代码描述

中文说明:DCT变换域中,用一个公式来进行图像的质量增强。就是在保持图像灰度不变的情况下,将能量更多的转移到高频上去,看上去就会显得比较清晰的说。为了在渐进传输过程中快速对压缩图像进行增强,DCT域图像增强技术就变的非常迫切。DCT域图像增强技术可以消除逆变换到空域和正变换回DCT域的计算开销。 


English Description:

DCT transform domain, using a formula for enhanced image quality. Is that in the case of keeping the same image, to shift more of the energy to high-frequency sound, looks more clearly stated. To fast for compression in the transmission process to enhance the images, DCT-domain image enhancement technology, it has become very urgent. DCT-domain image enhancement technique can eliminate the inverse transform to space and transform back into the computation of the DCT domain.
