---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Compressive sensing (CS) is a fast growing area of research. It neglects the extravagant acquisition process by measuring lesser values to reconstruct the image or signal. Compressive sensing is adopted successfully in various fields of image proce...

FIRE DETECTION ALGORITHMS USING MULTIMODAL SIGNAL AND IMAGE ANALYSIS Behçet Uğur Töreyin Ph.D. in Electrical and Electronics Engineering Supervisor: Prof. Dr. A. Enis Çetin January, 2009 Dynamic textures are common in natural scenes. Examples of dynamic textures in video include fire, smoke, clouds, volatile organic compound (VOC) plumes in infra-red (IR) videos, trees in the wind, sea and ocea...

The image sensor is the most important part of video and still image processing line in digital video or still camera. Data of CMOS process will produce noise in long transmission distance; therefore it must first be amplified and integrated each pixel data. The choice of medium and apparatus for transmitting image and the other the control signal will be directly related to the quality and rel...

Traditionally, signal processing is considered simply lowlevel processing. In the past decade, however, signal processing has grown to become the area where a variety of tools are created to solve high-level problems that conventionally would be studied by computer vision or machine learning researchers exclusively. For example, multiresolution analysis created popular image features like SIFT ...

We propose an information theoretic model to unify a wide range of existing information theoretic signal processing algorithms in a compact mathematical framework. It is mainly based on stochastic processes, Markov chains and error probabilities. The proposed framework will allow us to discuss revealing analogies and differences between several well known algorithms and to propose interesting e...

Real-time interactive software can be difficult to construct and debug. Aura is a software platform to facilitate highly interactive systems that combine audio signal processing, sophisticated control, sensors, computer animation, video processing, and graphical user interfaces. Moreover, Aura is open-ended, allowing diverse software components to be interconnected in a real-time framework. A r...

This paper describes the architecture of a microwave radar system intended for imaging concealed objects under clothing as a subject walks through the inspection area. The system uses the principle of inverse aperture which is achieved by a person’s movement past a stationary microwave sensor array. In the system, the vertical resolution is achieved by arranging microwave sensors vertically whi...
