Dear all,
I have a problem in saving quadtree image from gui axes.
I've written this code to calculate quadtree decomposition
qt = qtdecomp(im,t);blocks = repmat(uint8(0),size(qt));for dim = [512 256 128 64 32 16 8 4 2 1]; numblocks = length(find(qt==dim)); if (numblocks > 0) values = repmat(uint8(1),[dim dim numblocks]); values(2:dim,2:dim,:) = 0; blocks = qtsetblk(blocks,qt,dim,values); endendblocks(end,1:end) = 1;blocks(1:end,end) = 1;hold on;axes(handles.quadtree); % axes for displaying quadtree image in gui Matlab
imshow(blocks,[]);
Then, i wanna save the image by calling this function
function save_Callback(hObject, eventdata, handles)% hObject handle to simpan (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
ImQuadtree = getimage(handles.quadtree);% getting image from quadtree axes
[nm_file,nm_dir] = uiputfile({'*.jpg';'*.bmp';'*.png';'*.tif';'*.*'},'Saving Quadtree Image');if isequal(nm_file,[]) msgbox('The Image is not Stored!','Warning','warn');elseif isequal(ImQuadtree,[]) msgbox('There is no image to stored!','Warning','warn');else imwrite(ImQuadtree,strcat(nm_dir,nm_file)); msgbox('Quadtree Image Successfully Stored','Save','help');end
The problem is when the image is successfully saved, the image result is a black image. There is no block on these image. So, how i can save the image block??
