PROGRAM DESCRIPTION: In this assignment, you will be processing user submitted images in C++. Specifically, you will be labelling and counting the number of objects in a given image. Each image consists of a number of pixels, and initially all pixels will have one of two labels, 0 and1. 0 is considered a background pixel while a 1 represents a pixel that is part of an object. Your system will apply, over two iterations, the same label to pixels that are connected to form objects, and then count the number of objects for a given image.

Specifically, you will be labelling and counting the number of objects in a given image. Each image consists of a number of pixels, and initially all pixels will have one of two labels, 0 and 1. 0 is considered a background pixel while a 1 represents a pixel that is part of an object. Your system will apply, over two iterations, the same label to pixels that are connected to form objects, and then count the number of objects for a given image. Additionally, sample input files will be found on the CSE machines at home/jeh0289/public/csce1030/sp19/hw4 You can cd into that directory and copy the input files from there. Every line will contain the comma delimited list of 0/1 pixel labels. Example Input Image .Label 0 indicates a background pixel 11 0 1 01 0 1 11 110 00 1 Label 1 indicates a pixel that is part of an object ?

Then, it checks for ‘1’ (root) It replaces the label of (1, 4) with ‘1’ PROGRAM REQUIREMIENTS You must organize your program into three files: * euidHW4func.h This file will contain the include directives for the necessary libraries, any type definitions, any structure definitions, and the list of function prototypes (i.e. function euidHW4main.cpp This file will contain the local include directive for the header file as well as * the main function for the program. *euidHW4func.cpp This file will contain the local include directive for the header file as well as all function definitions (except the main) used in the program. *Be sure to replace euid with your EUID Be sure to submit all three files when submitting your assignment. As with all homework programs in this course, your program’s output will initially display the department and course number, your name, your EUID, and your email address. This output should be performed through a function you declare and define. Define a structure (i.e. struct) to represent a relationship between two integer labels. It should store two integer labels, and a pointer to another relationship structure of the same type * . * You will need to declare and define a function to process the user specified file by Prompting the user for a file name. If the file does not exist, let the user know this and reprompt until a correct file name is submitted. .Reading from the file and comectly storing the 0’s and 1’s into the dynamic 2-dimensional array You will need to declare and define a function that takes in a dynamic, 2-dimensional array and its size, and outputs the int value of every slot in a grid format. You will need to declare and define a function to perform the first pass processing of the image stored in the dynamic, 2-dimensional aray. The function should examine each pixel and process it in the following way. . . If the current pixel is a 0, the it is a background pixel and should be ignored If the current pixel is a 1, the label of the pixels above and to the left of the current pixel should be checked There will be three possible cases . Case 1: If the top and left pixels are background pixels or do not exist, create a new, non zero, positive integer, unique label and assign it to the current pixel.] ” Case 2: If one of the top or left pixels is a background pixel or does not exist, and the other has a label, the current pixel will be assigned the same label as the labeled pixel. Case 3: If both the top and left pixels have different labels, assign the current pixel the smallest label and store that there is a relationship between the two labels in a relationship structure. Be sure to connect the new structure at the end of the chain of structures, as this will be used in the second pass. See the First Pass example, and note the 2 ->1 style relations on the right side of the grid. ” ” You will need to declare and define a function to perform the second pass processing of the image stored in the dynamic, 2-dimensional array. The function should examine each pixel and process it in the following way. . If the current pixel is a 0, then it is a background pixel and should be ignored Otherwise, the pixel’s label should be checked against the chain of relationships, and if a relationship exists between its label and another label, the smaller label should replace the current one. The chain may need to be checked multiple times to ensure the smallest label is applied to a pixel. *See the Second Pass example. You will need to declare and define a function to count and output the current number of unique labels in the dynamic, 2-dimensional array Inside your main function you will need to . . Declare and dynamically allocate the correct amount of space for an 8×8, two-dimensional, dynamic array of integers representing the image to be processed. Declare a relationship structure pointer to maintain the chain of discovered relationships. Process the input file using the appropriate function and store the data in the dynamic aray. Because the dimensions of the image cannot be stored globally, be sure you store them for later function calls. Output the current state of the two-dimensional, dynamic array using the appropriate function. *Perform the first pass processing on the two-dimensional, dynamic aray using the appropriate function Output the updated state of the two-dimensional, dynamic array using the appropriate functioin. Output the current number of labels objects in the two-dimensional, dynamic array using the appropriate function. *Perform the second pass processing on the two-dimensional, dynamic array using the appropriate function and the chain of relationships. Output the final state of the two-dimensional, dynamic array using the appropriate function. Output the final number of labels objects in the two-dimensional, dynamic aray using the appropriate function. You should not to create or use any globally defined variables, though your struct should be globally defined. * . Your code should be well documented in terms of comments. For example, good comments in general consist of a header (with your name, course section, date, and brief description), comments for each variable, and commented blocks of code. This means, that in addition to the program printing your information to the terminal, it will also appear in the code in the comments as well. * Your program will be graded based largely on whether it works correctly on the CSE machines (eg.. cse01, cse02, …, cse06), so you should make sure that your program compiles and runs on a CSE machine. This programming assignment is designed to help you practice your coding on a larger project with various pieces of functionality. While the coding should be primarily your sole work, any help you I SAMPLE OUTPUT: Here is a sample output to help you write and test your code.
