Vision Based Automated Cluster Tester

Vision

Based

Automated

Instrument

Cluster

Tester
:

An

automated

machine

vision

system

which

acquires

the

vehicle

cluster

(car

dashboard)

image

using

an

USB

interfaced

webcam
.

The

system

further

processes

the

acquired

image

for

predefined

cluster

configurations

using

computer

vision

algorithms

developed

and

implemented

in

C++
.

The

extracted

cluster

data

(readings)

are

displayed

using

VC++

(MFC)

based

GUI
.

Comparing

the

given

inputs

and

acquired

image

data,

an

instrument

cluster

can

be

tested

from

functional

point

of

view
.

Gesture Recognition using DSTW & DTW

Gesture

Recognition

using

DSTW

and

DTW
:

Scale

and

Translation

invariant

gesture

recognition

based

on

similarity

measure

between

query

and

model

video

sequences

is

implemented
.

Similarity

measure

is

find

out

by

using

either

simple

Dynamic

Time

Warping

(DTW)

or

Advanced

Dynamic

Space

Time

Warping

(DSTW)

algorithm
.

In

presence

of

moving

distractors

motion

and

skin

detection

based

hand

detector

module

may

fail

but

use

of

dynamic

space

time

warping

algorithm

(DSTW)

to

find

the

similarity

measure

improves

accuracy

greatly

over

simple

DTW

algorithm
.

Person Tracker

Person Tracker:
Implemented
motion estimation based person tracker which draws bounding box around
person. The tracker determines center of mass of the person and calculates his/her speed from Euclidean
distance between centers of mass. Furthermore, the tracker determines walking pose of the person such as
Constricted Legs or Expanded Legs.
