Reverse Painter's Algorithm

Reverse painter's algorithm is logically enough, the reverse of painter's algorithm. Painter's algorithm is a 3D rendering method where each object is rendered in turn, starting with that which is furthest away from the viewpoint, and then successively closer items are rendered. Reverse painter's algorithm, operates the other way round, drawing the closest objects first, then working backwards. The governing rule is that rather than testing for clipping in the normal way, the display area is tested from the viewpoint, pixel by pixel. If there is already something there, regardless of what it is, don't 'paint' another object. Thus, reverse painter's algorithm is actually a fairly fast and efficient render method.

It does still suffer the fatal flaw of painter's algorithm. If you have multiple objects, which overlap one another, such that both objects are both in front of, and behind one another, the algorithm grinds to a halt, trying to work out which object to tackle first.

Reconstructing Cities in a Day
A computer algorithm developed at the University of Washington uses hundreds of thousands of tourist photos to automatically reconstruct an entire city in about a day.

WARP: Accelerating Wireless Technology Development
Prior to 2006, any attempt at investigating wireless technology, developing a new algorithm for propagation, or even trying for a whole new standard, all shared one thing in common: The phenomenal expense for the research team.

The Omni-focus
The omni-focus is a camera system with the ability to function much like the human eye - capturing objects in its field of vision regardless of the distance, in perfect focus. It even adapts an algorithm from VR, in order to do so.

Reverse Engineering The Ability to See
There are a few, albeit exceedingly rare cases, where after a lifetime of blindness, a human's vision is naturally restored. These cases, properly studied, are yielding impressive amounts of data on how a vision system forms in a mature mind - and thus how to recreate the same, in machine vision.

Rewiring the Brain: Inside the New Science of Neuroengineering
A wired article about Dr Ed Boyden and his lab, at the cutting edge of applied neuroscience. A fairly lengthy and in depth article on the process of reverse engineering and enhancing the brain, and showcasing the state of development of the science as of early 2009.

Vulnerability in Networked Prosthetics Exploited

Industry news, originally posted 23-10-2012, deemed too important to allow to fade. At the breakpoint 2012 cybersecurity conference on the 18th of October, Barnaby Jack, a Research Architect with the TRACE research team at McAfee, demonstrated a critical weakness in pacemakers. Specifically, he was able to reverse-engineer the specs of the transmitter contained in every modern pacemaker – used to update firmware without requiring additional open heart surgeries – with lethal consequences.
