Introduction to Video Scaler

1. Amplified magnetic resonance imaging of video scaler

Amplified magnetic resonance imaging (aMRI) is an MRI method which is coupled with video magnification processing methods to amplify the subtle spatial variations in MRI scans, to enable better visualization of tissue motion. aMRI can enable better visualization of tissue motion to aid the in vivo assessment of the biomechanical response in pathology. It is thought to have potential for helping with diagnosing and monitoring a range of clinical implications in the brain and other organs, including in Chiari Malformation, brain injury, hydrocephalus, other conditions associated with abnormal intracranial pressure, cerebrovascular, and neurodegenerative disease.

The aMRI method takes high temporal-resolution MRI data as input, applies a spatial decomposition, followed by temporal filtering and frequency-selective amplification of the MRI frames before synthesizing a motion-amplified MRI data set. This approach can reveal deformations of the brain parenchyma and displacements of arteries due to cardiac pulsatility and CSF flow. aMRI has thus far been demonstrated to amplify motion in brain tissue to a more visible scale, however, can in theory be applied to visualize motion induced by other endogenous or exogenous sources in other tissues.

aMRI uses video magnificent processing methods such which uses Eulerian Video Magnification and phase-based motion processing, with the latter thought to be less prone to noise and less sensitive to non-motion induced voxel intensity changes. Both video-processing methods use a series of mathematical operations used in image processing known as steerable-pyramid wavelet transformation to amplify motion without the accompanying noise. The MRI temporal data undergoes spatial decomposition, followed by temporal filtering and frequency-selective amplification and can allow one to visualize in vivo tissue and vascular motion that is smaller than the image resolution.


2. Use in blended/flipped classroom learning of video scaler

SPOCs support blended learning and flipped classroom learning, which variously combine online resources and technology with personal engagement between faculty and students. Early research results point to improved learning and student outcomes using such approaches.

In spring 2013, edX and MITx piloted two blended classroom implementations of 6.00x, Introduction to Computer Science and Programing at Bunker Hill and Mass Bay Community Colleges. The program was funded as part of a Bill and Melinda Gates Foundation grant. Students enrolled in the pilot courses completed the same exams as the 6.00x MOOC students, and scored an average of 10 points higher than their MOOC peers.

When a SPOC is implemented at an institution, in concert with students, faculty determines which features and course content to utilize. This can include video lectures, assessments (with immediate feedback), interactive labs (with immediate feedback) and discussion forums used in MOOCs. Using MOOC technology allows the faculty to organize their time with students in different ways, such as allowing more time in class for project-based work instead of grading assignments or preparing lectures. SPOCs have been analogized to next generation textbooks, by allowing faculty to decide how to use some or all parts of the SPOC. In a SPOC as in a MOOC students typically access interactive content at their own pace. Instructors set their own grading scale.

Colleges and universities can create SPOCs, or license them. In the latter instance, a SPOC might give the instructor an opportunity to deliver the material directly to students using video delivered by another expert, instead of assigning an article to read. Harvard University announced SPOCs for its curriculum in the fall of 2013. Unlike MOOCs, SPOCs have limited enrollment and are often used as part of a course for credit.

4. Carhenge: Genius or Junk? of video scaler

Carhenge: Genius or Junk? is a 2005 documentary film about Carhenge, an artist's almost-to-scale interpretation of Stonehenge, but built with automobiles instead of megaliths. Located in Western Nebraska, Carhenge has become a huge tourist attraction and also a center of local controversy.

In the film, creator Jim Reinders challenges a community's definition of art, freedom of political expression, and appropriate land use development. This documentary focuses on Reinders' effort to erect the monument, and to then keep it from being dismantled. It also addresses aspects of public art and how, in many forms of art, the creative effort is often more about group unity than about the final end-product. The program runs 26:40.

The director, David Liban is a professor at the University of Colorado Denver.

This film has been broadcast on Public broadcasting stations nationally, Israeli television, and at the following film festivals and conferences:

Australian International Film Festival, Melbourne, Australia, Oct 2006

5. Exhibits and events of video scaler

In 2000 and 2001, the Townhouse Gallery contributed to the establishment of the Nitaq Festival in Cairo, which was an art festival situated in downtown that aimed to expose the contemporary art scene to the public. The festival included multimedia video installations that were created by various artists including Lara Baladi, Amina Mansour, Hassan Khan, Wael Shawky and Mona Marzouk. Townhouse also initiated Egypt's first exhibition dedicated to photography in 2002, calling it PhotoCairo, with the aim of exposing the public to the various forms of self-expression that are evident in the world of photography. This event proved to be quite successful in 2002 so the event was repeated in 2003 and 2004, accompanied by the Open Studio Project.

Recent exhibits that have been on display during February and March 2010 in the Townhouse Gallery include The Girl Splendid in Walking by Doa Aly and Making A Man Out of Him by a Professor at the American University in Cairo, Huda Lutfi. Both works have proven themselves quite unique to their audiences, each providing a specific experience to the visitors of the Townhouse Gallery.

Regarding Doa Aly's work, the video installation, inspired by Wilhelm Jenson's Gradiva, includes scenes where the girl was in a room, walking and tracing the sunlight with her feet as it beamed through the window, like she was going after the light. Meanwhile, Lutfi's Making a Man Out of Him, uses the symbolism of the male anatomy as a means of criticizing society's perspective on masculinity. This illustrates how the Townhouse Gallery has the ability to display art that may be viewed as controversial.

7. Online video of video scaler

After releasing Rocketboom in late 2004, Baron established himself as one of the first vloggers and arguably one of the most influential. With Rocketboom, Baron built one of the first large audiences around a video show, and went on to generate the first large-scale advertising deals.

On August 19, 2005, Baron was interviewed on CBS Evening News. In an "Eye on America", segment CBS veteran Jim Axelrod commented on the effort at daily news coverage on a limited budget and Baron's early grasp of the next Internet wave. "You know what they call that? Vision."

Baron directed a portion of "Killer," an episode of CSI: Crime Scene Investigation which aired February 2, 2006.

Steve Jobs featured Baron's Rocketboom on stage when releasing the video iPod and again when releasing the AppleTV

In March 2006, Baron commented on the sale of a week of advertising for $40,000 on eBay in Brandweek:

"Advertising with us has extra value because we aren't going to accept advertising from someone whose morals are against us, someone like Hummer," said Rocketboom producer Andrew Baron. The creators of the show are acting as ad agency as well as media for the ads for TRM and EarthLink. "We've got to approve the ads and if we like them, chances are our viewers will like 'em."In 2008, Baron created the first version of the Know Your Meme database, to accompany a spin-off show he created and produced for Rocketboom.

Also in 2008, with one of the most followed Twitter accounts, Baron made international news when he put his Twitter account up for sale on eBay.

Baron released his third major site, Magma, in 2009.

In 2011, Baron sold Know Your Meme to Cheezburger in a reported "low seven-figure deal".
