Use adjusted with imcontrast tool image

I dont know how to use the image which is adjusted from imcontrast tool. I take my original photo(image1) and then i turn to gray and open the imcontrast tool.

I intend to crop the new adjusted image.How can i do it? I tried this but doesn't work

clear all;
clc;
imtool close all; 
getfile = uigetfile('*.jpg','Pick an image');
image1=imread(getfile);
image2=rgb2gray(image1);
h1 = figure;
imshow(image2);
h=imcontrast(h1)
f = sprintf('Begin by choosing the desired values for contrast  .\n Then select a ROI and double click to crop');

uiwait(warndlg(f));

[cropped, rect] = imcrop(h);
