如何重置当前轴以在MATLAB中显示同一轴上的彩色图像或灰度图像？

Question

我有一些灰度图像，经过一些细分处理后，我将部分转换为彩色以用于显示目的。 但在同一轴上显示灰度图像后，我无法在轴上显示彩色图像。

例：

function pushbutton1_Callback(hObject, eventdata, handles) 
% hObject handle to pushbutton1 (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 
global imB 
global imF 
global finalSegment_LE 
i=38; 
%   imB = img2{i} ;% Background original image 
tempSeg = finalSegment_LE{i}; 
tempSeg(finalSegment_LE{i} ==0) = min(finalSegment_LE{i}(:)); 
imF = tempSeg; 
cla(handles.axes1,'reset'); 
[~,~] = imoverlay(imB,imF,[],[],'hsv',0.8,handles.axes1); % color image.. 


% --- Executes on button press in pushbutton2. 
function pushbutton2_Callback(hObject, eventdata, handles) 
% hObject handle to pushbutton2 (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 
% global imB 
temp = imread('cameraman.tif'); 
cla(handles.axes1,'reset'); 
axes(handles.axes1); 
imshow(temp,[]) % grayscale image... 

如果我按pushbutton1首先我看到彩色图像，但我按pushbutton2后，轴变为灰度，甚至当我按下pushbutton1，它仍然显示灰度图像，而不是彩色图像。

谢谢，
