Hi. Please help me to solve this problem. I have two input which is a and b. The question is, how can I display HOG values for both image ? I want to display the values at the textbox called 'Purata' and 'Purata2'. The code are as below :-

function HOG_Callback(hObject, eventdata, handles)
    
a = getimage(handles.axes2)
b = getimage(handles.axes4)
[featureVector1,hogVisualization1] = extractHOGFeatures(a);
[featureVector2,hogVisualization2] = extractHOGFeatures(b);
axes(handles.axes16)
imshow(a); 
hold on;
plot(hogVisualization1);
axes(handles.axes17)
imshow(b); 
hold on;
plot(hogVisualization2);
set(handles.purata,'String',2)
set(handles.purata2,'String',2)
