明图 meaning in English

mintou

We present an image - hiding cryptosystem based on vector quantization and wavelet transform . the key information of secret image is encrypted and then hidden into another image , which can be publicly accessed . in the paper , we compress the key image information using vector quantization , and apply wavelet transform method in compressing and noise - removing to improve the image quality
论文中，使用矢量量化的方法大大压缩了保密信息的数据量，并将图像的小波变换应用在图像的前期压缩和后期去噪声的过程中，提高了压缩比，增强了明图的伪装性，减少了运算时间，优化了解密图像的效果。
