Behind Image Pixels

Pixels work in certain ways. Most of us are not aware of the technology behind it. Questions like "How faces can be detected by the Blackberry Bold Touch? or how auto-tagging is possible on Facebook?" left unanswered. What used to be Science fiction has today become reality with "Behind Image Pixels" technology. Mr.Liang Kim Meng came down to KDU University College on 11th November 2011 presenting on the topic of "Behind Image Pixels" technology and its related applications. 

About Mr.Liang Kim Meng

He received his Master in Science (Image Processing) and Bachelor in Applied Science (Hons.) from Universiti Sains Malaysia in 2003 and 1999, respectively. He has devoted 15 years on working on and researching on image processing and pattern recognition fields. His successful commercial products includes 

"Pornographic blocking and detection system" for the X-Filter in TMNET. To top it off, he is also successful in the "Vehicle license plate recignition system and currently Automated video Surveillance system". He is also currently a Staff Reseacher at MIMOS (Centre for Multimodal Signal Processing). 

For his achievements, he has grant several awards, including Winner of "Best of Application and and Infrastructure in MSC-APICTA and Winner of ICT Product of the Year in PIKOM Computimes ICT in 2004 & 2005, respectively. Recently, he has also been awarded the Innovator Award by his affiliate company and has published more than 10 peer-reviewed International research publications in various countries, including Netherlands, Korea, Hong Kong, Singapore, India and Malaysia. He is also a certified Green Belt Six Sigma, Infrared Thermographer and Practitioner of TRIZ (Problem Solving Methodology).

The event marks on a very special date indeed!

A Pixel is the smallest element in any picture. Over the years, scientists and engineers have developed cutting-edge technology to uncover new and hidden properties of each image pixels. 

"A camera is now everywhere. It is in your cellphones, laptop and even the I-pad", he clarified.

Britain has a staggering 4.2 million CCTV cameras - One for every 14 people in the country- and 20 per cent of cameras globally (Source: Evening Standard, March 2007)

-An example he gave us on the "Sensor element" was the "Microsoft-Kinect" which uses sensor for the Xbox 360. The sensor enables users to control and interact using gestures to play games.

There are different camera types such as the  Analog camera, Network camera, Thermal camera and the Night Vision camera.  

The Night Vision camera would not be able to work if it is 100% dark, without any lights at all. It can be used  at the streets at night because there is the night moon.

The Thermal camera can be used in a total darkness surroundings as it uses to measure temperature. Example: The heat from human

The purpose of the "Lens"

The optic collects lights to point-sharp to the camera, to focus on the sensor.

There are 3 elements in the image pixels, namely:

-Motion detection (Some cameras have the ability to detect motions)

-Pattern recognition (Can be used for auto sourcing)

-Feature Extraction (Ability to extract "Shape", recognize colours as well as textures.

There are deeper understanding to this technology, but the experts themselves would only be able to implement and generate ideas from it. What he shared with us was just the surface on how this technology works in a different manner. It was definitely an interesting topic where participants gain basic knowledge of this technology. This makes them not only a user but a user with knowledge of this technology.
