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