jpeg图像编/解码

用虚拟现实语言VRML编写的一个导弹模型以及飞行的虚拟场景！-using VRML preparation of a missile flight model and the virtual scene!

此原码包含两部分：标识物体测量面积和周长，阈值分割和轮廓提取。-This source code contains two parts: marking objects measuring the area and perimeter, threshold segmentation and contour extraction.

基于qt使用qzxing库，结合opencv，进行二维码和条形码的解码，视频显示和解码的过程在不同的进程，因此可以流畅的显示，在解码的同时。

一个人脸检测与识别系统实现的具体方法步骤，值得研究-A face detection and recognition system to achieve the specific method steps to be studied

显示图像3d灰度的一段代码-Gray 3d image shows a section of code

自己写的用DeCasteljau算法实现的Bezier曲面。-Using the Decastljau arithmetic to realize the Bezier surface

可以用来调整图像对比度和亮度的代码，用vc实现，不错的阿-images can be used to adjust contrast and brightness of code, using vc achieved good A

维纳滤波对图像去噪与最小二乘方滤波对图像去噪的比较-Wiener filter for image denoising with the least squares filter for image denoising comparison

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
