Introduction The usual implementation of malloc and free are unforgiving to errors in their callers' code, including cases where the programmer overflows an array, forgets to free memory, or frees a memory block twice. This often does not affect the program immediately, waiting until the corrupted memory is used later (in the case of overwrites) or gradually accumulating allocated but unused blocks. Thus, debugging can be extremely difficult. In this assignment, you will write a wrapper for the malloc package that will catch errors in the code that calls malloc and free. The skills you will have learned upon the completion of this exercise are pointer arithmetic and a greater understanding of the consequences of subtle memory mistakes. Logistics Unzip debugging_malloc.zip into an empty directory. The files contained are as follows: File(s): Function: debugmalloc.c Contains the implementation of the three functions you will be writing. This is the one file you will be editing and handing in. debugmalloc.h Contains the declaration of the functions, as well as the macros that will call them. driver.c Contains main procedure and the code that will be calling the functions in the malloc package dmhelper.c, dmhelper.h Contain the helper functions and macros that you will be calling from your code grader.pl Perl script that runs your code for the various test cases and gives you feedback based on your current code debugmalloc.dsp Exercise 3 project file debugmalloc.dsw Exercise 3 workspace file tailor.h, getopt.c, getopt.h Tools that are used only by the driver program for I/O purposes. You will not need to know what the code in these files do. Others Required by Visual C++. You do not need to understand their purpose Specification Programs that use this package will call the macros MALLOC and FREE. MALLOC and FREE are used exactly the same way as the malloc() and free() functions in the standard C malloc package. That is, the li

说明：一共有三个m文件，一个是lbp.m, 存放主要的lbp算法，一个是getmapping,用以做算法的辅助函数，一个是lbptest.m,存放着测试代码。这三个文件需要放到同一个文件夹，并在文件夹中添加相应的图片，具体的图片名字见lbptest.m的代码，运行lbptest.m可以查看结果。

此代码为彩色图像分割，matlab程序，利用Lab图像和Kmeans聚类算法进行分割，效果较好，程序可以运行，有对比。
