Abstract — Infrared vein detection is one of the newest
biomedical techniques researched today. Basic principal
behind this is, when IR light transmitted on palm it passes
through tissue and veins absorbs that light and the vein
appears darker than surrounding tissue. This paper
presents vein detection system using strong IR light source,
webcam, Matlab based image processing algorithm. Using
the Strong IR light source consisting of high intensity led
and webcam camera we captured transillumination image
of palm. Image processing algorithm is used to separate out
the veins from palm.
make it difficult to locate veins and administer life
saving drugs or solutions. In such cases it becomes very
necessary to have a device that detects the exact location
of required vein. Also in case of blood transfusion,
blood donation, blood with draw, etc. it is necessary to
know the exact position of the veins. Even trained
nurses and doctors many times find it difficult to exactly
locate the blood veins, on the first attempt, especially for
obese people. In various medical situations, the exact
location of veins needs to be identified. The other

I. INTRODUCTION
A huge progress is made in the field of biomedical
imaging technologies but they have generally resulted in
high product costs. Another major concern is the
portability factor. We have addressed these two major
concerns in this device to a maximum extent. As
compared to infrared imaging, significant amount of
work is done in other areas of imaging techniques. The
use of infrared imaging technique is a relatively less
explored area but promises to deliver high-end results at
low development costs. The major clinical problem
faced by the physicians is difficulty in accessing veins
for intra-venous drug delivery and other purposes. It is
also noted that improper location of veins is a cause for
delay in several medical treatments. It is relevant in case
of paediatrics, obese, dark toned people and also in adult
patients. Unnecessary puncturing of veins is done by the
physicians because the visibility of veins is not clear.
Therefore this causes various problems to the patients
and especially in children and aged. The results are
swelling, irritation, bleeding and blackening of the skin.
Although a significant amount of work has been done in
this area and devices like Accurate Vein Viewer have
come up, but the major problem lies in their cost and
portability factor.
Intravenous injections: For giving medicines and drugs
to the patients, intra- venous injections are given by
doctors and nurses.
Bruises and Bums: In case of vein diseases like Deep
Vein Thrombosis and Varicose Veins, bruises appear on
the skin, therefore for the treatment of these diseases,
detection of veins is highly essential. Accidents
involving first or second degree of bums cause the
scarring of the skin. Here appearance of the skin
becomes deterred causing the skin to appear whiter or in
certain cases darker. The determinations of veins
become tough in such cases as well.
Blood transfusions: It is a process in which blood is
given to the person intravenously. Blood donation,
kidney dialysis also need perfect vein detection
Among children: Locating veins in young children and
infants may be especially difficult and having to
puncture them several times with a needle is very
frightful and agonizing for the child.
Geriatrics: Many elderly people often require numerous
blood tests or medicinal injections and an efficient
means of puncture would reduce excessive bruise and
enhance the patients overall comfort level.
The wrong administration of intra-venous injections will
lead to several problems like swelling of the skin,
appearance of rashes ,damage to bones and nerves,
When the doctors are treating trauma patients, every
c10tting of blood allergies reactions ,appearance of
second counts. Bruises, bums and other physical injuries
black spots , darkening of veins due to peripheral venous

B. Near infrared imaging
Human eyes can only detect visible light that occupies a
very narrow band (400 - 700nm) of the entire
electromagnetic spectrum. However, there is much more
information contained in other bands of the
electromagnetic spectrum rejected by the objects of
interest. For human vein patterns on the periphery, the
visibility under normal visible light conditions is very
low. However, this can be resolved by using NearInfrared imaging techniques. The special attributes of
Near-Infrared imaging which makes it suitable for vein
detection are:
1.
NIR can penetrate into the biological tissue up to
3mm of depth.
2.
The reduced haemoglobin in venous blood absorbs
more of this infrared radiation than the surrounding
tissue.
Therefore, by exposing desired body part with the
infrared radiation of specific wavelength, the vein image
can be captured by an IR camera In the resulting image,
the veins appear darker than the surrounding tissue,
biologically; there is a me die al spectral window which
extends approximately from about 700 to 900 nm, where
light in this spectral window penetrates deeply into
tissues, thus allowing non-invasive investigation.
The infrared radiation is absorbed in a different
wavelength in various types of tissues. In order to
achieve visual penetration through the respective tissue,
lighting should be performed under a very tight optical
window, namely 740 nm up to 960 nm (inside the near
infrared part of the electromagnetic radiation
spectrum).Hence in this device near infrared technique
is chosen rightly to view the veins.
II.LITERATURE ON RELATED WORKS
Vein detection is one of the latest biomedical techniques
researched today. While the concept behind the method
is simple, there are various challenges to be found
throughout the design and implementation of a device
concerning the lighting system and the image processing
algorithms at a very low price. While a very few devices
based on the infrared
technique have been implemented, there still exists a
strong need to develop such medical devices.

low-leak light source, near-infrared CMOS camera and a
small and light one-eye head mounted display. Using the
developed
system,
they

obtain
the
transillumination images in all part of the adult forearm
with as much as 67 mm They can obtain a clearer
transillumination image of deep-seated blood vessels, it
can be used to assist the intravenous injection, the
varicose-vein treatment, arterial catheterization,
intraoperative observation of blood vessels and lymph
ducts, and so on.

Imran Badshah,[2] Mohammed Saleem gives system is
composed of a modified wed camera with a long-pass, a
NIR ring of LEDs is used for illuminating the desired
body part with infrared light. The LED ring has a circuit
driver and the power is provided from the laptop itself
through a USB cable. The software used for processing
is Computer Vision(OpenCV) on Ubuntu. It is an open
source computer vision library which is originally
developed. The library is written in C and C++ and runs
under Linux, Windows and MacOS X.
Deepak Prasanna.R a*, Neelamegam.P a, Sriram.S b,
Nagarajan Raju[3] they explains various enhancement
techniques such as image negative, gray level slicing,
histogram equalization, contrast stretching, laplacian
sharpening, unsharp masking, high boost filtering, and
histogram equalization of high boost filter. These
techniques are applied on the hand image using
(OpenCV) open source computer vision library
developed by Intel. A comparative study of all these
enhancement techniques is carried out to find the best
technique to enhance hand vein pattern. The result
shows the histogram equalization of high boost filtering
technique provides better enhancement of vein pattern.

network mesh. The acquired image is then processed
and optimized using Matlab software to Emphasize
areas of interest and to Eliminate unnecessary
information. The project Also includes a stage in Which

To achieve low scanning errors, the acquired image
should be almost noiseless and the algorithms should
detect the vein pattern in various conditions. Many
implementations of this method are now in a
commercial phase and there is a great need for low cost
systems that can detect human veins with minimum
computational requirements.
We take the guidance of doctors and find the dorsal

Global Thershoding:-The simplest property that pixels
in a region can share is intensity. So, a natural way to
segment such regions is through Thershoding, the
separation of light and dark regions. Thershoding creates
binary images from grey-level one by one turning all
pixels below some threshold to zero and all pixels about
that threshold to one. If g(x, y) is a threshold version of
f(x, y) at some global threshold T,

Adaptive Thershoding:- In this particular case adaptive
Thershoding will be used to generate binary image of

for veins and bright (1’s) background. This obtained
binary image is display on computer
Display is used for display image final image on

between vein and background
Morphological operation is used to remove unwanted

Then we select connected component having large area
that is large area component in an image. That is longest
area component in an image. The resultant image is
shown in fig 8. In that image veins appear in white colour
and other part are black

colour.

V.CONCLUSION:-
Fig. 5 result of adaptive threshold
After adaptive thresholding we apply image negative
operation to turn white lines to black that lines are veins.
To realize the vein detection system, we have developed
a Simultaneous observation system for a body surface
image and a transillumination image of blood vessels.
The system Basically consists of a light source, a
camera, a personal Computer. As a light source, many
LED’s were arranged on a printed circuit board. It made
the high-intensity and small-leak illumination possible.
Using the developed system, the blood veins in palm
hands were visualized. We could obtain the
transillumination images of the palm hand and using
image processing algorithm we extract veins from palm.

To realize the vein detection system, we have developed
a Simultaneous observation system for a body surface
image and a transillumination image of blood vessels.
The system Basically consists of a light source, a
camera, a personal Computer. As a light source, many
LED’s were arranged on a printed circuit board. It made
the high-intensity and small-leak illumination possible.
Using the developed system, the blood veins in palm
hands were visualized. We could obtain the
transillumination images of the palm hand and using
image processing algorithm we extract veins from palm.
