ippiConvValid_32f -9 mem error

[Ryan2]

Hi,

Assuming all images are sqaure for this example and all kernel sizes are odd.

I = input image size before padding

k = kernel size (always odd)

We pad I by k.

Src1 forippiConvValid is of size I + k - 1

Scr2 forippiConvValid is of size k

According to the documentation,

dest of ippiConvValid_32f is of size ( I + k -1 ) - k + 1 = I

Everything work perfect!!...until k > I

When k > I,ippiConvValid_32f outputs black.

Can someone please lookinto this for me. I need a solution to this problem as k is often greater than I.

Is there a workaround?

Thanks,

Ryan

but what is the return Value of ippiConvValid when k > i?

We installed IPP 7.0.7 The error is now solved!!!

We're able to convolve all the way up until we get a -9 memory error:

ippStsMemAllocErr

/* Memory allocated for the operation is not enough. */

Thanks!

Hi,

I'm testing on a Win7 64bit. Intel Xeon 24 thread machine with 32GB of RAM.

I'm getting: ippStsMemAllocErr = -9, /* Memory allocated for the operation is not enough. */ withippiConvValid_32f_C1R

When I increase the size of the kernel forippiConvValid_32f_C1R incrementally until I get the error -9. On input sizes just prior to the -9 error, my system is just barely using 6GB.

I am often doing large convoultion and need to be able to utilize my 32GB of system memory. Help please?

Best,

Ryan
