Automatic Parallelization of Full 2-D Block Matching for Real Time Motion Compensation and Mapping into Special Purpose Architectures

open access: yes, 2008
The most important issue in video encoding is motion compensation within a frame sequence. Block matching techniques are used by various algorithms [5], [6] to estimate the motion into succesive frames.

Fully Polarimetric SAR Image Filtering by Combining Block Matching and Lee Filter

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Speckle filtering is a key preprocessing approach for the applications of polarimetric synthetic aperture radar (PolSAR) data. Most current PolSAR filtering algorithms can hardly get good balance in suppressing speckle and retaining image details.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Set ubal, Portugal, Volume 2, pp. 359--363 1 STRATEGIES FOR FAST TRUE MOTION

open access: yes, 2006
Block matching is a widely used method for fast motion estimation. Although using a very simple motion model, which does not fit most real world video material, many motion compensating video compression algorithms use block matching because of its speed.

Dense Stereo Correspondence Using Polychromatic Block Matching

open access: yes, 1993
. Only few problems in computer vision have been investigated more vigorously than stereo. Nevertheless, almost all methods use only gray values and most of them are feature-based techniques, i.e., they produce only sparse depth maps. This paper presents

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Fast block matching using prediction and rejection criteria

open access: yes, 2013
In this paper, we present a fast block matching algorithm by making use of the correlation between layers of the sum pyramid for a block. To speed our method, an algorithm is also developed to predict the initial motion vector for a template block. Using
