The USD 500 camera could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
The three-dimensional camera was developed by researchers in the Massachusetts Institute of Technology Media Lab. The camera is based on “Time of Flight” technology in which the location of objects is calculated by how long it takes a light signal to reflect off a surface and return to the sensor.
However, unlike existing devices based on this technology, the new camera is not fooled by rain, fog, or even translucent objects, said co-author Achuta Kadambi. “Using the current state of the art, such as the new Kinect, you cannot capture translucent objects in 3-D,” said Kadambi, a graduate student at MIT.
“That is because the light that bounces off the transparent object and the background smear into one pixel on the camera.
Using our technique you can generate 3-D models of translucent or near-transparent objects,” Kadambi added.
In a conventional Time of Flight camera, a light signal is fired at a scene, where it bounces off an object and returns to strike the pixel.
Since the speed of light is known, it is simple for the camera to calculate the distance the signal has travelled and therefore the depth of the object it has been reflected from. The new device uses an encoding technique commonly used in the telecommunications industry to calculate the distance a signal has travelled, said Ramesh Raskar, an associate professor of media arts and sciences.
Raskar was the leader of the Camera Culture group within the Media Lab, which developed the method alongside Kadambi, Refael Whyte, Ayush Bhandari, and Christopher Barsi at MIT and Adrian Dorrington and Lee Streeter from the University of Waikato in New Zealand.
In 2011 Raskar’s group unveiled a trillion-frame-per-second camera capable of capturing a single pulse of light as it travelled through a scene. The camera does this by probing the scene with a femtosecond impulse of light, then uses fast but expensive laboratory-grade optical equipment to take an image each time.
This “femto-camera” costs around USD 500,000 to build. In contrast, the new “nano-camera” probes the scene with a continuous-wave signal that oscillates at nanosecond periods.
This allows the team to use inexpensive hardware off-the-shelf light-emitting diodes (LEDs) can strobe at nanosecond periods, for example – meaning the camera can reach a time resolution within one order of magnitude of femtophotography while costing just USD 500.
The MoU covers eight areas of co-operation including human resource management, e-governance, public delivery system, accountability and transparency, skills and capacity building and quality results.
The MoU was signed by Malaysia’s Public Service Department Director-General Mohamad Zabidi Zainal and the Secretary of India’s Department of Administrative Reforms and Public Grievances of Ministry of Personnel, Public Grievances and Pensions, Sanjay Kothari.
Zabidi said the MoU was a strategic cooperation and collaboration to strengthen ties between the two countries. He added that apart from that it could also assist in socio-economic development through an efficient, accessible, transparent and accountable civil service.
The MoU envisages cooperation via tours, workshops and conferences, sharing of public administration and governance information and expertise, common project implementation mechanisms and exchange of publications, state-run news agency Bernama said.
There was no surprise in the first full policy unveiled by new RBI Governor Raghuram Rajan, who increased the repo rate, as was widely expected, by 0.25 per cent to 7.75 per cent and brought down the cost of short-term funds for banks by slashing the marginal standing facility (MSF) rate by a similar quantum to 8.75 per cent.
The policy stance and measures, Rajan said, “are intended to curb mounting inflationary pressures and manage inflation expectations in a situation of weak growth. “These will help strengthen the environment for growth by fostering macroeconomic and financial stability. The Reserve Bank will closely monitor inflation risk while being mindful of the evolving growth dynamics,” he said.
The central bank reduced the growth forecast for the current fiscal to 5 per cent from 5.5 per cent projected earlier. Economic growth fell to a decade-low of 5 per cent in the previous financial year.
The RBI left other rates unchanged, such as the cash reserve ratio at 4 per cent, and mandatory holdings in government securities and other liquid assets as a solvency measure (SLR) at 23 per cent.
However, the Governor doubled the borrowing limit of banks against their cash positions or NDTL to 0.5 per cent for both 7-day and 14-day repos, with immediate to increase liquidity in the system.
Following are the highlights of the RBI’s second quarter review of monetary policy 2013-14 :
* Repo or short-term lending rate up by 0.25 pc to 7.75 pc;
* Cash reserve ratio unchanged at 4 pc
* Marginal standing facility (MSF) rate cut by 0.25 pc to 8.75 pc
* Difference between repo and MSF rate narrows to 1 pc
* Repo hiked due to upturn of inflation, other factors.
* Wholesale inflation expected to be higher than current levels; warrants ‘appropriate policy response’
* Retail inflation to hover around 9 pc
* Food price pressures may ease with the arrival of summer crop harvest and seasonal moderation.
* Prospect of delay in taper of US Fed Reserve’s bond purchases has brought calm to financial markets
* Normalcy will restored in the forex market only when OMCs fully return to the market for their demand
* FY14 GDP growth estimate revised downward to 5 pc vs 5.7 pc
* Growth likely to pick up in second half on good show in exports and agriculture
* Liquidity pressures building on small businesses as large entities holding on payments; remedies lie in speeding-up of Government and PSU payments.
* Average drawdown from MSF has declined to Rs 0.4 trillion by mid-Oct, down from a high of Rs 1.4 trillion in mid-Sep
* Final guidelines on unhedged forex exposures by corporates to be out by December
* Jalan panel on new bank licenses to hold 1st meet on Nov 1, decision of RBI on in-principle approvals will be final.
