按黄师姐的推荐,小白回头查找起 FLUENT的资料来.通过网络及图书馆查找相关资料,小白对于FLUENT有了基本的认识. FLUENT是一个CFD软件包,目前隶属于ANSYS公司 目前FLUENT的最新版本为Fluent17.0,包括在ANSYS安装包内 FLUENT软件是ANSYS公司2005年收购于FLUENT公司,FLUENT公司开发的的最终版本为6.3,ANSYS收购后的第一个FLUENT版本为FLUENT12.0 FLUENT软件是市场占有率最高的通用CFD软件 FLUENT软件可以在…

结合这周看的论文,我对这周研究的Histogram of oriented gradients(HOG)谈谈自己的理解: HOG descriptors 是应用在计算机视觉和图像处理领域,用于目标检測的特征描写叙述器.这项技术是用来计算局部图像梯度的方向信息的统计值.这样的方法跟边缘方向直方图(edge orientation histograms).尺度不变特征变换(scale-invariant feature transform descriptors)以及形状上下文方法( shape c…
