Discreat cosin transform for data transfermation in c Lamguage

用DCT变换和小波变换对全色光学图像和多光谱图像进行融合，生成同一图像。-Use DCT transform and wavelet transform of the panchromatic optical images and multi-spectral image fusion to generate the same image.

The discrete cosine transform (DCT) represents an image as a sum of sinusoids of varying magnitudes and frequencies and used in image compression applications.  -The discrete cosine transform (DCT) represents an image as a sum of sinusoids of var
