滚动文字问题 实现了显示文字滚动的例子-rolling text of the issue and achieve a rolling display text examples

3次样条插值的c++实现 主要针对图形应用而写，对函数已经给出详细的注释，只需要按照插值过程调用函数即可-3rd spline interpolation c achieve targeted at graphics applications written to function has been given detailed notes, only the need to process called interpolation function can be

用c语言设计的fir低通滤波器，经过调试，可以使用。包含几个函数，可以看清，注释比较多，方便看懂。

该算法建立了由最小二乘法,离散点曲率和离散点曲率变化和三项组成的目标函数并求出了最优控制点序列坐标,采用非线性优化方法对权因子序列进行了调整,确立了逼近误差的近似表示方法,并提出了包括上述方法的循环判断流程.-The algorithm was established by the least squares method, discrete points, the curvature and the curvature change and the three discrete points consisting of the objective function and find the optimal sequence of control point coordinates, using non-linear optimization method for sequence weights have been adjusted establishes the approximation error of the approximate representation, and proposed, including the cycle of the above methods to determine flow.

关于图像边缘检测及方块编码的程序，有源码，编译后能运行，方便学习，有一定参考价值。-on edge detection and box coding procedures, source code, compile after the operation, facilitate learning, a certain reference value.
