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 ... -
QR-RLS algorithm for error diffusion of color images
(SPIE, 2000)Printing color images on color printers and displaying them on computer monitors requires a significant reduction of physically distinct colors, which causes degradation in image quality. An efficient method to improve the ... -
Restoration of error-diffused images using projection onto convex sets
(2001)In this paper, a novel inverse halftoning method is proposed to restore a continuous tone image from a given half-tone image. A set theoretic formulation is used where three sets are defined using the prior information ... -
Robust adaptive filtering algorithms for α-stable random processes
(Institute of Electrical and Electronics Engineers, 1999-02)A new class of algorithms based on the fractional lower order statistics is proposed for finite-impulse response adaptive filtering in the presence of α-stable processes. It is shown that the normalized least mean p-norm ... -
Sub-band equalization filter design for improving dynamic range performance of modulated wideband converter
(IEEE, 2017)In this work, we propose an iterative method to improve the dynamic range performance of the Modulated Wideband Converter (MWC), which is multi-channel sampling system for digitizing wideband sparse signals below the Nyquist ... -
Theoretical investigation on exact blind channel and input sequence estimation
(IEEE, Piscataway, NJ, United States, 1999)Recent work on fractionally spaced blind equalizers have shown that it is possible to exactly identify the channel and its input sequence from the noise-free channel outputs. However, the obtained results are based on a ...
