Pixelation

mainPixelation is the display of a digitized image where the individual pixels are easily visible to a viewer. This can happen unintentionally when a low-resolution image designed for an ordinary computer display is projected on a large screen. In this situation, each pixel becomes separately viewable. It’s not pretty! Pixelation is also sometimes used to describe the act of turning a printed image into a digitized image file. As the image is captured, it is processed into a vectorized or rasterized file that can be used to illuminate color units (called pixels) on a display surface. So why does it happen? What exactly happens in there?   Continue reading

Panoramic Images


Consider a situation where you are standing on top of a mountain or some other beautiful natural scenery. You are enjoying a beautiful view that seems to span from far left to far right and you want to take a nice picture of the whole thing. Your camera allows you to capture only a limited field of view. So to capture the whole scene, you will have to capture multiple images. Doesn’t feel exactly the same watching it in pieces, does it? We really want to capture the beauty within a single image. You can certainly record a video and capture the whole scene, but what if you want to print it out? This is where panoramic photography technique comes in. Panoramic images are images with elongated field of view. The image above is one such example. These images cannot be captured with a single camera click because the field of view is limited. So how do we do capture panoramic images?   Continue reading

Connecting With Kinect

If you haven’t experienced Kinect yet, do yourself a favor and just go do it! For people who have just landed on earth, Kinect is a motion sensing device for Microsoft XBox 360 video game console. You can check out the video here. Instead of using buttons or controllers to play video games, this device enables you to use your body. Your movements will be captured and the video game character will move accordingly. When Kinect first came out in 2009, it took the world by storm! How is it possible to capture our body movements so accurately without using any wires? How does it recognize our gestures?   Continue reading

Peeking Into The Third Dimension With 3D Glasses

Instead of directly explaining it, I will take a different route this time. Let’s take a look at this conversation between Walter and Michael. In case you are not familiar with them, Walter is a mathematician and Michael is his friend who refuses to acknowledge that humans need complex mathematical models. This attitude of Michael doesn’t sit well with Walter and hence they are constantly at loggerheads over this issue. They were once walking along and they came across a multiplex.   Continue reading

Looking Into The Future With Google Glass

Unless you shut down all your gadgets and hid yourself in a dark alley with absolutely no connection to the rest of the world, you would have heard that the Google I/O conference started on June 27. It is one of the most exciting events in the realm of tech innovation. Google came up with a couple of new devices – A 7-inch Android Jelly Bean tablet called Nexus 7 and a social media streaming device called Nexus Q. But that’s not what this blog post is about. I want to talk about the insanely cool Google Glass demo that they presented in the conference. If you haven’t seen it yet, you can see it here. This reminded all of us why we love and adore Google. The technology falls in the category of Wearable Computing. When they started it out a few years ago, it sounded very futuristic, but not anymore. It’s here and we just saw it!   Continue reading

Understanding Camera Resolution

Cameras are being embedded everywhere. We find them on our phones, tablets, laptops and other types of gadgets as well. Digital cameras are getting sharper and smarter by the day. Some cameras capture good quality pictures while some cameras don’t. We frequently come across the camera specs which mention the ‘MP’ value of the camera. You understand the fact that a 12MP camera takes better pictures than a 5MP camera. Have you ever stopped to think what makes it better? More pixels means better pictures. Why exactly is that?   Continue reading

Good Things Come In Small Packages

We encounter digital images everyday. We see a lot of JPEG files on our computers, cameras, phones and tablets. The actual images are huge and it should actually take up a lot of space to fit in all that data. But somehow our machines are able to compress all those images and store everything compactly. Ever wondered how it’s possible to fit so many images in such small space? How can the JPEG algorithm achieve so much reduction in size without visibly losing the image quality?   Continue reading
