| 摘 要： | 基图像是图像正交变换中比较重要的概念，但目前的文献对基图像的解释不够清楚，对基图像的绘制也没有提及。以二维DCT为例对基图像的概念和意义进行了详细地阐述；分析、解释了基图像的绘制原理，提出了一种用Matlab绘制二维DCT基图像的简便方法，该方法也适用于绘制其他正交变换的基图像。

| Abstract: | Basal image is an important conception on orthogonal transform. However, the interpretation of basal image is not clear, and the method of drawing is not mentioned presently. This paper based on two dimensional Discrete Cosine Transform (DCT) expounds the conception and significance of basal image in detail; analyses and interprets the principle of basal image drawing; synchronously, introduces a simple and convenient way to draw two dimensional Discrete Cosine Transform (DCT) or other basal image by Matlab. |
