Color interpolation in OpenCV
23
Dec
I could not find in Internet a function which can return a RGB color value between two colors So I had to do it myself. I hope it will be useful for someone.
CvScalar interpolate(CvScalar c1, CvScalar c2, double value){
if( value <= 0.0 ){ return c1; }
if( value >= 1.0 ){ return c2; }
int red = cvRound((1.0 - value) * c1.val[2] + value * c2.val[2]);
int green = cvRound((1.0 - value) * c1.val[1] + value * c2.val[1]);
int blue = cvRound((1.0 - value) * c1.val[0] + value * c2.val[0]);
return CV_RGB(red, green, blue);
}
Find alternative to your softwares

Tired of crappy software?
AlternativeTo is a new approach to finding good software. Tell it what application you want to replace and we give you great alternatives, based on user recommendations. It is a new website which I believe that it will help to help open source software to find its users because nowadays you can find an alternative to any payed and proprietary software.
In the website I found a citation which I liked a lot:
“Whether you’re looking for an alternative to expensive commercial software or just trying to get a feel for what’s out there, AlternativeTo is a handy service for finding software alternatives.”
Easy way to get Un social networked

It may sound wired, but it looks a good idea which I was looking for for a long time. The most annoying in social networks that it is easy to enter but once you are in, you can not stop it. Today I found this online service that I hope it will do what I could not do by myself.
Social networks are our today’s big mistake of technology. I see internet as a tool to help connecting the world but when it comes to social networking it go beyond the limit of privacy and common sense. I don’t say it is a mistake of Internet, It is a mistake of human who use it for one purpose to cash in on naivety of people and serve them targeted advertisement and break their natural defenses of strangers fear.
Using this tool, it will delete all you information and change your account so it becomes un-useful.

Google Wave is a project announced by Google at the Google I/O conference on May 28, 2009. It is a web application and computing platform designed to bring together e-mail, instant messaging, wiki, and social networking, with a strong collaborative focus, mixed with spellchecker and translator extensions, which are able to work in concert, in real-time. It is planned to be released later in 2009.
