Morphing and merging images

// October 22nd, 2009 // No Comments » // Representing Earth

Here is another example of the Bullet Time effect, but on a much more affordable scale than the Matrix budget. Using disposable digital cameras they managed to put together a rig to experiment with the effect. The focus on this project was to use the resulting images as a basis for temporal-spatial experimentation in relationship to the viewer. You can see videos on the project’s site.

In thinking about the idea of morphing and merging, the terminology leads me to think of a distorted representation of reality. In regards to distortion, Slit-Scan images come to mind as a good example of this relationship. Golan Levin has compiled “An Informal Catalogue of Slit-Scan Video Artworks and Research”. As well there are some ITP folks who have experimented with this technique and some basic processing sketches you can try out if you are interested in doing some tests of your own. To focus on an example that relates well to the nature of this course, Michael Awad created a work called “The Entire City Project”. The basic idea of the project was to take panoramic Slit-Scan images of a significant portion of the city of Toronto and then assemble them into an installation within the city’s major airport. In a related project, he teamed up with Evan Penny using portraiture to turn these types of images into 3D representations.

As another example of people creating misleading representations of reality, here are a few links to do with Polar Panoramas (aka little planets). There is a flickr group dedicated to these images if you would like to see more examples. If you would like to try creating any there are plenty of tutorials in the forum.

How we experience space (virtually)

// October 8th, 2009 // No Comments » // Representing Earth

Focusing on the way we try to enhance the experience of how we experience space in virtual ways, here are a few examples with varying approaches.

The Helio Display is another example of trying to replicate the experience of holography. The image itself is 2D, but because it is projected into compressed air and has no backdrop as a frame of reference, the image looks 3D if projecting the right content. It also functions as an interface as well as a projection system. You can see it in action here:

The next example is an effort to enhance the quality of video to make it seem more like a true representation of the content it displays. You can see how they approach the idea here:

The last example is in reference to the way we experience space in recorded video. This isn’t the first attempt at this process, but seems to be one of the most recent. The interesting thing I find with this example however, is the thought of replicating this process as a live stream. Here is the setup they use:

Making History and visualizing millions of photos

// September 24th, 2009 // No Comments » // Representing Earth

This year the National September 11 Memorial & Museum and Google teamed up to create “Making History“. The site is “a collective telling of the events of 9/11 through the eyes of those who experienced it, both at the attack site and around the world”. The site uses user submitted photos and videos and overlays them into street view images.

Mapping the World’s Photos

“The recently presented academic paper at the WWW 2009 Conference from a group of computer science academics from Cornell University investigates the collection of roughly 35 million geotagged photos collected from Flickr, uploaded by more than 300,000 users. Their approach used in Mapping the World’s Photos combines content analysis based on text tags and image data with structural analysis based on geospatial data. While individual users of Flickr are simply using the site to store and share photos, their collective activity reveals a striking amount of geographic and visual information about the world.”

10×10

From the site: “10×10™ (‘ten by ten’) is an interactive exploration of the words and pictures that define the time. The result is an often moving, sometimes shocking, occasionally frivolous, but always fitting snapshot of our world. Every hour, 10×10 collects the 100 words and pictures that matter most on a global scale, and presents them as a single image, taken to encapsulate that moment in time. Over the course of days, months, and years, 10×10 leaves a trail of these hourly statements which, stitched together side by side, form a continuous patchwork tapestry of human life.”
