我如何要求提供用戶輸入的matlab代碼？

Question

I = imread('image.jpg'); 
imshow(I); 
K = imadjust(I,[0.35 0.45],[]); 
figure 
imshow(K) 
imwrite(K,'image.jpg') 

我想彈出一個對話框讓用戶輸入[0.35 0.45]的值。如何修改提供的編碼以提示用戶輸入？

Answer 1

使用inputdlg：

I = imread('cameraman.tif'); 
imshow(I); 
% prompts for the two inputs 
prompt = {'Enter LOW contrast limit:','Enter HIGH contrast limit:'}; 
% title of the dialog box 
dlg_title = 'Input'; 
% number of input lines available for each variable 
num_lines = 1; 
% default answer for each input 
defaultans = {'0','1'}; 
% generate the dialog box and wait for answer 
answer = inputdlg(prompt,dlg_title,num_lines,defaultans); 
% convert string answers into doubles 
lo_in = str2double(answer{1}); 
hi_in = str2double(answer{2}); 
% apply on image 
K = imadjust(I,[lo_in hi_in],[]); 
figure 
imshow(K)
