Rotation invariant matching of partial shoeprints [PDF]
, 2009 In this paper, we propose a solution for the problem of rotated partial shoeprint retrieval, based on the combined use of local points of interest and SIFT descriptor. Once the generated features are encoded using SIFT descriptor, matching is carried out

Feature matching algorithm based on partial limitation search region
Dianzi Jishu Yingyong, 2018 This paper proposes a feature matching algorithm for partial limitation search regions, which combines spatial constraints with local descriptors. Based on the ASIFT algorithm, this paper improves the defects of directly removing one-to-many and many-to ...

Reliable features matching for humanoid robots [PDF]
2007 7th IEEE-RAS International Conference on Humanoid Robots, 2007 This paper describes a visual feature detector and descriptor scheme designed to address the specific problems of humanoid robots in the tasks of visual odometry, localization, and SLAM (Simultaneous Localization And Mapping). During walking, turning, and squatting movements, the camera of a humanoid robot moves in jerky and sometimes unpredictable way.

MaskFlownet: Asymmetric Feature Matching With Learnable Occlusion Mask [PDF]
Computer Vision and Pattern Recognition, 2020 Feature warping is a core technique in optical flow estimation; however, the ambiguity caused by occluded areas during warping is a major problem that remains unsolved.

STV-based Video Feature Processing for Action Recognition
, 2012 In comparison to still image-based processes, video features can provide rich and intuitive information about dynamic events occurred over a period of time, such as human actions, crowd behaviours, and other subject pattern changes.

Feature instructions improve face-matching accuracy. [PDF]
PLoS ONE, 2018 Identity comparisons of photographs of unfamiliar faces are prone to error but important for applied settings, such as person identification at passport control.

Pattern Matching for Building Feature Extraction [PDF]
IEEE Geoscience and Remote Sensing Letters, 2014 We address the problem of detecting building dominant scatterers using a reduced number of measurements with applications to through-the-wall radar (TWR) and urban sensing. We consider oblique illumination, which specially enhances the radar returns from the corners formed by the orthogonal intersection of two walls.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...

Towards Adversarial Robustness via Feature Matching
IEEE Access, 2020 Image classification systems are known to be vulnerable to adversarial attacks, which are imperceptibly perturbed but lead to spectacularly disgraceful classification.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.
