Part 1 : Image TraversalsĪs you learned in lecture, there are many ways to traverse a data structure. You will need to run make every time you change source code and want to compile it again. You will need to do the above once for each assignment. This directory has the files CMake needs to setup your assignment to be build.Īt this point you can in the build directory run make as described to build the various programs for the MP. which referes to the parent of the current directory which in this case is top of the assignment. This runs CMake to initialize the current directory which is the build directory you just made as the location to build the assignment. Now you need to actually run CMake as follows. This is not included in the provided code since we are following industry standard practices and you would normally exclude the build directory from any source control system. This is where you will actually build the assignment and then moves to that directory. This first makes a new directory in your assignment directory called build. Which in this assignment is the mp_traversals directory. To do this you need to run the following in the base directory of the assignment. This change does mean that for each assignment you need to use CMake to build your own custom makefiles. This allows for us to use libraries such as Catch2 that can be installed in your system rather than providing them with each assignment. This semester for MPs we are using CMake rather than just make. You will need to run these commands for every assignment that is released.Īll the files for this lab are in the mp_traversals directory. The second command will push to origin (your personal), which will allow it to track the new changes from release. Generally, these two flags shouldn’t be used, but are included for ease of merging assignments into your repo. The -no-edit flag automatically generates a commit message for you, and the -no-rebase flag will merge the upstream branch into the current branch. The first git command will fetch and merge changes from the main branch on your remote repository named release into your personal. git pull -no-edit -no-rebase release main -allow-unrelated-histories If you are using multiple machines you may need to use the following to allow them to work correcly. You can merge the assignments as they are released into your personal repo with git pull -no-edit -no-rebase release main You will need to have set up your git directory to have our release as a remote repo as described in our git set up The graphic suggests that in the current iteration, x = 4 and y = 3 both starting from 0.Īll assignments will be distributed via our release repo on github this semester. Figure below describes this Note that rows are being accessed one after the other. One way to traverse the image is in row first order. A) Intensity values shown in a grid of same dimension as image. In the figure below - Values in the grid represent the grayscale intensity of the image on the right. Of coordinates (x, y) is called the intensity value. Mathematically, an image can be considered as a function of two variables, f(x, y), where x and y are spatial coordinates and the value of the function at given pair You are welcome to get help on the MP from course staff, via open lab hours, or Piazza! Image and Image Traversal This MP, as well as all other MPs in CS 225, are to be completed without a partner.
