ROI's and offsets in FloodFill


If I understand correctly, when I want to perform an processing function (like thresholding)in a particular rectangular area, I do something like this
_____________________________________

ROI.height = blobs[i].rect.height;


ROI.width = blobs[i].rect.width;


ROIoffset = (int) blobs[i].rect.y * width + (int) blobs[i].rect.x;



status = ippiThreshold_LTValGTVal_8u_C1R(imgIpp+ROIoffset, width, binIpp+ROIoffset, width, ROI, threshold, 0, threshold, 255);

does the IPP 4.0 for linux suitable for me?

1, i'm developing ipp applications on pxa255, i notice that the ipp 4.0 is suit for pxa255 with wireless mmx, how can i if it's right for pxa255 board?
2, after i installed ippwmmx40 ifor linux,when i compile pca samples, it told me that i need iwmmxt_le-gcc,where can i get it? I have installed intel c++ compiler 8.0 for linux, is that also be useful? and what is the arguments if i use intel c++ compiler 8.0?
thank you!

have problem in using the ipp samples

Submitted by kodaku on

I have problem in using the ipp samples in evc.I use Sitsang board and it seems that the examples is STANDARD SDK oriented,not for SITSANG SDK ,then what specific configuration there should be if I wanna use ipp on Sitsang board? when I compile the attached program,I met with such problems as follows:
Linking...
casestudyshell.obj : error LNK2019: unresolved external symbol ippsConv_16s referenced in function qmain
ARMV4IRel/Casestudy.exe : fatal error LNK1120: 1 unresolved externals

Use of ROI

Submitted by hrhfhgemt on

Hi,

I'am a new User at the IPP.

I will usethe ROI feature with some IPP functions, but I'am not sure if I understand the use of ROI in the right way.
I tryed a Histogram calculation inside the ippisample application in the following way:

Code:

AEC Example


First, sorry by my english.

I have been testing the AEC example. I want to probe the effect of loudspeaker gain management. I put int the Left channel empty and a voice inthe Right channel. I execute de example (with the option SIMULATE_ROOM)and obtain a wave very similar to the Right channel. Is this correct??? I Think no,

Thanks Le-Chuck

programming with G.723.1 in IPP





when i'm programming an encode program with IPP, which is used to make G.723.1 CODEC, i've got a problem. beg for answer!

hereit is: how to generate the original speech code into weighted speech which is an input item in function ippsOpenLoopPitchSearch_G723_16s() and function ippsHarmonicSearch_G723_16s() and some other functions?
