This 360° amphibious camera takes its optical design from the eyes of fiddler crabs

One of the big problems you encounter when moving a camera from dry land to under the water is the difference in the index of refraction (IOR). That’s the thing that often makes rivers and lakes appear much shallower than they actually are when you’re looking at them from the water’s edge. For 360° cameras, this difference in IOR can be a big problem when it comes to shifting from the air to underwater.

A team of researchers at the Institute for Basic Science (IBS), Massachusetts Institute of Technology (MIT), the Gwangju Institute of Science and Technology (GIST), the Seoul National University and The University of Texas at Austin, though, have developed a system based on one of nature’s designs. They’ve taken inspiration from the fiddler crab to develop a 360° camera system that works both in and out of the water.

Scientists develop stamp sized ultrasound patches that create images of your internal organs

by Leave a Comment

From unborn babies in the womb to kidney stones, ultra sound technology is a marvelous thing. It allows us to see inside our bodies in a non-invasive way. It’s been used as a diagnostic tool in medicine for sometime now, at least 50 years and generally it requires a specialist radiologist or sonographer and bulky machines.

Scientists at MIT want to change all that and have invested an ultrasound ‘patch’, a little like a Nicorette patch, which can be sold in pharmacies or used in small doctor’s practices. And it’s the size of a postage stamp.

These creepy images were completely generated by AI from just photo captions

AI just gets weirder and weirder. And creepier. Researchers at the Allen Institute for AI have published new research which builds on OpenAI’s GPT-3 machine learning tech to generate images from scratch based just on the captions of photos.

It’s kind of the reverse of what Facebook does when you upload a photo to the platform and it generates captions. Here, you feed it captions and it generates the photo.

Engineers at MIT & UMass Lowell have created a completely flat 1mm thick fisheye lens

by Leave a Comment

Love them or hate them (and many people hate them), we all know what fisheye lenses are. They look sort of like regular lenses, except they have a great big round bulbous element on the front that lets your camera’s sensor see in a super-wide field of view – typically around the 180° degree mark.

Well, not anymore. Now a team at MIT and University of Massachusetts Lowell have developed a new fisheye lens that’s completely flat. Its design is a type of “metalens” – a wafer-thin material with microscopic features to manipulate light in a way that traditional optics don’t. And it lets the lens shoot a 180° field of view with perfect sharpness.

This camera can photograph a subject from 28 miles away

by 1 Comment

Computational imaging has given us some interesting and useful inventions so far, from fake bokeh to capturing the movement of light. This time, scientists have figured out how to take a clear image from as far as 28 miles (45km), regardless of the Earth’s curvature and the amount of smog in the air.

These MIT cinematography drones get the perfect shot every time

by Leave a Comment

Drone technology has come on so quickly in such a short space of time. Especially the camera technology. I’m not just talking about the quality of the optics and sensors, either. The “brains” behind the visual  systems in drones now is just nuts. Even modest consumer drones have facial recognition, subject tracking, and similar features. All these features and help us to achieve the best shot possible.

A team of research from MIT and ETH Zurich have now taken things way beyond that which is currently available to the masses. Building on the basic visual systems, theirs actually allows you to determine where in the frame the subject is positioned. It also lets you choose the camera angle. If you want full frontal, you got it. 3/4 left or right? No problem, it’s just the flick of a menu item.

Tiny vibrations bring still photos to life in dynamic interactive images

by 2 Comments

A photograph is, by its very nature, a still image. Good ones perform their task very well. As technology has evolved the lines between photo and video have started to become a little blurred. We’ve got live photos, Instagram supports video, and now wants to be SnapChat.

Then we have augmented reality. The combination of computer generated data and real world imagery in real time.

The big problem with augmented reality is that the two don’t really mix together too fluidly yet. MIT PhD student Abe Davis has figured out a possible way to solve this problem. It’s a process he calls Interactive Dynamic Video. It uses tiny vibrations picked up in video to simulate real world movement in still images.

Google & MIT’s New Algorithm Uses Edge Detection To Remove Reflections From Photos

by 8 Comments

A team of researchers from MIT (Tianfan Xue, Michael Rubinstein, Ce Liu and William T. Freeman) are teaming up with Google with to present a new algorithm that is able to extract photographic inconveniences such as glares and reflections from photographs. The algorithm can then reproduce the image free of any reflections, in addition to being able to create an additional image of the reflection itself. This kind of problem solving would be especially useful when shooting behind glass or a fence, for example.[Read More…]

MIT Researchers Developed an Algorithm That Removes Reflections

by 1 Comment

Windows have been ruining photos ever since the first time a photographer tried shooting through one.

Unless you bring along dedicated contraptions or start messing around with cloths and funny angles, shooting through the glass will likely lead to an annoying reflection that will make you want to smash it to pieces. (If you’re actually trying to get a reflection then scratch everything I said; windows are awesome).

This problem might soon come to an end, though; as researchers say they’ve developed an algorithm that can automatically remove reflections from digital photos. The algorithm can’t remove all types of reflections, but it does an impressive job with the ones it can remove.

High Speed Camera Allows Scientists To Photograph The Smell Of Rain

by 1 Comment

 

Ah, the smell of fresh rain. Clean, refreshing, and light…There’s nothing else quite like it. And, unfortunately, according to a team of researchers from MIT, that nostalgic aroma of a rain shower could also be loaded with hazardous viruses and bacteria. This interesting discovery was made possible through the use of high speed cameras, which the scientists used to record “roughly 600 experiments on 28 types of surfaces”, where a drop of water was released onto each of the 28 varying soil surfaces. The scientists then took their high speed footage and played it back at 1/250 of the actual speed.

Their findings showed that, upon making contact with the surface, air bubbles were trapped between the soil surface and the drop of water. This resulted in the trapped air to be forced upwards through the drop of rain, effectively creating an aerosol effect. This entire process, scientists believe, is essentially how the “smell of rain” is created.[Read More…]
