说明：  可以定位和扫描一维条形码EAN-13，带有例子，成功率高. 简单(barcode dectect and decode)

绘制二维nurbs曲线，可以通过改变控制点或者权重从而改变图形的形状。(Draw a two-dimensional nurbs curve that changes the shape of a shape by changing the control point or weight.)

用于PDA的GPS源代码(for PDA GPS source code)

这是计算机图形学中的对二维图形进行基本几何变换的程序(This is a two-dimensional computer graphics in the graphics program of basic geometric transformations)

用于读取IGES文件(IGES files for reading)

加权中值滤波,用于图像增强,只用于超声图像,对超声图像去噪有很好的效果(Weighted median filter is used for image enhancement, only for ultrasonic image, has the very good effect on the ultrasonic image denoising)

将曲线轮廓中的B-样条曲线通过最小二分法转换成一组能保持曲线轮廓形状的小折线。这样，原有的字体轮廓数据就从用曲线轮廓表示转变为用多边形表示，即用一组点及其先后顺序来描述轮廓。(Profile to Polygon)

说明：  对有噪声的图像进行图像复原，通过迭代算法实现此功能(Image restoration for noisy images, this function is implemented by an iterative algorithm)

dish tracking techniques

一种基于轮廓的步态识别文献，思路清晰便于实现(Based on the outline of gait recognition literature, to facilitate the achievement of clear thinking)
