session1 【Objective and Requirement】 Objective: Be familiar with the creation of process and thread on Windows. Requirement: Sub Task 1: Create a console application, "child", which keeps printing out "The child is talking at [system time]" (in a loop, one per 1s). Sub Task 2: Create another console application, "parent". It create a child process to execute “child”. The "parent" process keeps printing out "The parent is talking at [system time]". (one per 1s) Execute "parent" and explain the output you see. Sub Task 3: Create a "winPS" program which can output information about all the running processes. Try to output details about each process, such as PID, executable file name and path, etc. Sub Task 4: In the "mainThread" program, use "CreateThread" to create a child thread. Both the main thread and the child thread keep printing out "[ThreadID] + [System time]". session2 Objective: Create "ps" and "kill" commands on Windows. Requirement: Sub Task 1: On Linux/Unix there are a "ps" command and a "kill" command. The "ps" command can list information about all the running processes. The "kill" command can terminate processes. Based on the tasks finished in Session 1, create "ps" and "kill" commands on Windows. Tips: using "TerminateProcess" to "kill" a process. session3 Objective: Learn how to use semaphore to solve IPC problems. Requirement: Task 3.1. Sleeping barber Use semaphores to solve the problem of sleeping barber. Task 3.2. Reader & Writer Use semaphores to solve the reader and writer problem, with the readers (and writers) have higher priority. session4 Title: Upgrade Linux/Unix commands Problem: Write a program "supershell" that takes another command as an argument and executes that command. For instance, executing: “./supershell cat /usr/greg/readme" would invoke the cat command on the file /usr/greg/readme. After execution of the specified command has completed, "supershell" should display statistics that show some of the system resources the co

基于matlab的指纹识别系统源码 手指静脉识别项目 本项目详细介绍请参阅:图像处理创新实践.pdf 本项目开源许可协议:GPL 3.0(除SIFT算法软件包,此部分软件包另有原作者的许可协议) 项目方案设计介绍 本项目实现手指图像的处理和匹配算法,需要处理的数据是本人不同手指的图像,首先经过图像处理,使得指静脉的纹理增强凸显处理,然后将所有的这些图像进行相互间的匹配,检验类内和类间的匹配度,观察其是否能够明显区分开来,并据此计算正确率。 在本项目中,由于是基于算法原型的研究,因此我们选用了操作便捷的Matlab R2019b软件作为运行环境,在Windows 10 Pro for Workstation操作系统中实现算法。 算法分为以下几个过程: 图像预处理过程中,需要增强图像,提取手指区域,为识别做准备。拟采用CLAHE、直方图均衡、二值化等算法,以达到增强图像的效果;拟采用边缘检测算法实现手指的识别和提取 图像的特征提取和匹配过程中,拟采用两类不同的方法。一是局部不变特征提取算法。这些算法具有检测图像中的特征点,并对特征点的局部区域进行描述和匹配的功能。二是针对二值化图像的模板匹

Compiler Construction Experiment 1 Implementing a Scanner for TINY+ You are to write a lexical analyzer/scanner for the language TINY+. Goals 1The input of the scanner is a source code file and the output of the scanner is a stream of tokens. 2Your scanner should go for longest possible match i.e. a string ‘:=’ is to be identified as ‘ass-symbol’ rather than ‘:’ and ‘=’. 3Token is represented as (Kind, Value). We use the following symbols to denote different kinds of tokens KEY denotes reserved words SYM denotes special symbols ID denotes identifiers NUM denotes numeric constants STR denotes string constants 4Check lexical errors: giving meaning error messages and the lines where errors occur. The kinds of lexical errors are: Illegal character, that is, scanner may recognize a character that is not in the alphabet of TINY+, such as $ is an illegal character The right bracket of a STRING is lost, such as ' scanner The right delimiter of a comment is lost, such as: {this is an example Requirements 1Write your program in C or C++ 2This experiment must be finished in 4 periods. You will submit a report and the source code Example output for some TINY+ programs Test1 or and int bool char while do if then else end repeat until read write , ; := + - * / ( ) = a2c 123 'EFG' The scanner should give the outputs: (KEY, or) (KEY, and) (KEY, int) (KEY, bool) (KEY, char) (KEY, while) (KEY, do) (KEY, if) (KEY, then) (KEY, else) (KEY, end) (KEY, repeat) (KEY, until) (KEY, read) (KEY, write) (SYM, ,) (SYM, ;) (SYM, :=) (SYM, +) (SYM, -) (SYM, *) (SYM, /) (SYM, ( ) (SYM, )) (SYM, ) (SYM, =) (ID, a2c) (NUM, 123) (STR, EFG) Test2 {this is an example} int A,B; bool C1, C2, C3; char D; D:= 'scanner'; while A<=B do A:=A*2 end The scanner should give the outputs: (KEY, int) (ID, A) (SYM, ,) (ID, B) (SYM, ;) (KEY, bool) (ID, C1) (SYM, ,) (ID, C2) (SYM, ,) (ID, C3

华南理工大学的课程设计题目,相应的论文和代码,写得巨详细,保证拿优秀。因为在答辩的时候受到老师刺激,自己写的写得那么努力,结果老师拼命打断。而别人直接在网上 copy 的,呵呵,居然还优了,可以可以。因此我把他上传到网上,大家可以看看我写得怎么样,尽管拿去抄,没有积分的关注我,私聊我会在3天之内发给你。
