Image matching via progressive priors

open access: yesElectronics Letters, 2022
It is a fundamental and challenging issue how to improve the accuracy of image matching in computer vision. To address this issue, an image matching method is proposed, which is via progressive priors of a putative dataset.

Joint Image Deblurring and Matching with Blurred Invariant-Based Sparse Representation Prior

open access: yesComplexity, 2019
Image matching is important for vision-based navigation. However, most image matching approaches do not consider the degradation of the real world, such as image blur; thus, the performance of image matching often decreases greatly. Recent methods try to

A LANDMARK MATCHING ALGORITHM FOR THE GEOSTATIONARY SATELLITE IMAGES BASED ON MULTI-LEVEL GRIDS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
The resolution of geostationary satellite image is not high and the image is covered with clouds. At present, when the extracted feature points are unstable, there are some problems, such as low matching accuracy or even matching failure.

Distinctiveness maps for image matching [PDF]

open access: yesProceedings 10th International Conference on Image Analysis and Processing, 2003
Stereo correspondence is hard because different image features can look alike. We propose a measure for the ambiguity of image points that allows matching of distinctive points first and breaks down the matching task into smaller and separate subproblems.

Camera focusing based on fringe pattern matching [PDF]

open access: yes, 1997
A method of camera focusing based on fringe pattern matching is presented. In the method, the variance of the mismatch function is used as a focus measure.

Outlier modeling in image matching [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2003
We address the question of how to characterize the outliers that may appear when matching two views of the same scene. The match is performed by comparing the difference of the two views at a pixel level aiming at a better registration of the images.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Performance Enhancement Step for Motion Estimation via Feature-based Image Matching [PDF]

open access: yes, 2022
Most of the complicated and sophisticated tasks in visual robotics applications usually build upon the image matching step as matching images of the same scene can provide important information (e.g., camera motion).
