Matlab GUI-based motion blur elimination (inverse filtering)

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