Interference mitigation effects on synthetic aperture radar coherent data products
(2015-07)
Both radio frequency interference from sources external to the synthetic aperture radar system and techniques to mitigate radio frequency interference can degrade the quality of the image products. Often it is the second ...
Hybrid machine learning approaches for scene understanding: From segmentation and recognition to image parsing
(2017-05)
We alleviate the problem of semantic scene understanding by studies on object segmentation/recognition and scene labeling methods respectively. We propose new techniques for joint recognition, segmentation and pose estimation ...
Efficient schemes to size transistors for optimal delay by solving fanout branches with balancing algorithm
(2015-05)
High performance digital system requires minimal logic and properly sized transistor to operate in all PVT corners. Specifically, high-speed data-path design is mostly about optimizing the system for better timing. In this ...
Sparse signal recovery and detection utilizing side information
(2017-10)
In this dissertation, we investigate the signal recovery and detection task for compressive sensing and wireless spectrum sensing. First, we investigate the compressive sensing task for the difference frames of videos. ...
Improved IPTV channel change times through multicast caching of pre-selected channels
(2014-12)
IPTV has grown in recent years to an estimated 100 million users worldwide. IPTV uses IGMP processes to stream an individual channel to a user until the next channel change when the current channel is stopped and the new ...
Visual masking in natural scenes: Database, models, and an application to perceptual image coding
(2015-05)
Studies of visual masking have provided a wide range of important insights into the processes involved in visual coding. However, very few of these studies have employed natural scenes as masks, and little is known on how ...
Cooperative control, learning and sensing in mobile sensor networks
(2011-12)
Scope and Method of Study:
Study of Smart Integrated Renewable Energy Systems (SIRES)
(2017-09)
Energy availability is a severe problem in majority of the remote rural areas of the world. Development of energy-resources-poor rural areas has been discussed by many in the past. Rural electrification was the first major ...
Measurement and analysis of natural video masked dynamic discrete cosine transform noise detectability
(2015-05)
Lossy video compression lowers fidelity and can leave visual artifacts. Current video compression algorithms are guided by quality assessment tools designed around subjective data based on aggressive video compression. ...
Front end of a 900MHz RFID for biological sensing
(2015-12)
This thesis presents the front end of a 900MHz passive RFID for biological sensing. The components blocks of the front end consist of power harvester, switch capacitor voltage regulator, phase lock loop and a modulator and ...
