Perataan Histogram Dengan MATLAB

Masih tentang pengolahan citra tugas kedua makin berat nih MATLAB!!!! liat aja belum pernah, udah disuruh bikin perataan histogram aduu…uh ribet dech jadi puyeng. Pertama- tama gw memulai mencari mentahan MATLAB, kebetulan gw dapet yang versi 7 dari temen (bajakan……sst!). Lalu diinstal klik next aja terus. ***10 menit kemudian***. ampe ketemu finish Udah beres kan lanjutkan dengan melihat- lihat help yang sudah disediakan (lagi-lagi bahasa inggris). Udah puyeng ga ngerti lalu gw ngebrowse cari tutorial indonesia buat matlab + bahan buat perataan histogram.

Nich sourcode perataan histogram khusus grayscale yang udah gw edit dan gw telaah 3 hari 3 malam lalu telah amat disederhanakan guna kemudahan saat ditanya dosen, gw menggunakan gui biar mantab :

LISTING Coba.m

function varargout = coba(varargin)

% COBA M-file for coba.fig

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

% singleton*.

%

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

% the existing singleton*.

%

% COBA(‘CALLBACK’,hObject,eventData,handles,…) calls the local

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

%

% COBA(‘Property’,'Value’,…) creates a new COBA or raises the

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

% applied to the GUI before coba_OpeningFunction gets called. An

% unrecognized property name or invalid value makes property application

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

%

% *See GUI Options on GUIDE’s Tools menu. Choose “GUI allows only one

% instance to run (singleton)”.

% Begin initialization code – DO NOT EDIT

gui_Singleton = 1;

gui_State = struct(‘gui_Name’, mfilename, …

‘gui_Singleton’, gui_Singleton, …

‘gui_OpeningFcn’, @coba_OpeningFcn, …

‘gui_OutputFcn’, @coba_OutputFcn, …

‘gui_LayoutFcn’, [] , …

‘gui_Callback’, []);

if nargin && ischar(varargin{1})

gui_State.gui_Callback = str2func(varargin{1});

end

if nargout

[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

else

gui_mainfcn(gui_State, varargin{:});

end

% End initialization code – DO NOT EDIT

% — Executes just before coba is made visible.

function coba_OpeningFcn(hObject, eventdata, handles, varargin)

% This function has no output args, see OutputFcn.

% hObject handle to figure

% eventdata reserved – to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% varargin command line arguments to coba (see VARARGIN)

% Choose default command line output for coba

handles.output = hObject;

% Update handles structure

guidata(hObject, handles);

% UIWAIT makes coba wait for user response (see UIRESUME)

% uiwait(handles.figure1);

% — Outputs from this function are returned to the command line.

function varargout = coba_OutputFcn(hObject, eventdata, handles)

% varargout cell array for returning output args (see VARARGOUT);

% hObject handle to figure

% eventdata reserved – to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure

varargout{1} = handles.output;

% — Executes during object creation, after setting all properties.

function text1_CreateFcn(hObject, eventdata, handles)

% hObject handle to text1 (see GCBO)

% eventdata reserved – to be defined in a future version of MATLAB

% handles empty – handles not created until after all CreateFcns called

% — Executes on button press in cari.

function cari_Callback(hObject, eventdata, handles)

% hObject handle to cari (see GCBO)

% eventdata reserved – to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

[a, path]=uigetfile(…

{‘*.bmp;*.jpg’,'File yg dpet dibuka (*.bmp,*.jpg)’;

},…

‘Browser’);

if ~isequal(a, 0)

handles.buka=imread(fullfile(path,a));

guidata(hObject,handles);

hold on;

axes(handles.axes1);

imshow(handles.buka);

hold on;

axes(handles.axes2);

imhist(handles.buka);

else

return;

end

set(handles.text1,’string’,a);

% — Executes on button press in proses.

function proses_Callback(hObject, eventdata, handles)

% hObject handle to proses (see GCBO)

% eventdata reserved – to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

handles.proses=histeq(handles.buka);

guidata(hObject,handles);

hold on;

axes(handles.axes3);

imshow(handles.proses);

hold on;

axes(handles.axes4);

imhist(handles.proses);

Ga usah pusing Inti program ini cuman di statement ini handles.proses=histeq(handles.buka); selesai mudah kan. O ya ini cuman coba.m nya doang desainnya ada di coba.fig sengaja gw ga lampirin abis gw ga tau caranya maklum pengguna blog baru.
