function varargout = dipfinalproject(varargin)
% DIPFINALPROJECT MATLAB code for dipfinalproject.fig
% DIPFINALPROJECT, by itself, creates a new DIPFINALPROJECT or raises the existing
% singleton*.
%
% H = DIPFINALPROJECT returns the handle to a new DIPFINALPROJECT or the handle to
% the existing singleton*.
%
% DIPFINALPROJECT('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DIPFINALPROJECT.M with the given input arguments.
%
% DIPFINALPROJECT('Property','Value',...) creates a new DIPFINALPROJECT or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before dipfinalproject_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to dipfinalproject_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Since you have not said the slightet amount of what is wrong with your code, I consulted the MATAB crystal ball. But there is some fog. I think it is saying that you may come into a large sum of money. Or maybe you will owe a lot of money. Blasted foggy crystal ball.
So if you want help, then explain what is the problem, as all we see is a large pile of not very easy to read code.

it gives me this error
Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)dipfinalproject('importimage_Callback',hObject,eventdata,guidata(hObject))

Change
a=uigetfile();
filename=a;
to
[a, filepath] = uigetfile();
if ~ischar(a); return; end %user cancel
filename = fullfile(filepath, a);
