【matlab编程代做】水平集模型的图像分割 可以作为参考使用学习([Do] matlab programming generation level set image segmentation model can be used as a reference study)

为感谢惠俊英老师的谆谆教诲，特为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，再对照轻松跑完六份作业（六路招式），即入“水声物理”之江湖！ BELLHOP与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对BELLHOP的原创，也感谢Orlando Camargo Rodríguez此份大道至简的入门秘籍。更感谢由Free Software凝聚起来的自由科学家社区。(Bellhop is a highly efficient ray tracing program, written in Fortran by Michael Porter as part of the Acoustic Toolbox (available at the website of the Ocean Acoustic Library). Bellhop is designed in order to perform two-dimensional acoustic ray tracing for a given sound speed profile c(z) or a given sound speed field c(r; z), in ocean waveguides with flat or variable absorbing boundaries. Output options include ray coordinates, travel time, amplitude, eigenrays, acoustic pressure or transmission loss (either coherent, incoherent or semi-coherent).)

说明：  差分粒子群算法是一种新的模仿鸟类群体行为的智能优化算法，现已成为进化算法的一个新的重要分支。在基本粒子群算法和改进粒子群算法原理的基础上，实现了粒子群算法在函数优化、图像压缩和基因聚类中的应用。(Differential particle swarm optimization (DPSO) is a new intelligent optimization algorithm which imitates the behavior of bird swarm. It has become a new important branch of evolutionary algorithm. Based on the basic particle swarm optimization (PSO) algorithm and the improved principle of PSO, the application of PSO in function optimization, image compression and gene clustering is realized.)
