Detection of microcalcifications in mammograms using nonlinear subband decomposition and outlier labeling
(SPIE, 1997-02)Computer-aided diagnosis will be an important feature of the next generation picture archiving and communication systems. In this paper, computer-aided detection of microcalcifications in mammograms using a nonlinear subband ... -
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 ... -
Key frame selection from MPEG video data
(SPIE, 1997-02)This paper describes a method for selecting key frames by using a number of parameters extracted from the MPEG video stream. The parameters are directly extracted from the compressed video stream without decompression. A ... -
Mean-shift tracking of moving objects using multi-dimensional histograms
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2004-04)In this paper, a moving object tracking algorithm for infrared image sequences is presented. The tracking algorithm is based on the mean-shift tracking method which is based on comparing the histograms of moving objects ... -
Moving object detection in video by detecting non-Gaussian regions in subbands and active contours
(IEEE, 2003-09)A multi-stage moving object detection algorithm in video is described in this paper. First, the camera motion is eliminated by motion compensation. An adaptive subband decomposition structure is then used to analyze the ... -
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 ... -
A particle swarm optimization based SAR motion compensation algorithm for target image reconstruction
(IEEE, 2010)A new SAR motion compensation algorithm is proposed for robust reconstruction of target images even under large deviations of the platform from intended flight path. Phase error due to flight path deviations is estimated ... -
SAR image reconstruction by expectation maximization based matching pursuit
(Academic Press, 2015)Synthetic Aperture Radar (SAR) provides high resolution images of terrain and target reflectivity. SAR systems are indispensable in many remote sensing applications. Phase errors due to uncompensated platform motion degrade ... -
Segmentation-based extraction of important objects from video for object-based indexing
(IEEE, 2008-06)We describe a method to automatically extract important video objects for object-based indexing. Most of the existing salient object detection approaches detect visually conspicuous structures in images, while our method ... -
Small moving object detection in video sequences
(IEEE, 2000-06)In this paper, we propose a method for detection of small moving objects in video. We first eliminate the camera motion using motion compensation. We then use an adaptive predictor to estimate the current pixel using ... -
Small moving object detection using adaptive subband decomposition and fractional lower order statistics in video sequences
(2001-07-08)In this paper, a small moving object method 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 ... -
Three-dimensional motion and dense-structure estimation using convex projections
(SPIE, 1997-02)We propose a novel method for estimating the 3D motion and dense structure of an object form its two 2D images. The proposed method is an iterative algorithm based on the theory of projections onto convex sets (POCS) that ...
