Menghitung Region Property Suatu Citra Yang di Akuisisi Dari Webcam

Didalam prorgam region property ini akan di cari property dari suatu citra. Property yang di cari adalah : luas, panjang, lebar dan rasio. Kita akan menggunakan citra yang di ambil dari webcam (baca : Menggunakan Webcam di Matlab Untuk Proses Akuisisi Citra Digital).

function varargout = RegionProperty(varargin)

% REGIONPROPERTY MATLAB code for RegionProperty.fig

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

%      singleton*.

%

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

%      the existing singleton*.

%

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

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

%

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

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

%      applied to the GUI before RegionProperty_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

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

%

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

%      instance to run (singleton)".
