手写文字识别系统,可以实现图片直接转换成txt文档

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