代码说明:

应用背景自适应地切割图像局部区域,该局部区域的特征是纹理变化比较大,也就是纹理特征的熵比较大,这种情况下代表的图像特征也就比较明显。这个区域的特征点数量多而且稳定,适用于图像匹配、图像拼接等领域。关键技术借用opencv图像处理库函数,实现图像的轮廓提取,形态学运算,图形块分割,先将小于设定的面积阈值的图像块删除,在通过纹理熵比较获得纹理变化最大的图像块。

  • ISM编程实现
    本算法有别于传统的ISM模型求解,运用邻接表和图论遍历的相关知识,运用C++编程实现。运用结构体表示要素的信息,运用链表表示要素之间的关系,通过遍历划分区域,提出级位划分的一种新方法,是很值得学习和借鉴的。代码均原创,若有什么问题,也欢迎大家反馈!

    详细表述了分数阶傅立叶变换的离散实现,将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that lters the best out of the existing ones. Two types of transforms are considered: First the fast approximate fractional Fourier transform algorithm for which two algorithms are available. The method is described in H.M. Ozaktas, M.A. Kutay, and G. Bozdagi. Digital computation of the fractional Fourier transform. IEEE Trans. Signal Process., 44:2141{2150, 1996. There are two implementations: one is written by A.M. Kutay the other is part of package written by J. O Neill. Secondly the discrete fractional Fourier transform algorithm described in the master thesis C . Candan. The discrete fractional Fourier transform, Bilkent Univ., 1998 and an algorithm described by S.C. Pei, M.H. Yeh, and C.C Tseng: Digital fractional Fourier transform base

  • 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
