hello,
i recieved ur mail. The labview software for which u r requesting is of 542MB(zip file size) + driver software(94MB) and such large file i can't send u as an attachment via mail or through EDABOARD forum.
So i suggest u to download software for labview8.2 directly from national instruments website. Enter "free download of Labview8.2 software in yahoo search and u will get link for national instrument website for labview software download.Become its member(free) and then download software.
Use broadband connection to download software.I suggest u better download software via Internet Download Manager.So if downloading is interuppted at some point,u can resume from that point only.

have a nice day!

by name model based design .it's also on the matlab webpage under webinars

The following Sobel filter for edge detection gives u the idea of detecting the edges


////////// To Dectect Edge using Sobel Filter //////////
w=width;
for( i=0;i<height;i++)
{
for( j=0;j<3*width
{
pcSrcBuffer[k-w]=(pcSrcBuffer[i*3*width +j]+pcSrcBuffer[i*3*width +(j+1)]+pcSrcBuffer[i*3*width +(j+2)])/3;
k++;
j+=3;
}
k-=(2*width);
}


for (i = 0; i < width*(height-2)-2; i++)
{
i00=pcSrcBuffer[i ]; i01=pcSrcBuffer[i +1]; i02=pcSrcBuffer[i +2];
i10=pcSrcBuffer[i+ w]; i12=pcSrcBuffer[i+ w+2];
i20=pcSrcBuffer[i+2*w]; i21=pcSrcBuffer[i+2*w+1]; i22=pcSrcBuffer[i+2*w+2];

n= - i00 - 2*i01 - i02 +
+ i20 + 2*i21 + i22;

m= - i00 + i02
- 2*i10 + 2*i12
- i20 + i22;

K = abs + abs(m);
if (K > 255)
K = 255;

/* ---------------------------------------------------------------- */
/* Store it. */
/* ---------------------------------------------------------------- */
pcDestBuffer[i + 1] = K;

}
