The objective of this research is to develop an ADC stage integrated into ROIC which enables ROIC to have digital output. Digital output method isolates noise caused by outside mediums. At the system level, removal of the ADC proximity card reduces system complexity and volume of the IDDCA system which is important for avionic and missile applications. It also reduces the system cost associated with external ADC components. A digital output ROIC utilizing single slope ADC is fabricated using 0.18 A mu m CMOS technology. ADC has been proven to be functional, and infrared images are sampled with the fabricated ROIC and a LWIR detector. Implemented ADC has 12 bits of resolution supporting 27 kS/s sampling speed. It also has programmable high speed mode that extends readout speed to more than 100 kS/s with 10 bits resolution or 50 kS/s with 11 bits resolution. Power consumption is less than 40 A mu W per column ADC.

Using Active Learning to Allow Activity Recognition on a Large Scale Alemdar, Hande; ERSOY, CEM (2011-11-18) Automated activity recognition systems that use probabilistic models require labeled data sets in training phase for learning the model parameters. The parameters are different for every person and every environment. Therefore, for every person or environment, training is needed to be performed from scratch. Obtaining labeled data requires much effort therefore poses challenges on the large scale deployment of activity recognition systems. Active learning can be a solution to this problem. It is a machine l...
Camera electronics and image enhancement software for infrared detector arrays Küçükkömürler, Alper; Akın, Tayfun; Department of Environmental Engineering (2012) This thesis aims to design and develop camera electronics and image enhancement software for infrared detector arrays. It first discusses the camera electronics suitable for infrared detector arrays, then it concentrates on image enhancement software that are implemented including defective pixel correction, contrast enhancement, noise reduction and pseudo coloring. After that, testing and results of the implemented algorithms were presented. Camera electronics and circuit operation frequency are selected c...
Spatial 3D local descriptors for object recognition in RGB-D images Loğoğlu, K. Berker; Temizel, Alptekin; Kalkan, Sinan; Department of Information Systems (2016) Introduction of the affordable but relatively high resolution color and depth synchronized RGB-D sensors, along with the efforts on open-source point-cloud processing tools boosted research in both computer vision and robotics. One of the key areas which have drawn particular attention is object recognition since it is one of the crucial steps for various applications. In this thesis, two spatially enhanced local 3D descriptors are proposed for object recognition tasks: Histograms of Spatial Concentric Surf...
Modular embedded system design / implementation for mechatronic education and research Nursal, Ali Özgü; Koku, Ahmet Buğra; Department of Mechanical Engineering (2007) In this thesis a modular embedded system for Mechatronics education and research is designed and implemented. Four types of control boards are manufactured and related software is developed at board and PC level. A star like topology is used for boards architecture. One bridge board is responsible for handling communication between the PC and all the other boards that are connected independently to that bridge board. For PC communication Universal Seial Bus (USB), for inter peripheral communication serial p...
Analysis of frequency diverse arrays for radar and communication applications Çetintepe, Çağrı; Demir, Şimşek; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2015) Frequency diverse array (FDA) concept is one particular manifestation of waveform diversity, a topic which gains popularity among the research community in response to pressing demands of modern radar and communication systems such as multiple tasks, capacity and security. Introduction of a set of waveforms to the elements of an array, with slight shifts in the carrier frequencies so to establish frequency diversity, leads to far-field patterns that are remarkably different from conventional phased arrays, ...
