Question

Write a Matlab Program to perform recovery of original document from torn fragments using Image Mosaicing of binary Image Processing with two step approach. Initially identify the initial set of matching fragment pairs and resolve the ambiguity among these fragments by reconstructing in to a original document

Answer 1

Create Functions in Files Both scripts and functions allow you to reuse sequences of commands by storing them in program files. Scripts are the simplest type of program, since they store commands exactly as you wou them at the command line. Functions provide more flexibility, primarily because you can pass input values and return output values. For example, this function named fact computes the factori. number (n) and returns the result (f). function f fact (n) f prod(1:n); end This type of function must be defined within a file, not at the command line. Often, you store a function in its own file. In that case, the best practice is to use the same name for the function and t this example, fact.m), since MATLAB® associates the program with the file name. Save the file either in the current folder or in a folder on the MATLAB search path. You can call the function from the command line, using the same syntax rules that apply to functions installed with MATLAB. For instances, calculate the factorial of 5 y - fact(5) 120 Starting in R2016b, another option for storing functions is to include them at the end of a script file. For instance, create a file named mystats.m with a few commands and two functions, fact an The script calculates the permutation of (3,2)

Contents of Functions and Files The body of a function can include valid MATLAB expressions, control flow statements, comments, blank lines, and nested functions. Any variables that you create within a function are stored within a workspace specific to that function, which is separate from the base workspace. Program files can contain multiple functions. If the file contains only function definitions, the first function is the main function, and is the function that MATLAB associates with the file name. Functions that follow the main function or script code are called local functions. Local functions are only available within the file End Statements Functions end with either an end statement, the end of the file, or the definition line for a local function, whichever comes first. The end statement is required if. .Any function in the file contains a nested function (a function completely contained within its parent). . The function is a local function within a function file, and any local function in the file uses the end keyword The function is a local function within a script file. Although it is sometimes optional, use end for better code readability.
