- 一个基于matlab的图像处理小例子，有dct压缩还原效果对比及dct和fft的频谱,A small matlab example of image processing, and to restore the effect of compression dct comparison of the fft and dct and spectrum
FreqWatermark
- 一种基于DCT的扩频水印算法，本算法通过对水印信息进行扩频，在原始载体图像的DCT域内进行水印嵌入。-DCT-based spread spectrum watermarking algorithm, the algorithm is spreading through the watermark information in the original carrier image of the DCT domain for watermark embedding.

- 据扩频通信技术原理，利用m序列生成水印，通过扩频码与待检测载体图像的相关性设计了DCT域 的彩色图像水印算法-Abstract：An algorithm of colour image watermark in DCT domain based on spread spectrum communication was introduced
DCTAndIDCT
- 图像的DCT余弦变换（频谱变换），包括IDCT变换以及反变换。经过测试修改源代码中的笔误。包括理论。-Image DCT cosine transform (spectrum transform), comprising IDCT transform and inverse transform. Tested modify the source code of a clerical error. Including theoretical.
DCT
- 该代码是对图像进行DCT变换，并显示变换后的图像和频谱-The code is DCT transforms the image and displays the transformed image and spectrum
myDCT
- 用解析式定义或矩阵式定义自行编写进行二维DCT和离散沃尔什-哈达玛变换的函数。 在Matlab中对给定图像进行二维离散傅立叶变换，并显示其居中的频谱图，可用Matlab自带函数进行实验。 分别用Matlab自带的dct2()和idct2()对给定图像进行二维DCT变换，并以图像的形式显示其变换系数矩阵。 -And the preparation of two-dimensional DCT is defined analytically discrete Wals
