各位大大好
小弟第一次寫matlab GUI
想要寫一個簡單的對灰度圖片做去背的小程式
現在卡在建立好的editor輸入值無法丟進去blkproc裡面
想要每次輸入的值不同取代固定的[16 16]
請問blkproc要如何使用呢?
--------------基本程式碼---------------------------------
I = imread('cameraman.tif');
bks = blkproc(I, [16 16], 'min(x(:))');
bg = imresize(bks, size(I), 'bilinear');
tm = imsubtract(I, bg);
figure;
subplot(1, 2, 1); imshow(I); title('原图像')
subplot(1, 2, 2); imshow(tm); title('去掉背景后的图像')
--------------------------------------------------------
-----------------------------GUI程式------------------------
function varargout = GUI(varargin)
% GUI MATLAB code for GUI.fig
% GUI, by itself, creates a new GUI or raises the existing
% singleton*.
%
% H = GUI returns the handle to a new GUI or the handle to
% the existing singleton*.
%
% GUI('CALLBACK',im,eventData,handles,...) calls the local
% function named CALLBACK in GUI.M with the given input arguments.
%
% GUI('Property','Value',...) creates a new GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before GUI_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to GUI_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

想要取代可是不知道如何表示
有大大可以給方向嗎?
