Description: 实验内容:
1.求下列3个模板的频率响应,并显示其三维图形;选择一幅图
像,利用这3个模板分别对该图像进行卷积运算,将卷积运算
获得的图像与原始图像进行比较,说明各模板的类型以及模板
(b)、(c)的区别与联系。
2. 选择一幅图像,对其进行离散Fourier变换,仅利用其相位谱重构原图像,然后仅利用其振幅谱重构原图像,比较实验结果;
选择两幅不同类型的图像,分别进行Fourier变换,交换二者的相位谱后求Fourier反变换,比较实验结果,说明图像Fourier相位谱的重要性。-Experimental contents: 1. Template for the following three frequency response and to show its three-dimensional graphics select an image using the three templates, respectively, of the image convolution operation, the convolution operation to obtain the images were compared with the original image to illustrate the template the type of template (b), (c) the difference with the contact. 2. Select an image, its discrete Fourier transform, only to use its phase spectrum remodeling the original image, and then only the use of its amplitude spectrum reconstruction of the original image to compare experimental results choice of two different types of images, respectively Fourier Transform, the exchange between the two after the phase spectrum for Fourier Transform, compare experimental results to illustrate the image of the importance of Fourier phase spectrum.

Description: This toolbox is meant to facilitate the manipulation of images and
video in Matlab. Its purpose is to complement, not replace, Matlab s Image
Processing Toolbox, and in fact it requires that the Matlab Image  Toolbox
be installed.    Emphasis has  been placed on code efficiency and
code reuse.-This toolbox is meant to facilitate the manipulation of images and
