughts of partial differential equations  puts forward a new improved method of image enhancement. This method can enhance not only the dark images but also the bright images  making the details hidden in the dark background and the bright background very clear. The application scope is wider  and the visual effect is better. This paper uses the finite difference method to discrete the partial differential equations  and combines with the heat equation. It calculates simple  runs fast  and provides a guarantee for real-time video image enhancement processing. 2010 IEEE.   Lie symmetries of soliton equations with self-consistent sources via source generation procedure 期刊论文  OAI收割 JOURNAL OF MATHEMATICAL ANALYSIS AND APPLICATIONS, 2009, 卷号: 357, 期号: 1, 页码: 201-213 作者:  Hu, Juan;  Qian, Xian-Min;  Tam, Hon-Wah   |  收藏  |  浏览/下载：24/0  |  提交时间：2018/07/30 KP equation  Sawada-Kotera (SK) equation  Differential-difference KP equation  Lie symmetries  Self-consistent sources  Source generation procedure   Integrability of a differential-difference KP equation with self-consistent sources 期刊论文  OAI收割 MATHEMATICS AND COMPUTERS IN SIMULATION, 2007, 卷号: 74, 期号: 2-3, 页码: 145-158 作者:  Gegenhasi;  Hu, Xing-Biao   |  收藏  |  浏览/下载：26/0  |  提交时间：2018/07/30 solitons  Backlund transformation  Lax pair  differential-difference KP equation with sources   A hierarchy of nonlinear differential-difference equations and a new Bargmann type integrable system 期刊论文  OAI收割 PHYSICS LETTERS A, 2006, 卷号: 359, 期号: 1, 页码: 47-51 作者:  Sun, Ye-Peng;  Chen, Deng-Yuan;  Xu, Xi-Xiang   |  收藏  |  浏览/下载：35/0  |  提交时间：2018/07/30 differential-difference equation  Hamiltonian structure  binary nonlinearization  Liouville integrability   Matrix integrals and several integrable differential-difference systems 期刊论文  OAI收割 JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN, 2006, 卷号: 75, 期号: 5, 页码: 5 作者:  Hu, Xing-Biao;  Zhao, Jun-Xiao;  Li, Chun-Xia   |  收藏  |  浏览/下载：23/0  |  提交时间：2018/07/30 matrix integrals  Pfaffian  Casorati determinant  two-dimensional Toda lattice  differential-difference KP equation  semi-discrete Toda lattice   New explicit rational solitary wave solutions for discretized mKdV lattice equation 期刊论文  OAI收割 COMMUNICATIONS IN THEORETICAL PHYSICS, 2005, 卷号: 44, 期号: 6, 页码: 1011-1014 作者:  Yu, YX;  Wang, Q;  Zhang, HQ   |  收藏  |  浏览/下载：23/0  |  提交时间：2018/07/30 differential-difference equations  discretized mKdV lattice equation  solitary wave solution  rational expand method   An approach to directly construct exact solutions of nonlinear differential-difference equations 期刊论文  OAI收割 NONLINEAR ANALYSIS-THEORY METHODS & APPLICATIONS, 2005, 卷号: 62, 期号: 8, 页码: 1490-1497 作者:  Xie, FD;  Wang, DK;  Lu, ZS   |  收藏  |  浏览/下载：26/0  |  提交时间：2018/07/30 differential-difference equation  travelling wave solution  symbolic computation
