Why you can’t increase the resolution of an image

low resolution imageOne of the core understandings in computer graphics is that if you want a high resolution image, you must start with a high resolution image. Forget all the tv shows that you’ve seen where the person is standing behind a computer technician asking them, “Can you sharpen the image a little more?” The computer technician¬† maybe clicks a few buttons and the suddenly the license plate that was too blurry to read becomes crystal clear. It’s a miracle, the computer can do anything! Sorry, that isn’t real life, at least with current technology. A computer can do a lot of things, but when it comes to enhancing low resolution imagery the computer at best must ‘guess’ what the image is.

To understand this concept it helps if you understand the way an image is formed on the computer. If you were to zoom in as far as you could on any image, you would see a collection of different colored squares, these squares are called pixels. To a computer, that image isn’t a photo of anything, it is just as I said, a series of pixels placed in a particular way that when viewed by humans looks like you, your dog, Continue reading

This immersive tech turns your memories into beautiful abstract art.

Maybe it’s colorful for your happy memories, and maybe dark for your sad ones.

According to an article on Mashable.com, “A London-based creative technology studio, Random Quark, has found a way to visually and directly represent emotions by scanning people’s brains to create awe-inspiring paintings.”

In all honesty they really don’t show a lot of the end result, but the premise of idea is intriguing to say the least. I mean, could you create a work of art based only on your memories? Could you explain your perspective of an event based on memories? Imagine someone looking at your past and seeing how bad you felt or how happy your were based on this technology. Is it a huge step to think that this could be used as a medical tool. I don’t know, but it would seem that some medical professionals would benefit from knowing what an event meant to you.
