Visual Effects

With ever increasing quest for real life like imaging systems there seems to
increased interest to add a missing dimension to captured images. Besides
capturing these images there is also a need to develop displays to actually
enjoy depth of a 3D image. With the recent launch of a camera by Fujifilm (FinePix
REAL 3D W1) that is capable of capturing 3D images and video, 3D imaging is no
longer difficult to achieve. Though 3D images are not new, commercial
availability of cost effective cameras, capable of capturing 3D images is a new
concept. Besides capturing 3D images Fujifilm also provides technology for
printing captured images. In this camera, instead of one, two lenses with two
CCDs or sensors are used to capture two images of the same object from different
positions. These images are then processed (imposed on each other along with
other corrections) to create an image that appears to have depth. Besides
capturing images, one also needs to have a setup to view these 3D images; this
can be done either via 3D LCD Monitor available or by using 3D goggles. Fujifilm
has developed a technique to print 3D images with lenticular sheets that create
the 3D effect. Advanced technology encodes and aligns the captured 3D image
according to the pitch of micro lenses arranged in parallel rows on the
lenticular sheet. Seen through the sheet, image data is perceived with a
parallax effect. The result is a natural and beautiful 3D print that preserves
and breathes life into the moment forever. File formats used to store 3D still
image is Multi-Picture format and that for 3D movie is 3D-AVI.

This 3-D photograph has been stitched from multiple photos taken from different angles through a prosumer camera, using 'Anaglyph' software.

Intelligent video surveillance

Success of any video surveillance depends on analysis of footage. To get
best results this analysis should be done real time and that is where
intelligence plays its part. Most of the video surveillance systems used in the
country today are not intelligent, and most require manual monitoring of the
footage which is error prone and at the same time resource consuming. Today
there are advanced video surveillance software available that can carry out
analysis of received footage on the fly. These software are programmed to
recognize suspicious shapes or activity and at the same time notify with an
alarm for the same. This alarm can be in the form of SMS, MMS, email or phone
call. And by just hooking these systems to Internet, one can remotely manage
these systems from anywhere. One big issue plaguing video surveillance systems
is analysis of already stored footage. Intelligent video surveillance comes with
content based search instead of time based and this helps one to reach to a
particular instance in footage without going through large amount of video
footage. If the footage to be searched is too big then one can imagine how
efficient it would be to do a content based search. These systems also come with
the ability to recognize a particular face and raise an alarm. This could be of
great help in securing risk prone areas. Plus, these systems can also be used to
count the number of people and even to click pictures of people entering a
particular venue. Besides face detection reorganization of a particular object
along with its location are also included in intelligent video surveillance
systems. These systems can effectively monitor the region of interest without
depending on light conditions as cameras used are independent of light
conditions and come with a pan-tilt-zoom facility.

Here is a live feed from HEM VIEW camera, which can focus on different regions of interest, plus one gets a 360 degree view of the area in focus.
