Hi all,, I have SERIOUS problem with my Matlab. I m going to do classification by using SIFT featrues (vl_sift function from VLFEAT and LIBSVM library).
I have 2000 Images for training. But everytime I tried to extract the SIFT features from that 2000 images, I always get errors and matlab will force to be closed (Exit)..
And the wierd things is that, when I extract the SIFT features for 200 images, I didnt get any errors.
Then I tried to extract only for 500 images, but I still get that errors..
I had setup the mex by using
Would you like mex to locate installed compilers [y]/n? y
Select a compiler:
[1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2013a\sys\lcc
[2] Microsoft Visual C++ 2008 SP1 in C:\Program Files\Microsoft Visual Studio 9.0
[0] None
Compiler: 2
Before this problems appear, I was able to do feat extraction for 2000 images..
Here is the error mssgs:

MATLAB uses lazy memory allocation. That means that if your code accesses a memory area that it should not (e.g. by incrementing a pointer beyond an allocated array) you may or may not see a segmentation fault (and you will not always see it immediately). If you run your code on 200 images 1000 times in a loop - do you see the error after a variable number of iterations? If so, this may be the explanation.
