本文介绍了两种新的图像增强算法:一种是基于模糊嫡的图像滤波器，另一种是改进的模糊松弛迭代增强算法。前者将图像分为若十窗日，分别计算每个窗日关于不同模糊集的模糊嫡，根据最 小模糊嫡原则，确定该窗日中心灰度的大小，该方法充分利用了图像窗日中像素的区域信息。 (This paper introduces two new image enhancement algorithm: one is based on fuzzy entropy image filters, another improved fuzzy relaxation iterative enhancement algorithms. The former image into the ten windows day, the date of each window on different fuzzy sets fuzzy entropy, were calculated according to the minimum fuzzy entropy principle, determine the size of the window day center gray, full use of the Japan-China pixels of the image window region information.)

A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations. The use of cosine rather than sine functions is critical for compression, since it turns out (as described below) that fewer cosine functions are needed to approximate a typical signal, whereas for differential equations the cosines express a particular choice of boundary conditions.

小波去噪,利用小波系数在相邻尺度上的相关性关系,针对小波系数估计中硬阈值方法和软阈值方法的缺点, 通过对双重量收缩函数得到的阈值乘以一个合适系数进行修定的折衷方法,提出了一种新的小波域局部自适应去噪算法.实验结果表明,该方法既可以去除噪声,又可以较好地保留图像的高频细节特征.(Wavelet denoising using the wavelet coefficients in adjacent scales of the correlation relationship between the estimation of wavelet coefficients for the hard thresholding and soft thresholding shortcomings, through the contraction of the double weight of the threshold function has been multiplied by a suitable coefficient revised compromise, proposed a new wavelet-domain partially adaptive denoising algorithm. The experimental results show that the method can remove noise, also can be used to retain the details of the characteristics of high-frequency images.)
