Problem with ippiFilterLaplace_8u_C3R (PXA270)

hi_alex_lim — Sat, 16 Jun 2007 18:52:14 GMT

I used IPP in my smartphone for a fast image processing.

When I apply a ippiFilterLaplace_8u_C3R to my image buffer, the filter function
doesnot running completely. This means that, there is no change after running this filter
function which comes from IPP. In some case, program is halted immediately after running
filter function. (Size is correct. 240x320 image)

I used Visual Studio 2005, amd Windows Mobile 5 SDK.

The sample that I received from this forum works nicely on my smart phone. (C# wrapper)

But, when I reproduce that library using C/C++, it isn't.

Is anyone who can solve this problem?

The code sample isbelow

(Note that, pImageData is a BYTE* and has 320*240*3 bytes)

Ipp8u *ipprgb = NULL;
Ipp8u *ippResult = NULL;
IppiSize size;

size.width = 240;
size.height = 320;

ipprgb = ippsMalloc_8u(size.width*size.height*3);
ippResult = ippsMalloc_8u(size.width*size.height*3);

ippiCopy_8u_C3R(pImageData,size.width*3,ipprgb,size.width*3,size);

ippiFilterLaplace_8u_C3R(ipprgb,
size.width*3,
m_tImg.pImageData,
size.width*3,
size,
ippMskSize3x3
);

ippiCopy_8u_C3R(ippResult,size.width*3,pImageData,size.width*3,size);

Dear Customer,

As you may know that Intel PXA27x processor has been sold to Marvell last year and the part of Intel IPP for PXA27x engineer team have been transferred to Marvell*, please check the related news at: http://www.intel.com/pressroom/archive/releases/20060627corp.htm

That means Intel no longer produces any newer version of IPP for PXA products, if you'd like further assistance for particular this function for PXA27x platform, you may contact Marvell via http://support.marvell.com.

Hope it helps.
Thanks,
