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. [Used: VC++ (MFC), MATLAB]
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.[Language Used: MATLAB]

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. [Language Used: MATLAB]
