Objective:
To know what are Web-safe colors, how to generate the RGB components for a given jpeg color image, or convert an image to RGB manually?
Main requirements:
Ability of programming with C, C++, or Matlab.
Instruction manual:
In order to complete this project, it is necessary that you find a program capable of generating the RGB component images for a given jpg color image. For example, MATLAB’s Image Processing Toolbox can do this, but you can also do it with image editing programs like Adobe’s Photo-Shop or Corel’s Photo-Paint. It is acceptable for the purposes of this project to convert an image to RGB (and back) manually.
(a) Write a computer program that converts an arbitrary RGB color image to a web-safe RGB image (see Fig. 6.10 for a definition of web-safe colors).
(b) Download the image in Fig. 6.8 and convert it to a web-safe RGB color image. Figure 6.8 is given in jpg format, so convert your result back to jpg (see comments at the beginning of this project). Explain the differences between your result and Fig. 6.8.

這次實驗是生成網頁安全色模板，內容較簡單，直接上代碼。

實驗代碼：

% close all; clc; clear all;% img = imread('Fig6.08.jpg'); figure; subplot(1,2,1); imshow(img); title('original image');% img1 = fix((img/51)*51); subplot(1,2,2); imshow(img1); title('web colors');

實驗結果：
