how can I use the image region analyzer for multiple images?

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.

Thanks i will try it

[hussain abdelaziz]

i try it but how can i save the result of images region anaylzer in excel sheet it work but i need to save the results in excel sheet

[hussain abdelaziz]

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

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.
