Dear all:
I want to use [filename pathname]=uigetfiles('.jpg','get a
file') to load many images to my workspace in matlab, but I got around
30,000 images, it exceed the bound, the results returned were filename {0},
pathname {0}, so what other methods can be used to load huge number of the
images please? Thanks in advance!!

load huge number of images into workspace

I am wondering if loading so many files is going to eat up your RAM !
As I know, matlab tries to store a given vector in contiguous memory on the
RAM.
If file size and memory is not a problem then I can't think of a reason why
it shouldn't matlab work.
Maybe try freeing unused vectors.
Good luck.

Hi Shu,
You can try to switch on the MultiSelect Mode as follows:
[filename pathname]=uigetfile('.jpg','get a file','MultiSelect','on')
then you can select the files you need and the filename will be a cell array
containing all the files' names.
I wish this helps.

Are u processing those images sequentially? If yes, u might want to get the
images iteratively and clear memory after each process..
