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