The Lenna (or Lena) picture is one of the most widely used standard test images used for compression algorithms. The comp.compression FAQ says the following:
For the curious: ‘lena’ or ‘lenna’ is a digitized Playboy centerfold, from November 1972. (Lenna is the spelling in Playboy, Lena is the Swedish spelling of the name.) Lena Soderberg (ne Sjööblom) was last reported living in her native Sweden, happily married with three kids and a job with the state liquor monopoly. In 1988, she was interviewed by some Swedish computer related publication, and she was pleasantly amused by what had happened to her picture. That was the first she knew of the use of that picture in the computer business.
Today I came across a nice project: Sixth Sense, by MIT Media Lab. More than anything I would love to buy that tiny projector!!!! Wonder how much it cost. The project web site says,
‘SixthSense’ is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. By using a camera and a tiny projector mounted in a pendant like wearable device, ‘SixthSense’ sees what you see and visually augments any surfaces or objects we are interacting with. It projects information onto surfaces, walls, and physical objects around us, and lets us interact with the projected information through natural hand gestures, arm movements, or our interaction with the object itself. ‘SixthSense’ attempts to free information from its confines by seamlessly integrating it with reality, and thus making the entire world your computer.
University of California, San Diego computer scientists have built a software program that can perform key duplication without having the key. Instead, the computer scientists only need a photograph of the key.
In this “Sneakey” Computer Vision project, features of the key is extracted from the photograph and accordingly a duplicate of the key is produced. Most importantly, photos can be taken even 200 feet away from keys without the owners knowledge.
So it is time to blur out the your keys in the photograph, like you did for number plates, credit card numbers before publishing to facebook, flickr etc. )
If you are new to OpenCV or If you want to expand your knowledge in OpenCV you would find following book is useful. I’ve been using OpenCV for almost 6 years up to now. It is “the” Open Source Computer Vision Library out there.
I found this interesting article  at NewScientistTech written by Kurt Kleiner. They have a nice approach to create a curved digital sensor (spherical) mostly using conventional photolithography. There can be endless applications since this will help to get wide-angle but less distorted images from a small camera. Also the author suggests, these can be used in military surveillance as well as in medical applications. Read on for more information on how they created the sensor.
Extracted from the Article:
Mimicking the curves of a human retina has enabled a digital image sensor to take wide-angle pictures without distortion. This is possible thanks to an improved method of transferring silicon sensors onto a curved surface.
They built their hemispherical electronic eye by first using conventional photolithography to build silicon photodiodes 500 micrometers square and 1 micrometer thick. These were then wired into a flexible 16-by-16 array using chromium and gold.
Separately, they created a 1-cm-wide hemisphere out of a stretchy plastic, and stretched it into a flat surface. That stretched surface, or “drumhead”, was then pressed against the photodiode array.
The silicon squares stuck to the stretched plastic thanks to van der Waals forces, which was then allowed to spring back to its original hemispherical shape. As the array took its new form, the photodiodes packed together tightly and the connecting wires arced away from the surface, but the array was undamaged.
The reformed array was then glued to a curved glass surface, and a conventional lens attached. It now resembled a human eye in construction, with light entering the lens from the front, and passing to the curved “retina” containing the matrix of photodiodes behind.
It didn’t take too long for me to get rid of the previous “black” WordPress theme I’ve been using. But the most immediate reason was some encouragements given by few friends.
Okay, that is how the fun began! .
First, I wanted to use the layout I used back in 2004. Second, I wanted to make it a WordPress theme.
After extensive work with Photoshop, theme was okay to proceed to CSS design level. I found Guides and Slice Tools really useful in Photoshop. After playing with CSS a bit, the theme was ready to upload. There are few glitches here and there, but decided to deal with them later. The theme was tested in Firefox, Chrome and IE.
 and  tutorials made my life so easy. However, M$ Internet Exploder gave me enough trouble. Specially with the Sidebar. If I make a small change in a width of a DIV tag, the sidebar goes and sits right at the bottom of the screen.
