DCT
- 原始影像離散餘弦轉換處理程式，含ForwardDCT與InverseDCT兩種方法。-Discrete cosine converting the original image processing program, including ForwardDCT with InverseDCT two ways.
ImageFreqCipher
- 一种频域加密算法，图像经过DCT变换得到DCT系数，然后对DCT系数进行加密。然后对加密的DCT系数进行DCT反变换图像数据。最后对其加密后的图像数据进行线性变换来调整图像数据的取值范围在[0，255]。最后得到加密图像-A frequency-domain encryption algorithm, the image obtained through the DCT transform DCT coefficients, and then encrypt the DCT coefficien
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.
