Automatic detection of salient objects and spatial relations in videos for a video database system
(Elsevier BV, 2008-10)Multimedia databases have gained popularity due to rapidly growing quantities of multimedia data and the need to perform efficient indexing, retrieval and analysis of this data. One downside of multimedia databases is the ... -
Çarpıcıdan bağımsız ortak fark matrisi kullanarak video ve görüntü işleme
(IEEE, 2009-04)Bu bildiride gerçel sayılar üzerinde yarı grup kuran yeni bir iletmen tanımlayarak elde edilen bir bölge betimleyicisi ile hareketli obje takibi, yüz sezimi, plaka bulma, bölge betimleme için kullanılabilecek hızlı bir ... -
A fast algorithm for subpixel accuracy image stabilization for digital film and video
(SPIE, 1998)This paper introduces a novel method for subpixel accuracy stabilization of unsteady digital films and video sequences. The proposed method offers a near-closed-form solution to the estimation of the global subpixel ... -
Gibbs random field model based 3-D motion estimation from video sequences
(IEEE, 1994)In contrast to previous global 3D motion concept, a Gibbs random field based method, which models local interactions between motion parameters defined at each point on the object, is proposed. An energy function which gives ... -
A histogram-based approach for object-based query-by-shape-and-color in image and video databases
(Elsevier, 2005)Considering the fact that querying by low-level object features is essential in image and video data, an efficient approach for querying and retrieval by shape and color is proposed. The approach employs three specialized ... -
Impact of scalability in video transmission in promotion-capable differentiated services networks
(IEEE, 2002-09)Transmission of high quality video over the Internet faces many challenges including unpredictable packet loss characteristics of the current Internet and the heterogeneity of receivers in terms of their bandwidth and ... -
Improvement of face detection algorithms for news videos
(IEEE, 2005)People are the most important subjects in news videos and for proper retrieval of person images, face detection is a very crucial step. However, face detection and recognition in news videos is a very challenging task due ... -
Introduction to the issue on emerging techniques in 3-D
(IEEE, 2012)The fifteen papers in this special section that focus on three dimensional content (3D), with particular emphasis on the fusion of conventional camera outputs with those captured by other modalities, such as active sensors, ... -
Iterative technique for 3-D motion estimation in videophone applications
(IEEE, 1994-04)In object based coding of facial images, the accuracy of motion and depth parameter estimates strongly affects the coding efficiency. We propose an improved algorithm based on stochastic relaxation for 3-D motion and depth ... -
Moving object detection using adaptive subband decomposition and fractional lower-order statistics in video sequences
(Elsevier, 2002)In this paper, a moving object detection method in video sequences is described. In the first step, the camera motion is eliminated using motion compensation. An adaptive subband decomposition structure is then used to ... -
Moving shadow detection in video using cepstrum
(SAGE, 2013)Moving shadows constitute problems in various applications such as image segmentation and object tracking. The main cause of these problems is the misclassification of the shadow pixels as target pixels. Therefore, the use ... -
Real time hand gesture recognition for computer interaction
(IEEE, 2014-04)Hand gesture recognition is a natural and intuitive way to interact with the computer, since interactions with the computer can be increased through multidimensional use of hand gestures as compare to other input methods. ... -
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 ... -
A relevance feedback technique for multimodal retrieval of news videos
(IEEE, 2005-11)Content-based retrieval in news video databases has become an important task with the availability of large quantities of data in both public and proprietary archives. We describe a relevance feedback technique that captures ... -
Robust transmission of multi-view video streams using flexible macroblock ordering and systematic LT codes
(IEEE, 2007)The transmission of fully compatible H.264/AVC multi-view video coded streams over packet erasure networks is examined. Macroblock classification into unequally important slice groups is considered using the Flexible ... -
A simple and effective mechanism for stored video streaming with TCP transport and server-side adaptive frame discard
(Elsevier, 2005)Transmission control protocol (TCP) with its well-established congestion control mechanism is the prevailing transport layer protocol for non-real time data in current Internet Protocol (IP) networks. It would be desirable ... -
Tracking motion and intensity variations using hierarchical 2-D mesh modeling for synthetic object transfiguration
(1996-11)We propose a method for tracking the motion and intensity variations of a 2-D mildly deformable image object using a hierarchical 2-D mesh model. The proposed method is applied to synthetic object transfiguration, namely, ... -
