if i have set Desktop as my work space and my images are stored in "My Pictures " so what i want is to search the image automatically from My pictures folder that is not my work space how do i get it please help me with it
See this code to recurse into subfolders and find image files:
% Start with a folder and get a list of all subfolders. % Finds and prints names of all PNG and TIF images in % that folder and all of its subfolders. clc; % Clear the command window. workspace; % Make sure the workspace panel is showing. format longg; format compact; fontSize = 20; % Define a starting folder. start_path = fullfile(matlabroot, '\toolbox\images\imdemos'); % Ask user to confirm or change. topLevelFolder = uigetdir(start_path); if topLevelFolder == 0 return; end % 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) break; end listOfFolderNames = [listOfFolderNames singleSubFolder]; end 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)]; 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); end else fprintf(' Folder %s has no image files in it.\n', thisFolder); end end
Of course if you're looking for one particular filename , then you can just break out of the loops once you've found it. Use strfind() or strcmpi() to check if the found filename matches the desired filename.
