I need help with MATLAB programming. I am working on a image tampering project that checks for tampered images. I am currently using two cameras for my project that is the Cannon or Nikon. In my M file, it shows what camera I am running, and the picture that is pristine. It then checks for any tampering and shows the results. I have a GUI, and I want it to work by having the user select the camera type, and photo, and have it send the information over to the m file. The project folder already has set folder of images made. How is this possible? PLEASE HELP ME.

MATLAB GUIDE GUI:

function varargout = gui(varargin)

% GUI MATLAB code for gui.fig

% GUI, by itself, creates a new GUI or raises the existing

% singleton*.

%

% H = GUI returns the handle to a new GUI or the handle to

% the existing singleton*.

%

% GUI('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in GUI.M with the given input arguments.

%

% GUI('Property','Value',...) creates a new GUI or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before gui_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to gui_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".
