二、三维图像复原简介

三维图像的复原的流程如下所示：

根据以上流程，三维图像的复原可以分为以下几个部分：三维图像的获得，制作三维PSF，反卷积实现复原。下面分别说明。
1 三维图像的获得
将一幅图片进行微小角度的旋转，再叠加，以获得三维的图片。利用语句B=imrotate(A,angle,method,bbox)函数可以实现，其中，B表示旋转后的图片，A表示需要旋转的图片；angle表示旋转的角度；method参数可以改变插值算法，如’nearest’最邻近线性插值，’bilinear’双线性插值等；bbox参数用于指定输出图像属性：‘crop’： 通过对旋转后的图像B进行裁剪， 保持旋转后输出图像B的尺寸和输入图像A的尺寸一样；{‘loose’}：使输出图像足够大，以保证源图像旋转后超出图像尺寸范围的像素值没有丢失。
2 制作三维PSF
在已知显微镜的放大倍数M、数值孔径NA、照射光波长λ和光学管腔di的情况下，利用以下公式：



可以制作出三维的OTF，再利用otf2psf函数，即可得PSF。
3 反卷积实现复原
反卷积，即对模糊的图像进行去模糊，从而实现图像的复原。作业中采用的是最大似然法来处理，即

其中，h表示点扩散函数，g表示需要复原的模糊图像，表示对原始图像的估计。

三、部分源代码

function varargout = text(varargin)
% TEXT M-file for text.fig
%      TEXT, by itself, creates a new TEXT or raises the existing
%      singleton*.
%
%      H = TEXT returns the handle to a new TEXT or the handle to
%      the existing singleton*.
%
%      TEXT('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TEXT.M with the given input arguments.
%
%      TEXT('Property','Value',...) creates a new TEXT or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before text_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to text_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
