我附加了一個示例GUI代碼,該代碼具有兩個軸和兩個圖像,當我使用ginput選擇種子點時,我可以在任一軸上進行選擇,Is反正到ginput限制到特定的軸如何將ginput限制爲當前座標軸以選擇種子點
% --- Executes on button press in open.
function open_Callback(hObject, eventdata, handles)
% hObject handle to open (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
global img1;
global img2;
img1 = imread('peppers.png');
img2 = imread('rice.png');
axes(handles.axes1);
imshow(img1,[]);
axes(handles.axes2);
imshow(img2,[]);
% --- Executes on button press in seedpointSelect.
function seedpointSelect_Callback(hObject, eventdata, handles)
% hObject handle to seedpointSelect (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
global img1;
global img2;
global x;
global y;
axes(handles.axes1);
imshow(img1,[]);
[y,x] = ginput(handles.axes1);
y = round(y); x = round(x);
set(handles.xcord,'String',num2str(x));
set(handles.ycord,'String',num2str(y));
上限制ginput到一個特定的軸任何幫助,
