PROJECT 03-01
Image Enhancement Using Intensity Transformations
The focus of this project is to experiment with intensity transformations to enhance an image. Download Fig. 3.8(a) and enhance it using
(a) The log transformation of Eq. (3.2-2).
(b) A power-law transformation of the form shown in Eq. (3.2-3).
In (a) the only free parameter is c, but in (b) there are two parameters, c and r for which values have to be selected. As in most enhancement tasks, experimentation is a must. The objective of this project is to obtain the best visual enhancement possible with the methods in (a) and (b). Once (according to your judgment) you have the best visual result for each transformation, explain the reasons for the major differences between them.
使用强度的转变实现图像增强
这个项目的焦点就是通过强度转换实验来增强图像。

下载图片3.8（a），并且对它实现增强。

对数变换的公式如3.2.2所示，幂次变换的基本形式如3.2.3所示。

在（a）中，唯一的自由参数是c，但是在（b）中有两个参数，c以及一个需要被选定值的参数r，在大多数关于增强的任务中，实验是必须的。

这个项目的目的是为了用在（a）和（b）中的方法来获得最佳可视化增强的可能性，一旦（根据你的判断）你对每一个变换都拥有了最好的视觉效果,解释一下它们之间产生主要差别的原因。

PROJECT 03-02 [Multiple Uses]
Histogram Equalization
(a) Write a computer program for computing the histogram of an image.
(b) Implement the histogram equalization technique discussed in Section 3.3.1.
(c) Download Fig. 3.8(a) and perform histogram equalization on it.
As a minimum, your report should include the original image, a plot of its histogram, a plot of the histogram-equalization transformation function, the enhanced image, and a plot of its histogram. Use this information to explain why the resulting image was enhanced as it was.
直方图均衡化
（a）写一个程序来计算图像的直方图
（b）实现直方图均衡化方法在参考3.3.1
（c）下载图38(a)并实现其直方图均衡。

你的实验报告中至少需要包括原图，绘制其直方图，增强后的图形，并绘制它的直方图。

用以上这些信息解释为什么图像的增强结果是这样的。

PROJECT 03-03 [Multiple Uses]
Arithmetic Operations
Write a computer program capable of performing the four arithmetic operations between two images. This project is generic, in the sense that it will be used in other projects to follow. (See comments on pages 112 and 116 regarding scaling). In addition to multiplying two images, your multiplication function must be able to handle multiplication of an image by a constant.
算术运算
编写计算机程序能完成两幅图像之间的四则算术运算。

这个项目是通用的,它将可用于其他项目。

(看112和116页关于缩放的备注)。

除了两张照片相乘,你的乘法函数必须能实现通过一个常数实现图像相乘。

PROJECT 03-04 [Multiple Uses]
Spatial Filtering
Write program to perform spatial filtering of an image (see Section 3.5 regarding implementation). You can fix the size of the spatial mask at 3 x 3, but the coefficients need to be variables that can be input into your program. This project is generic, in the sense that it will be used in other projects to follow.
空间滤波
编写程序执行图像的空间滤波(见第3.5关于实现)。

你能修大小为3×3的空间掩模,但是变量可以根据需要输入到你的程序。

这个项目是通用的,它将可用于其他项目。

PROJECT 03-05
Enhancement Using the Laplacian
(a) Use the programs developed in Projects 03-03 and 03-04 to implement the
Laplacian enhancement technique described in connection with Eq. (3.7-5). Use
the mask shown in Fig. 3.39(d).
(b) Duplicate the results in Fig. 3.40. You will need to download Fig. 3.40(a).
运用拉普拉斯增强（图像）
（a）程序开发项目03-03和03-04中使用的普拉斯增强技术和公式3.7-5有关
使用的掩模如图3.39（d）
(b)复制的结果,如图3.40。

你将需要下载图3.40(a)。

PROJECT 03-06
Unsharp Masking
(a) Use the programs developed in Projects 03-03 and 03-04 to Use the programs developed in Projects 03-03 and 03-04 to implement high-boost filtering, as given in Eq. (3.7-8). The averaging part of the process should be done using the mask in Fig. 3.34(a).
(b) Download Fig. 3.43(a) and enhance it using the program you developed in (a). Your
objective is to choose constant A so that your result visually approximates Fig. 3.43(d).
反锐化掩蔽。

（a）参考前面的03-03和03-04来实现高提升滤波处理，如公式3.7-8。

选用图片来完成这个功能。

（b）下载图片3.43（a），用你在（a）中开发的这个程序来对它实现增强，你的目的是选用一个常数A，这样你出来的结果在视觉上就很逼近图3.40（a）了。
