I have been using the image region analyzer app for one image at a time, but I have a series of images that need to be processed, if there were any solution to make all of images faster ? i have more than 10000 image !!

See the FAQ:

In the inside of the loop, put a call to your custom image analysis function and pass it the image.

your code not work for me that work for me but i need to save it as excel sheet
function result = batchmyimfcn(inDir, outDir)
%batchmyimfcn Batch process images using myimfcn
% RESULT = batchmyimfcn(INDIR, OUTDIR) processes each file in INDIR
% using the function myimfcn.
%
% The following fields from the output of myimfcn are written with their
% corresponding file format to the output directory OUTDIR:
%
% The following fields are returned in the table RESULT
% bw

% Auto-generated by imageBatchProcessor app on 24-Sep-2015
%----------------------------------------------------------
if(nargin<2)
outDir = '';
end
if(nargin<1)
inDir = 'E:\2حسين ماجستير صور\ge 128\دولفين 128\Series_003_TEST-1 K.V 80 ma140\binary';
end
includeSubdirectories = true;
% Fields to place in result
workSpaceFields = {
'bw'
};
% Fields to write out to files. Each entry contains the field name and the
% corresponding file format.
fileFieldsAndFormat = {
};
% All extensions that can be read by IMREAD
imreadFormats = imformats;
supportedExtensions = [imreadFormats.ext];
% Add dicom extensions
supportedExtensions{end+1} = 'dcm';
supportedExtensions{end+1} = 'ima';
supportedExtensions = strcat('.',supportedExtensions);
% Allow the 'no extension' specification of DICOM
supportedExtensions{end+1} = '';
% Create a image data store that can read all these files
imds = datastore(inDir,...
'IncludeSubfolders', includeSubdirectories,...
'Type','image',...
'FileExtensions',supportedExtensions);
imds.ReadFcn = @readSupportedImage;
% Initialize output (as struct array)

[path, filename,~] = fileparts(outImageFileWithExtension);
outImageFile = fullfile(path,filename);
try

oneResult = myimfcn(im);
% Accumulate

% Add the field name and required file format for this
% field to the template output file name
outImageFileWithExtension = [outImageFile,'_',fieldName, '.', fileFormat];
try
imwrite(imageData, outImageFileWithExtension);
catch IMWRITEFAIL

end
result = struct2table(result,'AsArray',true);
end
function img = readSupportedImage(imgFile)
% Image read function with DICOM support
if(isdicom(imgFile))

function createDirectory(dirname)

I don't use that built-in app on the tool ribbon so I don't know what kind of output it uses.. I write my own stuff using toolbox functions.
