Compression of the mammography images using quadtree based energy and pattern blocks
(Işık Üniversitesi, 2017-01-16)
Medical images, like any other digital data, require compression in order to reduce disk space needed for storage and time needed for transmission. This thesis offers , a novel image compression method based on generation ...
Enhancement of the coded speech using filtering
(Işık Üniversitesi, 2017-04-14)
The processing and storage of speech signals are widely implemented in modern communication systems. Decreasing the amount of information for modeling the reconstruction of speech signal enhances the transmission and storage ...
Biometric recognition using bio-signals
(Işık Üniversitesi, 2017-04-14)
The main objective of the project is to increase the recognition rate by establishing a multimodal biometric recognition system that uses two di_erent biometric characteristics, as bio-signals. Today, institutions use ...
Evaluation of feature selection and encoding methods fpr superpixel image parsing
(Işık Üniversitesi, 2017-12-14)
This thesis is about image parsing which is one of the important problems in computer vision. The goal of image parsing is segmentation of object and labeling of each object. Recently, a popular way of image segmentation ...
Data compression for smart grid infrastructure
(Işık Üniversitesi, 2018-01-15)
Embedded systems, which work with large data sets, need larger memory and consume much more data traffc when compared to other IOT (Interne Of Things) devices. In this study, Human's Lossless Compression Algorithm is ...
Automatic speech recognition system for Turkish spoken language
(Işık Üniversitesi, 2012-06-21)
The transmission and storage of speech sounds is possible for decades. In addition by using signal processing techniques, it is also possible tp process speech signals. By using time abd frequency analysis od speech signal ...
Fingertip ECG signal based biometric recognition system
(Işık Üniversitesi, 2016-05-10)
The idea is the; realize biometric recognition system by using ECG signal which was began to use in the last 10 years. Until now, ECG based biometric systems have been developed by using the database which ECG signals are ...
Energy and data cooperation in energy harvesting multiple access channels
(Işık Üniversitesi, 2016)
A typical wireless device is limited by its nite battery, and energy limitation is as a critical bottleneck on wireless network performance. In addition to the EM radiation caused by high power wireless devices, the ...
Compress and forward based cooperation strategies in wireless networks
(Işık Üniversitesi, 2011-09-09)
Cooperative Communications are emerging as an alternative technology to MIMO Communications. In this thesis, we first summarize information theoretical anal- ysis of known channel types and also consider three fundamental ...
Joint modulation and space time block code classification for mimo systems
(Işık Üniversitesi, 2014-10-31)
In this thesis, the problems of modulation classification and space time block code (STBC) classification for MIMO systems are investigated. Two existing MIMO modulation type classification algorithms, an average likelihood ...
