In recent years, the utilization of 3D display systems became popular in many application areas. One of the most important issues in the utilization of these systems is to render the correct view to the observer based on his/her position. In this thesis, we propose and implement a single user view rendering system for autostereoscopic/stereoscopic displays. The system can easily be installed on a standard PC together with an autostereoscopic display or stereoscopic glasses (shutter, polarized, pulfrich, and anaglyph) with appropriate video card. Proposed system composes of three main blocks: view point detection, view point tracking and intermediate view reconstruction. Haar object detection method, which is based on boosted cascade of simple feature classifiers, is utilized as the view point detection method. After detection, feature points are found on the detected region and accordingly they are fed to the feature tracker. View point of the observer is calculated by using the tracked position of the observer on the image. Correct stereoscopic view is, then, rendered on the display. A 3D warping-based method is utilized in the system as the intermediate view reconstruction method. System is implemented on a computer with Pentium IV 3.0 GHz processor using E-D 3D shutter glasses and Creative NX Webcam.

Texture mapping by multi-image blending for 3D face models Bayar, Hakan; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2007) Computer interfaces has changed to 3D graphics environments due to its high number of applications ranging from scientific importance to entertainment. To enhance the realism of the 3D models, an established rendering technique, texture mapping, is used. In computer vision, a way to generate this texture is to combine extracted parts of multiple images of real objects and it is the topic studied in this thesis. While the 3D face model is obtained by using 3D scanner, the texture to cover the model is constr...
Data parallelism for ray casting large scenes on a cpu-gpu cluster Topcu, Tümer; İşler, Veysi; Department of Computer Engineering (2008) In the last decade, computational power, memory bandwidth and programmability capabilities of graphics processing units (GPU) have rapidly evolved. Therefore, many researches have been performed to use GPUs in advanced graphics rendering. Because of its high degree of parallelism, ray tracing has been one of the rst algorithms studied on GPUs. However, the rendering of large scenes with ray tracing can easily exceed the GPU's memory capacity. The algorithm proposed in this work uses a data parallel approac...
SystemC implementation with analog mixed signal modeling for a microcontroller Mert, Yakup Murat; Aşkar, Murat; Department of Electrical and Electronics Engineering (2007) In this thesis, an 8-bit microcontroller, PIC 16F871, has been implemented using SystemC with classical hardware design methods. Analog modules of the microcontroller have been modeled behaviorally with SystemC-AMS which is the analog and mixed signal extensions for the SystemC. SystemC-AMS provides the capability to model non-digital modules and synchronization with the SystemC kernel. In this manner, electronic systems that have both digital and analog components can be described and simulated very effect...
3D face reconstruction using stereo images and structured light Öztürk, Ahmet Oğuz; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2007) Nowadays, 3D modelling of objects from multiple images is a topic that has gained great recognition and is widely used in various fields. Recently, lots of progress has been made in identification of people using 3D face models, which are usually reconstructed from multiple face images. In this thesis, a system including stereo cameras and structured light is built for the purpose of 3D modelling. The system outputs are 3D shapes of the face and also the texture information registered to this shape. Althoug...
Efficient calibration of a multi-camera measurement system using a target with known dynamics Aykın, Murat Deniz; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2008) Multi camera measurement systems are widely used to extract information about the 3D configuration or “state” of one or more real world objects. Camera calibration is the process of pre-determining all the remaining optical and geometric parameters of the measurement system which are either static or slowly varying. For a single camera, this consist of the internal parameters of the camera device optics and construction while for a multiple camera system, it also includes the geometric positioning of the in...
