二维离散余弦变换的图像压缩 直方图均匀化 数字图像矩阵数据的显示及其傅立叶变换 模拟图像受高斯白噪声和椒盐噪声的影响 (Two-dimensional discrete cosine transform image compression histogram equalization of digital image data matrix display and the analog image by the Fourier transform of Gaussian white noise and salt and pepper noise)

频域采样理论是数字信号处理中的重要理论。要求掌握模拟信号采样前后频谱的变化，以及如何选择采样频率才能使采样后的信号不丢失信息( Frequency range sampling )
