Take home assessment to evaluate your understanding of object oriented concepts taught so far in IPRG001. The assessment will use your solution for Project A as a base. Project B will be composed of 3 parts: the updated scenario, the code and explanation (including proof of testing).
家庭作业评估，用于评估您对于IPRG001中到目前为止教授的面向对象概念的理解。该评估将以您对于A项目的解决方案为基础。B项目将由三个部分组成：更新的场景，代码和解释（包括测试证明）。
The scenario:
情境：
You will adapt your scenario from Project A to meet the requirements for project B. Perhaps it is a shop that sells class1 objects.
您将根据项目B的要求调整您从项目A中得出的场景。也许这是一家出售一类物品的商店。
Use class diagrams to document your class design.
使用类图来记录您的类设计。
The code:
这是一个代码：
Choose one of the thing classes(class1 or class2) and write a main class to store an array of objects.
选择一个事物类别（class1或class2），并编写一个主类来存储对象数组。
Write a menu() in the main class, to allows the user to view the contents of each object in the array, change the attribute value of one specific object, change the attribute value of all objects in the array.
在主类中编写一个 menu() 方法，允许用户查看数组中每个对象的内容，更改特定对象的属性值，以及更改数组中所有对象的属性值。
The explanation:
解释/说明
You will explain the code you wrote, at minimum you need to identify:
你将解释你编写的代码，至少需要识别以下内容:
Array size, name, objects held and indexes available.
数组大小、名称、包含的对象以及可用的索引。
For loops used, what conditions you chose and why.
使用for循环时，你选择了什么条件，以及为什么选择这些条件。
The menu code and explain what control structures are present in a menu and why they are needed.
菜单代码并解释菜单中存在哪些控制结构以及它们的必要性。
You also need to include at least 1 screen shot of your code being testing on the object bench.
您还需要至少包括一张代码在物体测试台上测试的截屏。
Please double check your code compiles and your submission document contains the updated version of all code prior to submission.
请务必确认您的代码可以编译，并且在提交之前，您的提交文档包含了所有更新版本的代码。
SUBMISSION
You will submit your assessment in MS Word document format – yourName-studNo.doc.
您将以 MS Word 文档格式提交您的评估报告 - 您的姓名-学号.doc。
The document will have 3 sections:
这份文件将分为3个部分：
The scenario: You will write the back story for your program – this will be assessed using LLO minimum 100 words
情景：您将为您的程序编写背景故事 - 这将使用LLO进行评估，最少100个单词。
The Code: You will copy the code from your BlueJ project into this section
代码：您将把BlueJ项目中的代码复制到此部分。
The explanation: you will explain your code choices and reasoning. You also need to include at least one screenshot of testing your code. Include any issues you had and how you resolved them. Minimum 300 words.
说明：您将解释您的代码选择和推理。您还需要包括至少一张测试您的代码的屏幕截图。包括您遇到的任何问题以及如何解决它们。最少300个单词。
在编写代码时，编程者通常需要做出许多决策，这些决策可能包括算法、数据结构、变量名等等。在此次项目中，我选择了一种用于检测图像中人脸的算法，这个算法名为人脸识别算法。我选择这个算法是因为它在识别人脸方面非常准确和可靠。
为了实现这个算法，我使用了Python编程语言和OpenCV库。我首先导入了OpenCV库，并将其用于读取图像文件和检测人脸。然后，我使用了一个名为Haar级联分类器的算法来检测图像中的人脸。这个算法通过识别人脸特征来确定人脸的位置，如眼睛、鼻子和嘴巴等。
在代码的实现过程中，我遇到了一些问题。例如，我发现有时候算法无法正确检测到图像中的人脸，特别是在图像中存在遮挡物或光线不足的情况下。为了解决这个问题，我尝试了几种不同的方法，包括增加训练数据、调整算法参数等。最终，我发现通过增加训练数据可以有效提高算法的准确性。
在测试我的代码时，我运行了几个图像文件，以确保它们能够正确地检测到人脸。我还创建了一个测试套件，其中包括了一系列不同的图像和场景，以测试算法的鲁棒性和准确性。在测试过程中，我发现我的代码在大多数情况下都能够正确检测到人脸，但在某些情况下可能会出现错误的检测结果。为了解决这个问题，我进一步调整了算法参数，并增加了一些特殊情况的处理逻辑。
总的来说，这个项目让我更深入地了解了人脸识别算法和OpenCV库，并提高了我的编程技能和解决问题的能力。我相信这个项目将对我的未来职业发展有所帮助。
Compress you BlueJ project and submit it and a zip file studentNo.zip as evidence of your work.
压缩您的BlueJ项目，并将其作为学号.zip文件一并提交，作为您的工作证据。
The deadline for this project is Friday 11:59pm, week 9.
