[Graph program] MagneticPendulum_zdfsthbs DL : 0: A few years ago, I got an article named "Experimente zum Chaos" [translated.: "Experiments on Chaos"] from the the German version of the Scientific American. The article dates back to 1994, and introduces among others a simulation showing the chaotic motion of a pendulum under the influence of gravity and three magnets. For some reason, this simulation fascinated me and so I wrote a program implementing it. The original program was coded quite some time ago, and since then I almost forgot about it. But because now I want a high resolution image of this fractal for my wall, I had to recode it. [Stupid reason isn t it? So what!] -A few years ago, I got an article named "Experimente zum Chaos" [translated.: "Experiments on Chaos"] from the the German version of the Scientific American.

[Graph program] 20104226553336 DL : 0: 1.加入控制器（在文件UPhysics2DControllers中），可实现浮力、风力、万有引力场、爆炸、阻尼等效果。其中的风力与爆炸效果是原C++版本中所没有的。大家还有什么新奇的想法可以联系我，为box2D Delphi加入更多的控制器，实现更多的物理效果。 2.添加了单元UPhysics2DPolygonTool，实现任意多边形的细分化（三角化）。可使box2D支持任意边数的多边形和凹多边形物体。目前这部分的demo还未完成，一位外国朋友正在制作。-1. Join the controller (in the file UPhysics2DControllers in), can achieve buoyancy, wind, gravity field, explosion, damping effect. One effect of the wind and the explosion of the original C++ version does not have. What new ideas you can contact me for box2D Delphi add more controllers to achieve more physical effects. 2. Add the unit UPhysics2DPolygonTool, the segmentation of an arbitrary polygon (triangulation). Can box2D support any number of edges of polygons and polygon objects. This is part of the current demo has not yet completed, a foreign friend is making.

[Graph program] WatershedSegmentation1 DL : 0: 分水岭分割对图像特征使用梯度下降法和沿区域边界分析弱点(weak points) 来将像素分类为区域。想像在一个有水流动的拓扑地形结构中，水在重力的引导下聚集到一个地势较低的盆地。随着水量的增加，水将流满整个盆地直到水流溢出到另一个盆地，这样就会将一些小盆地吞没形成大的盆地。使用局部的几何结构来形成区域(集水的盆地)，在图像领域中正如使用一些诸如曲率或梯度强度等特征中的局部极值来将像素连接成区域。这种技术不像其他区域分割，它几乎不需要用户定义门限，尤其适合对以不同的特征类型从不同的数据集融合而来的图像进行分割。分水岭技术在那些不仅仅产生单一图像分割的应用中也更加灵活，但是使用一个门限，或者交互式地在一个用户绘图界面的帮助下，从一个可以提取一个单一区域或区域集的a-priori 中的一个分割层级更合适。-Watershed segmentation classifies pixels into regions using gradient descent on image features and analysis of weak points along region boundaries. Imagine water raining onto a landscape topology and flowing with gravity to collect in low basins. The size of those basins will grow with increasing amounts of precipitation until they spill into one another, causing small basins to merge together into larger basins. Regions (catchment basins) are formed by using local geometric structure to associate points in the image domainwith local extrema in some fea-ture measurement such as curvature or gradient magnitude. This technique is less sensitive to user-defined thresholds than classic region-growing methods, and may be better suited for fusing different types of features from different data sets. The watersheds technique is also more flexible in that it does not produce a single image segmentation, but rather a hierarchy of segmentations from which a single region or set of regio
