本代码主要用于数字水印技术中的空间域中的最低有效位算法，用于数字产品中的版权保护问题。(This code is mainly used for the least significant bit algorithm for digital watermarking technology in the spatial domain for digital products copyright protection issues.)

Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called prefix-free codes , that is, the bit string representing some particular symbol is never a prefix of the bit string representing any other symbol). Huffman coding is such a widespread method for creating prefix codes that the term Huffman code is widely used as a synonym for prefix code even when such a code is not produced by Huffman s algorithm.

Matlab不仅具有强大的数值运算功能，也同样具有非常强大的二维和三维图形绘制功能，尤其擅长于将各种科学运算结果的可视化。计算的可视化可以将不直观的数据通过图形来表示，从而发现其中的内在关系。Matlab的图形命令格式简单，可以使用不同的线形，色彩、数据点标记和标注等来修饰(Graphic Design)
