Image denoising using adaptive subband decomposition
(IEEE, 2001)In this paper, we present a new image denoising method based on adaptive subband decomposition (or adaptive wavelet transform) in which the filter coefficients are updated according to an Least Mean Square (LMS) type ... -
Image sequence analysis for emerging interactive multimedia services-the European COST 211 framework
(Institute of Electrical and Electronics Engineers, 1998-11)Flexibility and efficiency of coding, content extraction, and content-based search are key research topics in the field of interactive multimedia. Ongoing ISO MPEG-4 and MPEG-7 activities are targeting standardization to ... -
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 ... -
Influence function based Gaussianity tests for detection of microcalcifications in mammogram images
(IEEE, 1999-10)In this paper, computer-aided diagnosis of microcalcifications in mammogram images is considered. Microcalcification clusters are an early sign of breast cancer. Microcalcifications appear as single bright spots in mammogram ... -
Influence of cigarette smoking on white matter in patients with clinically isolated syndrome as detected by diffusion tensor imaging
(Turkish Society of Radiology, 2016)PURPOSE Cigarette smoking has been associated with increased occurrence of multiple sclerosis (MS), as well as clinical disability and disease progression in MS. We aimed to assess the effects of smoking on the white matter ... -
Interactive training of advanced classifiers for mining remote sensing image archives
(ACM, 2004)Advances in satellite technology and availability of down-loaded images constantly increase the sizes of remote sensing image archives. Automatic content extraction, classification and content-based retrieval have become ... -
Intravascular MR-monitored balloon angioplasty: An in vivo feasibility study
(Elsevier Inc., 1998)PURPOSE: To develop a new method for monitoring balloon angioplasty by using an intravascular magnetic resonance (MR) imaging technique. MATERIALS AND METHODS: Nine New Zealand White rabbits were used: seven for technique ... -
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 ... -
İstatistiksel örüntü tanıma teknikleri kullanarak kızılberisi algılayıcılarla hedef ayırdetme
(IEEE, 2006-04)This study compares the performances of different statistical pattern recognition techniques to differentiation of commonly encountered features or targets in indoor environments, such as planes, corners, edges, and ... -
Learning bayesian classifiers for scene classification with a visual grammar
(IEEE, 2005)A challenging problem in image content extraction and classification is building a system that automatically learns high-level semantic interpretations of images. We describe a Bayesian framework for a visual grammar that ... -
Morphological subband decomposition structure using GF(N) arithmetic
(IEEE, 1996-09)Linear filter banks with critical subsampling and perfect reconstruction (PR) property have received much interest and found numerous applications in signal and image processing. Recently, nonlinear filter bank structures ... -
Moving region detection in wavelet compressed video
(IEEE, 2004)In many vision based surveillance systems the video is stored in wavelet compressed form. In this study, an algorithm for moving object and region detection in video that is compressed using a wavelet transform (WT) is ... -
MPEG-7 uyumlu video veri tabanlari için önemli nesnelerin otomatik olarak bulunmasi
(IEEE, 2008-04)Bu çalışma, genel olarak nesneye dayalı endekslemeyi destekleyen, özel olarak MPEG-7 uyumlu veritabanları için, videolardan önemli nesnelerin otomatik olarak çıkarılmasını saglayabilecek bir yöntem sunmaktadır. Şimdiye ... -
A multiresolution nonrectangular wavelet representation for two-dimensional signals
(Elsevier, 1993)In this paper, a new multiresolution wavelet representation for two-dimensional signals is described. This wavelet representation is based on a nonrectangular decomposition of the frequency domain. The decomposition can ... -
A novel hierarchical coding scheme based on polar mass distribution
(IEEE, 1994)A novel method for coding arbitrarily shaped binary objects is presented. The main idea is expressing the binary object in terms of radial closed curves, that is, closed curves for which radius versus angle is a function. ... -
Object-oriented texture analysis for the unsupervised segmentation of biopsy images for cancer detection
(Elsevier BV, 2009-06)Staining methods routinely used in pathology lead to similar color distributions in the biologically different regions of histopathological images. This causes problems in image segmentation for the quantitative analysis ... -
On a parameter estimation method for Gibbs-Markov random fields
(IEEE, 1994)This correspondence is about a Gibbs-Markov random field (GMRF) parameter estimation technique proposed by Derin and Elliott. We will refer to this technique as the histogramming (H) method. First, the relation of the H ... -
Perception of 3-D Surfaces from 2-D Contours
(1993)Inference of 3-D shape from 2-D contours in a single image is an important problem in machine vision. We survey classes of techniques proposed in the past and provide a critical analysis. We propose that two kinds of ... -
Plasmonics: merging photonics and electronics at nanoscale dimensions
((AAAS) American Association for the Advancement of Science, 2006)Electronic circuits provide us with the ability to control the transport and storage of electrons. However, the performance of electronic circuits is now becoming rather limited when digital information needs to be sent ... -
QR-RLS algorithm for error diffusion of color images
