This video shows in a funny way, what is Goole Wave.

This a simple implementation of Polar to Cartesian transformation applied to the image case. It is useful to unroll an omni image to convert it to panoramic image.
imgPol = cvCreateImage(cvSize(2*CV_PI*RadiusMax,RadiusMax-RadiusMin),IPL_DEPTH_8U,1);
cvSet(imgPol,CV_WHITE,NULL);
int x0,y0;
double Radius;
double Angle;
for(int x=1; x < imgPol->width; x++)
{
for(int y=1; y < imgPol->height; y++)
{
Radius = RadiusMin + y;
Angle = 2 * CV_PI * x / imgPol->width;
x0 = cvRound(CenterX + Radius * cos(Angle));
y0 = cvRound(CenterY + Radius * sin(Angle));
cvSet2D(imgPol, y, x, cvGet2D(imgBase,y0,x0));
}
}
cvSaveImage("imgPol.bmp",imgPol);
My specialty is robotics, but this time I made another kind of robot: it is a chat robot.
The idea is simple. you chat with my robot in any Jabber client like Google talk.
You can try to add “kristou@bot.im” to the list of your friends and start a conversation.
For the moment, it is just simple. I made it only as a proof of concept and to have a hand on.
If you like it, or you think it is useful. just drop me a comment and I will try to implement it.
This bot also work on Twitter, Facebook, MSN messenger, Yahoo messenger, AIM…
For the moment only Jabber network is working. If you want to try it with above networks just let me know.
I like this tutorial. So I wanted to share it.
