Content-based retrieval of historical Ottoman documents stored as textual images
(IEEE, 2004)
There is an accelerating demand to access the visual content of documents stored in historical and cultural archives. Availability of electronic imaging tools and effective image processing techniques makes it feasible to ...
Stereoscopic view-dependent visualization of terrain height fields
(IEEE, 2002)
Visualization of large geometric environments has always been an important problem of computer graphics. In this paper, we present a framework for the stereoscopic view-dependent visualization of large scale terrain models. ...
PHR: A parallel hierarchical radiosity system with dynamic load balancing
(Springer, 2005)
In this paper, we present a parallel system called PHR for computing hierarchical radiosity solutions of complex scenes. The system is targeted for multi-processor architectures with distributed memory. The system evaluates ...
Right-triangular subdivision for texture mapping ray-traced objects
(Springer, 1998)
The introduction of global illumination and texture mapping enabled the generation of high-quality, realistic looking images of computer graphics models. We describe a fast and efficient 2D texture mapping algorithm that ...
A rule-based video database system architecture
(Elsevier, 2002)
We propose a novel architecture for a video database system incorporating both spatio-temporal and semantic (keyword, event/activity and category-based) query facilities. The originality of our approach stems from the fact ...
Flexible test-bed for unusual behavior detection
(ACM, 2007-07)
Visual surveillance and activity analysis is an active research field of computer vision. As a result, there are several different algorithms produced for this purpose. To obtain more robust systems it is desirable to ...
Extraction of 3D navigation space in virtual urban environments
(IEEE, 2005-09)
Urban scenes are one class of complex geometrical environments in computer graphics. In order to develop navigation systems for urban sceneries, extraction and cellulization of navigation space is one of the most commonly ...
Nonrectangular wavelets for multiresolution mesh analysis and compression
(IEEE, 2006)
We propose a new Set Partitioning In Hierarchical Trees (SPIHT) based mesh compression framework. The 3D mesh is first transformed to 2D images on a regular grid structure. Then, this image-like representation is wavelet ...
Keyframe labeling technique for surveillance event classification
(S P I E - International Society for Optical Engineering, 2010)
The huge amount of video data generated by surveillance systems necessitates the use of automatic tools for their efficient analysis, indexing, and retrieval. Automated access to the semantic content of surveillance videos ...
Real-time fire and flame detection in video
(IEEE, 2005)
This paper proposes a novel method to detect fire and/or flame by processing the video data generated by an ordinary camera monitoring a scene. In addition to ordinary motion and color clues, flame and fire flicker is ...
