该资料使用时间差分、背景差、自适应背景更新等方法进行运动目标跟踪。

本文以一个简单实例讲述了C#实现自定义双击事件的方法，分享给大家供大家参考之用。具体方法如下： 主要功能代码如下： public partial class Form1 : Form,IMessageFilter { public Form1() { InitializeComponent(); Application.AddMessageFilter(this); } private int WM_LBUTTONDBLCLK = 0x0203; public bool PreFilterMessage(ref Message

This book is an introduction to computer graphics with an emphasis on applica- tions programming. The first edition, which was published in 1997, was somewhat revolutionary in using OpenGL and a top-down approach. Over the succeeding 16 years and 6 editions, this approach has been adopted by most introductory classes in computer graphics and by virtually all the competing textbooks. The sixth edition reflected the recent major changes in graphics software due to major changes in graphics hardware. In particular, the sixth edition was fully shaderbased, enabling readers to create applications that could fully exploit the capabilities of modern GPUs. We noted that these changes are also part of OpenGL ES 2.0, which is being used to develop applications for embedded systems and handheld devices, such as cell phones and tablets, and of WebGL, its JavaScript implementation. At the time, we did not anticipate the extraordinary interest in WebGL that began as soon as web browsers became available that support WebGL through HTML5. As we continued to write our books, teach our SIGGRAPH courses, and pursue other graphics-related activities, we became aware of the growing excitement about WebGL. WebGL applications were running everywhere, including on some of the latest smart phones, and even though WebGL lacks some of the advanced features of the latest versions of OpenGL, the ability to integrate it with HTML5 opened up a wealth of new application areas. As an added benefit, we found it much better suited than desktop OpenGL for teaching computer graphics. Consequently, we decided to do a seventh edition that uses WebGL exclusively. We believe that this edition is every bit as revolutionary as any of the previous editions.

针对高速医疗检测仪器对高灵敏和较强自适应能力的需求，提出一种基于PLL的自校准液面检测系统设计。该设计首先通过PLL电路将探针电容的变化转换为电压的变化，然后采用自校准算法调节PLL芯片VCIN的静态工作电压，最后结合自适应检测算法实现液面检测功能。实验表明，该液面检测系统中MCU输出的液面检测信号与检测电路产生的输出信号之间的延迟约为1.6 ms；同时能兼容样本针与试剂针液面检测系统，且所有探针的插入液面深度最大误差仅为0.37 mm，满足全自动生化分析仪的临床检验要求。

在本文中，我们考虑了为连续时间非线性系统开发控制器的问题，其中控制该系统的方程式未知。 利用这些测量结果，提出了两个新的在线方案，这些方案通过两个基于自适应动态编程（ADP）的新实现方案来合成控制器，而无需为系统构建或假设系统模型。 为了避免对系统的先验知识的需求，引入了预补偿器以构造增强系统。 通过自适应动态规划求解相应的Hamilton-Jacobi-Bellman（HJB）方程，该方程由最小二乘技术，神经网络逼近器和策略迭代（PI）算法组成。 我们方法的主要思想是通过最小二乘技术对状态，状态导数和输入信息进行采样以更新神经网络的权重。 更新过程是在PI框架中实现的。 本文提出了两种新的实现方案。 最后，给出了几个例子来说明我们的方案的有效性。 （C）2014 ISA。 由Elsevier Ltd.出版。保留所有权利。

要实现下图的效果（自定义多选单选），大多数公司项目的多选框都是自己设计的，所以用原生标签或者组件是不可行的，最简单的是自己绑定事件，然后切换选择和未选择的图片。而小程序和vue一样是没法操作dom的，所以要利用数组的下标和自定义属性来进行三元判断。 直接上代码： wxml： /**用wx:for来进行列表渲染**/ {{item.message}} /**利用数组的下标index来进行判

传统核窗宽固定的mean shift跟踪算法不能很好地对尺寸变化的目标进行有效的跟踪。在结合增量试探法和梯度方向检测的基础上，提出了一种适应带宽的mean shift目标跟踪算法。算法能够对逐渐放大和逐渐缩小的目标都能够进行有效的跟踪，解决了增量试探法难以很好地对放大目标进行自适应带宽跟踪的问题，提高了自适应带宽跟踪的准确性。两段不同场景下的运动目标跟踪实验，证实了该算法的有效性。

引入label信息的做法是，给判别器一个额外的one-hot向量作为输入，这个向量代表类别信息，另外，它还有额外的一个类别用来表示无标记的样本。比如，对于MNI
