Automatic radar antenna scan analysis in electronic warfare
(Bilkent University, 2010)Estimation of the radar antenna scan period and recognition of the antenna scan type is usually performed by human operators in the Electronic Warfare (EW) world. In this thesis, we propose a robust algorithm to automatize ... -
Detection and evaluation of physical therapy exercises by dynamic time warping using wearable motion sensor units
(Springer Verlag, 2014)We develop an autonomous system that detects and evaluates physical therapy exercises using wearable motion sensors. We propose an algorithm that detects all the occurrences of one or more template signals (representing ... -
Detection and evaluation of physical therapy exercises from wearable motion sensor signals by dynamic time warping
(IEEE Computer Society, 2014)We develop an autonomous system to detect and evaluate physical therapy exercises using wearable motion sensor units. We propose an algorithm based on the dynamic time warping (DTW) dissimilarity measure to detect the ... -
Human activity classification with miniature inertial sensors
(Bilkent University, 2009)This thesis provides a comparative study on activity recognition using miniature inertial sensors (gyroscopes and accelerometers) and magnetometers worn on the human body. The classification methods used and compared in ... -
Intelligent sensing for robot mapping and simultaneous human localization and activity recognition
(Bilkent University, 2011)We consider three different problems in two different sensing domains, namely ultrasonic sensing and inertial sensing. Since the applications considered in each domain are inherently different, this thesis is composed ... -
Novel methods for microscopic image processing, analysis, classification and compression
(Bilkent University, 2013)Microscopic images are frequently used in medicine and molecular biology. Many interesting image processing problems arise after the initial data acquisition step, since image modalities are manifold. In this thesis, we ... -
On a parameter estimation method for Gibbs-Markov random fields
(IEEE, 1994)This correspondence is about a Gibbs-Markov random field (GMRF) parameter estimation technique proposed by Derin and Elliott. We will refer to this technique as the histogramming (H) method. First, the relation of the H ... -
Recognition and classification of human activities using wearable sensors
(Bilkent University, 2012)We address the problem of detecting and classifying human activities using two different types of wearable sensors. In the first part of the thesis, a comparative study on the different techniques of classifying human ... -
Vision based handwritten character recognition
(Bilkent University, 2003)Online automatic recognition of handwritten text has been an ongoing research problem for four decades. It is used in automated postal address and ZIP code and form reading, data acquisition in bank checks, processing ...
