i cant extract surf features from 120 folders when i use to detect surf features from the folders i shows and error undefiend function or variable here is my code..
function pushbutton3_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton3 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Start with a folder and get a list of all subfolders.
% Finds and prints names of all PNG, JPG, and TIF images in
% that folder and all of its subfolders.
% Similar to imageSet() function in the Computer Vision System Toolbox:
clc; % Clear the command window.
workspace; % Make sure the workspace panel is showing.
format long g;
format compact;
% Define a starting folder.
start_path = fullfile(matlabroot, '\toolbox\images\imdemos');
% Ask user to confirm or change.
topLevelFolder = uigetdir(start_path);
if topLevelFolder == 0
% Get list of all subfolders.
allSubFolders = genpath(topLevelFolder);
% Parse into a cell array.
remain = allSubFolders;
listOfFolderNames = {};
while true
[singleSubFolder, remain] = strtok(remain, ';');
if isempty(singleSubFolder)
listOfFolderNames = [listOfFolderNames singleSubFolder];
numberOfFolders = length(listOfFolderNames)
% Process all image files in those folders.
for k = 1 : numberOfFolders
% Get this folder and print it out.
thisFolder = listOfFolderNames{k};
fprintf('Processing folder %s\n', thisFolder);
% Get PNG files.
filePattern = sprintf('%s/*.png', thisFolder);
baseFileNames = dir(filePattern);
% Add on TIF files.
filePattern = sprintf('%s/*.tif', thisFolder);
baseFileNames = [baseFileNames; dir(filePattern)];
% Add on JPG files.
filePattern = sprintf('%s/*.jpg', thisFolder);
baseFileNames = [baseFileNames; dir(filePattern)];
numberOfImageFiles = length(baseFileNames);
% Now we have a list of all files in this folder.
if numberOfImageFiles >= 1
% Go through all those image files.
for f = 1 : numberOfImageFiles
fullFileName = fullfile(thisFolder, baseFileNames(f).name);
fprintf(' Processing image file %s\n', fullFileName);
fprintf(' Folder %s has no image files in it.\n', thisFolder);
