DIB（设备
DIB(Device-indepent bitmap)的与设备无关性主要体现在以下两个方面： DIB的颜色模式与设备无关。例如，一个256色的DIB即可以在真彩色显示模式下使用，也可以在16色模式下使用。 256色以下(包括256色)的DIB拥有自己的颜色表，像素的颜色独立于系统调色板。 由于DIB不依赖于具体设备，因此可以用来永久性地保存图象。DIB一般是以*.BMP文件的形式保存在磁盘中的，有时也会保存在*.DIB文件中。运行在不同输出设备下的应用程序可以通过DIB来交换图象。 DIB还可以用一种RLE算法来压缩图像数据，但一般来说DIB是不压缩的。 DIB的结构-DIB (Device-indepentent bitmap) has nothing to do with sexual equipment mainly in the following two aspects : DIB color mode has nothing to do with the equipment. For example, a 256-color DIB is the true color display mode, or can be used in 16 color mode. 256-color below (including 256 colors), the DIB has its own color table, color of the pixel independent system palette. As DIB is not dependent on specific equipment, it can be used for permanent preservation of images. DIB normally*. BMP file stored in the form of disk, sometimes stored in*. DIB document. Running on different output devices under the application of the procedure can be DIB to exchange images. DIB can also use a RLE compression algori

Cognitive radio frequency spectrum detection-The spectrum sensing of a wideband frequency range is studied by dividing it into multiple subbands.
It is assumed that in each subband either a primary user (PU) is active or absent in a additive white Gaussian
noise environment with an unknown variance. It is also assumed that at least a minimum given number of
subbands are vacant of PUs. In this multiple interrelated hypothesis testing problem, the noise variance is
estimated and a generalised likelihood ratio detector is proposed to identify possible spectrum holes at a
secondary user (SU). Provided that it is known that a specific PU can occupy a subset of subbands
simultaneously, a grouping algorithm which allows faster spectrum sensing is proposed. The collaboration of
multiple SUs can also be considered in order to enhance the detection performance. The collaborative
algorithms are compared in terms of the required exchange information among SUs in some collaboration

数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）水印嵌入过程为：数字水印（X）、原图像（I）和密钥/公钥（K）通过数字水印嵌入算法形成嵌入水印后的图像（I*）。 （2）水印检测过程为：数字水印（X）、水印图像（I*）和密钥/公钥（K）通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed!

动画正弦线
VB绘制正弦线，用VB实现在图片框中绘制坐标轴，并在坐标系内动态生成正弦线。注释：首先清除picture1内的图形，设置绘线宽度，绘坐标系的X轴及箭头线，绘坐标系的Y轴及箭头线，指定位置显示原点O，重设绘线宽度，用For循环绘点，使其按正弦规律变化。步长值很小，使其形成动画效果，指定位置显示描述文字
