Insufficient memory issue on windows

[sivavenkatay]

I was successful in compiling the binary for windows (had to add export macros for the classes to generate the lib file).

But when I run the exe with a simple model, it runs until the convolution (and prints a convolution time) and then crashes with an error like this -

OpenCV Error: Insufficient memory (Failed to allocate 64244 bytes) in unknown fu
nction, file ......\src\opencv\modules\core\src\alloc.cpp, line 52

It fails with all images (small or large). Has anyone encountered this before?

[sivavenkatay]

It's crashing here (In DynamicProgram.cpp)-

Ix.resize(nscales, vector3DMat(ncomponents));
Iy.resize(nscales, vector3DMat(ncomponents));
Ik.resize(nscales, vector3DMat(ncomponents));
rootv.resize(nscales, vectorMat(ncomponents));
-----> rooti.resize(nscales, vectorMat(ncomponents));

And I have plenty of memory on my machine.

It consumes 2G memory on my win7 x64...
After I move the backtracking part into dp algorithm, it works. It consumes about 280M at most.

Could you provide the code?

[Answeror]

See my fork: Answeror@65001f6

[sivavenkatay]

@bnascimento I am running the example code that comes with the project.

@Answeror - will try your fork and let you know.

[bnascimento]

@sivavenkatay you running a 32 bit or 64 bit implementation?
32bit has a memory limit of 2GB

@Answeror will test your code then let you have some feedback..
anyway ty

@Answeror should your function be merged upstream ? If so, please make a pull request.
