在BCB环境下介绍了如何使用Tchart,代码以图像直方图为例。-In the BCB environment describes how to use Tchart, code to the image histogram as an example.

该程序简单实现了打开一幅图像，并绘制其直方图的功能-Simple implementation of the program to open an image and draw the histogram function

实现数字图像基本的各种处理（直方图统计，几何变换，二值化），三大变换（傅里叶，沃尔什，离散余弦），各种复原方法-Basic all kinds of digital image processing (histogram statistics, geometry transformation, binarization), three transform (Fourier, Walsh, discrete cosine), all kinds of recovery methods
