糊涂先生给他的五个朋友写信,他写了五封信,但是当他的朋友收到信后,都告诉他:“你的信寄错了”。那么请你计算一下:出现这种情况的概率有多少?(假设糊涂先生是随机地往信封里装信的),你能不能把所有的情况都列出来呢?-confused to his five friends in a letter he wrote five letters, but when his friend received the letter, had told him : "You sent a letter wrong." Then you do some calculations : this happens the probability is the number? (Assuming confused is randomly installed to envelope the letter), you can put all the cases listed?

  • TPS变形、线性插值、最近邻插值
    应用背景线性插值、最近邻插值算法,自己写的代码,可以作为参考实现opencv里cvresize的功能,可以应用在图像变形后插值不成功的点,效果不错,根据实际情况选择算法。TPS变形算法应用于图像变形,矫正摄像机畸变。关键技术线性插值、最近邻插值算法,都是自己写的,可以作为参考实现opencv里cvresize的功能,TPS薄板样条函数变形算法应用于图像变形,真的蛮实用的,希望可以帮到你。TPS就是一种插值方法,它寻找一个通过所有的控制点的弯曲最小的光滑曲面;就像一个薄铁板,通过所给定的几个“样条”(比如木条),铁板表面是光滑的。

  • GeneralizedMIMO
    应用背景In this context, mobile communications may be allowed to be an indispensable commodity by most, and mobile data, video as well as television services are also becoming an essential part of everyday life. With the introduction of the Android operating system and the iPhone, the use of ebook readers such as the iPad, and the success of social networking using Facebook, the demand for cellular data traffic has grown significantly in recent years. Thus, communications on the move has proven to be transformational, and mobile operators struggle to satisfy the data traffic demands in wireless cellular networks,while keeping their costs at minimum to maintain profitability.关键技术The need for power-efficient MIMO-aided cellular networks requires a paradigm shift in the wireless system design. This trend is irreversible and will have a profound impact on both the theory and p
