restore
说明: 图像增强的目标是改进图片的质量,例如增加对比度,去掉模糊和噪声,修正几何畸变等;图像复原是在假定已知模糊或噪声的模型时,试图估计原图像的一种技术。
图像增强按所用方法可分成频率域法和空间域法。前者把图像看成一种二维信号,对其进行基于二维傅里叶变换的信号增强。采用低通滤波(即只让低频信号通过)法,可去掉图中的噪声;采用高通滤波法,则可增强边缘等高频信号,使模糊的图片变得清晰。具有代表性的空间域算法有局部求平均值法和中值滤波(取局部邻域中的中间像素值)法等,它们可用于去除或减弱噪声。
(A sharp and clear image is not directly produced
from the optics, however, digital signal processing applied to the sampled image produces a sharp and clear final image that
is also insensitive to misfocus related aberrations. This paper gives an overview of Wavefront Coding and example images
related to the two applications of machine vision/label reading and biometric imaging. Design techniques of Wavefront
Coding are unique from that of traditional imaging system design since both the optics and digital processing characteristics
of the system are jointly optimized for optimum system performance.)

JPEGCompression
说明: 编码:
(1)进行颜色转换,将RGB格式转换为YUV格式。
(2)将待编码的N×N的图像分解成(N/8)^ 2 个大小为8×8的子图像。
(3)对每个子图像进行DCT变换,得到各子图像的变换系数。这一步的实质是把空间域表示的图像转换成频率域表示的图像。
(4)对变换系数进行量化。
(5)进行Z字形重排
(6)使用霍夫曼变长变码编码器对量化的系数进行编码,得到压缩后的图像(数据)。
解码:
(1) 对压缩的图像数据进行解码,得到用量化系数表示的图像数据。
(2) 进行反Z字型重排
(3)用与编码时相同的量化函数或量化值表对用量化系数表示的图像数据进行逆量化,得到每个子图像的变换系数。
(4)对逆量化得到的每个子图像的变换系数进行反向正交变换(如反向DCT变换等),得到(N/8)^2 个大小为8×8的子图像。
(5)将(N/8)^2 个大小为8×8的子图像重构成一个N×N的图像。
(6)进行颜色组合,将YUV格式转换为RGB格式图像。(JPEG compression and decompression process)

基于马尔科夫随机场的,例子学习超分辨率复原代码。(This is an implementation of the example-based super-resolution algorithm. Although the applications of MSFs have now extended beyond example-based super resolution and texture synthesis, it is still of great value to revisit this problem, especially to share the source code and examplar images with the research community. We hope that this software package can help to understand Markov random fields for low-level vision, and to create benchmark for super-resolution algorithms.)
