An Efficient Method for Narrowband FIR Filter Design
(Revista Computación y Sistemas; Vol. 2 No. 2 y No. 3, 1998-12-15)
Abstract. A new efficient method for implementing narrowband FlR
jilters is presented. The method is based on an lnterpolated
jilter (lFlR) structure and a cascade of comb and integrator
(ClC) structures. The novelty ...
Double Noise Filtering in CT: Pre- and Post-Reconstruction
(Ieee, 2015-01-01)
Motivated by the ALARA (As Low As Reasonably Achievable) principle, this paper proposes to denoise Computed Tomography (CT) images by using a double-filtering approach. First, projection data were filtered using methods ...
Stairway segmentation using Gabor Filter and vanishing point
(08/07/2011)
This paper we are proposing to detect the localization and recognition of an indoor stairway. This is a fundamental step in the implementing of autonomous stair climbing navigation, as well as the implementing of passive ...
EDGE-PRESERVING SPECKLE TEXTURE REMOVAL BY INTERFERENCE-BASED SPECKLE FILTERING FOLLOWED BY ANISOTROPIC DIFFUSION
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Ultrasonography has an inherent noise pattern, called speckle, which is known to hamper object recognition for both humans and computers. Speckle noise is produced by the mutual interference of a set of scattered wavefronts. ...
Speckle Noise Reduction in Ultrasound Imaging using the Key Points in Low Degree Unbiased FIR Filters
(2012-08-31)
In this paper we present a method of reducing speckle noise in applications for ultrasound image processing using low degree unbiased FIR filters.
An important feature of the p-lag gain of unbiased FIR filters is that at ...
