Computational image speckle suppression using block matching and machine learning.
Applied Optics, 2019We develop an image despeckling method that combines nonlocal self-similarity filters with machine learning, which makes use of convolutional neural network (CNN) denoisers.

IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
Detection of moving objects in a video sequence is a growing field, used in various domains. There are, in the literature, several approaches to detect such movements. In this paper, we will focus on one of these approaches namely block matching. We propose to speed the performances of the block matching algorithm using the Bees' Algorithm which is ...

Two-Level Block Matching Pursuit for Polarimetric Through-Wall Radar Imaging
IEEE Transactions on Geoscience and Remote Sensing, 2018In this paper, we propose a two-level block matching pursuit (TLBMP) algorithm based on a probabilistic graph model for polarimetric through-wall radar imaging (TWRI).

Reconstruction of the block matching profiles
Human Immunology, 1999Block matching is a valuable tool for selecting donors for bone marrow transplantation. Identical, electrophoretic profiles of unrelated bone marrow donor-recipient pairs have been shown to be associated with long-term survival and a reduction of graft versus host disease (GVHD).

Block matching along epipolar lines is the core of most stereovision algorithms in geographic information systems. The usual distances between blocks are the sum of squared distances in the block (SSD) or the correlation. Minimizing these distances causes the fattening effect, by which the center of the block inherits the disparity of the more ...

A denoising framework for microseismic and reflection seismic data based on block matching
Geophysics, 2018Microseismic and seismic data with a low signal-to-noise ratio affect the accuracy and reliability of processing results and their subsequent interpretation. Thus, denoising is of great importance.

Fast Hash-Based Inter-Block Matching for Screen Content Coding
IEEE transactions on circuits and systems for video technology (Print), 2018In the latest High Efficiency Video Coding (HEVC) development, i.e., HEVC screen content coding extensions (HEVC-SCC), a hash-based inter-motion search/block matching scheme is adopted in the reference test model, which brings significant coding gains to

(Un)stable matchings with blocking costs
Operations Research Letters, 2021Abstract We introduce and study weighted bipartite matching problems under strict preferences where blocking edges can be paid for, thus imposing costs rather than constraints as in classical models. We focus on the setting in which the weight of an edge represents the benefit from including it in the matching and/or the cost if it is a blocking edge.
