代码说明:

使用MATLAB绘制HSV色彩空间图HSV颜色空间是根据颜色的直观特性由A. R.史密斯在1978年年创建的一种颜色空间,也称六角锥体模型(Hexcone模型).RGB和CMY颜色模型都是面向硬件的,而HSV(色调饱和度值)颜色模型是面向用户的。这个模型中颜色的参数分别是:色调(H:hue),饱和度(S:saturation),亮度(V:value)。这是根据人观察色彩的生理特征而提出的颜色模型(人的视觉系统对亮度的敏感度要强于色彩值,这也是为什么计算机视觉中通常使用灰度即亮度图像来处理的原因之一)。色调H:用角度度量,取值范围为0°~360°,从红色开始按逆时针方向计算,红色为0°,绿色为120°,蓝色为240°。它们的补色是:黄色为60°,青色为180°,品红为300°;饱和度S:取值范围为0.0~1.0;亮度V:取值范围为0.0(黑色)~1.0(白色)。HSV模型的三维表示从RGB立方体演化而来。设想从RGB沿立方体对角线的白色顶点向黑色顶点观察,就可以看到立方体的六边形外形。六边形边界表示色彩,水平轴表示纯度,明度沿垂直轴测量。与加法减法混色的术语相比,使用色相,饱和度等概念描述色彩更自然直观。

  • Soft_Source_FDTD_dielectric
    ABC_FDTD_Die(T) Implements simulation of a Gaussian Pulse over T time steps. ABC are for free space. If boundaries are in the Dielectric medium then the ABC fail. Dielectric medium begin and end can be specified with the code(ABC_FDTD_Die (T) Implements simulation of a Gaussian Pulse over T time steps. ABC are for free space.

  • Spatial-channel-model-for-MIMO-3GPP
    Repeater communication is one promising candidate solution in future cellular networks because of its ability to increase throughput, data rate and coverage. It is also considered as one candidate technology feature in 3GPP/LTE-A. Traditionally repeaters have been active continuously and perform blind forwarding without knowing the signal. However the repeater in LTE Advanced is likely to include some advanced functionalities such as frequency selectivity, gain controllability, multi antenna ability, advanced antenna processing, optimum power control algorithm, etc.
