ABSTRACT
Smart cameras are rapidly finding their way into intelligent surveillance systems. Recognizing
faces in the crowd in real time is one of the key features that will significantly enhance
intelligent surveillance systems.
The main challenge is the fact that the enormous volumes of data generated by high resolution
sensors can make it computationally impossible to process on mainstream processors. For
security,such systems are usually installed in areas where crime can occur such as banks and car
parks.
The difference between digital cameras and smart cameras is that digital cameras just capture
images but smart cameras capture high level descriptions of the scene and analyze what they see.
For detection and recognition we use both low level processing and high level processing
algorithms. Smart camera architecture is described whereby a combination of an on-board
microprocessor and PLD’s allow for the embedding of image processing algorithmsin the
camera.

INTRODUCTION
A smart camera performs real-time analysis to recognize scenic elements. Smart cameras are
useful in a variety of scenarios: surveillance, medicine, etc. Trimedia processor. Our
system can recognize ge s tu r e s a t t he r a t e o f 20 f r ames / s econd . A "smart camera" is
basically a video camera coupled to a computer vision system in a tinypackage. This communication
begins stating the main differences between smart cameras and standard smart vision
systems. Smart camera architecture is described whereby a combination of an on-board
microprocessor and PLD’s allow for the embedding of image processing algorithmsin the
camera. A static thresholding algorithm is presented which demonstrates the ability
totrack non-uniformity in the inspection target. Finally, a prediction is made of
technological and applicational future evolutionon smart cameras.T h e s m a r t c a m e r a – a

u s e d anywhere, in any industry where image processing can be applied. Companies no longer
need acabinet in which to keep all their computing equipment: the computer is housed within the
smartcamera. In the pharmaceutical industry and in clean rooms – when not even dust is allowed
– thiscan be a big advantage. A single square meter of space can be comparatively very
expensive – if there is no need for a component rack or cabinet, simply a smart camera, and then
this could savea lot of money. In particular, there would not be the usual cabling
involved for other visionsystems, and set-up is simple. Later in this communication are stated
some advantages of usingsmart cameras or PC-based systems in vision applications.In usual
vision systems scenarios, only a small fraction of a picture frame will be the region of interest
(ROI). In fact, often no visual image of the ROI is even required. What if all that pixel pre-
processing and decision-making could be done within the camera? If allthe processing were done
inside the camera, the blob analysis of a gigabit image might result inonly a few hundred
bytes of data which need to be sent somewhere. Such compact packets of data could
be easily transmitted directly to a machine control without even passing through a
PC.Information should be processed where the information occurs – i.e. the brain should be
behindthe eyes!The answer to the problem stated earlier is a stand-alone, smart camera.

LITERATURE SURVEY
This literature review provides a discussion of areas related to the qualitative research
undertaken by me. The majority of these areas have been selected primarily in line with a need to
position smart cameras within the wider context of historical, present and future considerations.
Other areas were selected for discussion because of a need to highlight their importance and
identify areas that require particular attention in order for smart cameras developments to cater to
the needs of particular audiences, an example of this in particular is the area of hd recording.
The idea to this project initially was gathered from an advertisement on television showing a
smart camera named “Samsung Galaxy Camera”. Detailed study and references were taken
from various sources including web articles.
A white paper titled “10 Truths About Smart Cameras” by Matrox Imaging was thoroughly
studied and referenced.
Other web articles that were studied are provided in the refrences column at the end of this
synopsis. The major website that was referenced was “www.samsung.com” .

MERITS AND DEMERITS MERITS
Cost - Smart cameras are generally less expensive to purchase and set up than the
PCbased solution, since they include the camera, lenses, lighting (sometimes),
cabling and processing.
Simplicity - Software tools available with smart cameras are of the point-and-
click variety and are easier to use than those available on PC's. Algorithms come
pre-packaged and do not need to be developed, thus making the smart camera
quicker to setup and use.
Integration - Given their unified packaging, smart cameras are easier to integrate
into the manufacturing environment.
Reliability - With fewer moving components (fans, hard drives) and lower
temperatures, smart cameras are more reliable than PC's.
DEMERITS
Security : Due to inclusion of an operating system and many applications one’s
security and privacy can be compromised.
Sluggish : Due to multiple applications running at the same time a smart camera
may be sluggish sometimes.

APPLICATIONS
Smart cameras can in general be used for the same kind of applications where more
complexvision systems are used, and can additionally be applied in some
applications where volume, pricing or reliability constraints forbid use of bulkier devices and
PC's.Typical fields of application are:
•Vision-based smart environments.
•Surveillance and tracking applications.
•Applications based on fusion of visual and other sensory data.
•Multi-view vision for Human-Computer Interfaces (HCI).
•3D scene analysis with distributed sensors.
•Distributed multimedia and gaming applications.
•Automated inspection for quality assurance (detection of defects, flaws, missing parts...)
• Non contact measurements.
•Code reading and verification ( barcode,Data Matrix, alphanumericetc.)

CONCLUSION
In contrast to common digital cameras, as known for example for taking holiday pictures, Smart
C a m e r a s a r e e q u i p p e d w i t h a c o m p u t i n g u n i t t h a t i s u s e d f o r t h e

Recent advances in the research field of Computer Vision allow for the detection
of human faces and gestures and for the measurement of distances between objects. In future,
SmartCameras will be able analyse and understand scenes they observe in a cooperative
manner.Distributed Smart Cameras can be connected to each other by ad-hoc or infrastructure
networks
