代码说明:

  对Lena图先进行jpeg压缩,再对压缩后的图像分别进行小波软阈值去噪和非抽样硬阈值去噪,比较两种去噪方案,非抽样硬阈值有更好的效果。这是根据一篇外文文献来进行编程的,最后有图像对比结果。(According to the paper of OPTIMAL WAVELET THRESHOLDING FOR VARIOUS CODING SCHEMES ,I firstly compresse the Lena picture using the jpeg method ,then respectivly denoise it using the wavelet soft-thresholding method and the undecimated DWT hard-thresholding method.Comparing the two method ,we can find the undecimated DWT hard-thresholding have a better result.)

    说明:  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述,最简单模型称为针孔模型。 因为相机镜头透镜的存在,使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)
