ManiDec: Manifold Constrained Low-Rank and Sparse Decomposition

open access: yesIEEE Access, 2019
Low-rank and sparse decomposition based image alignment has recently become an important research topic in the computer vision community. However, the reconstruction process often suffers from the perturbations caused by variations of the input samples ...

PANet: Few-Shot Image Semantic Segmentation With Prototype Alignment [PDF]

open access: yesIEEE International Conference on Computer Vision, 2019
Despite the great progress made by deep CNNs in image semantic segmentation, they typically require a large number of densely-annotated images for training and are difficult to generalize to unseen object categories.

Hinode Calibration for Precise Image Co-alignment between SOT and XRT (November 2006 -- April 2007)

open access: yes, 2007
To understand the physical mechanisms for activity and heating in the solar atmosphere, the magnetic coupling from the photosphere to the corona is an important piece of information from the Hinode observations, and therefore precise positional alignment

Human-Object Interaction Detection via Weak Supervision [PDF]

open access: yesarXiv, 2021
The goal of this paper is Human-object Interaction (HO-I) detection. HO-I detection aims to find interacting human-objects regions and classify their interaction from an image. Researchers obtain significant improvement in recent years by relying on strong HO-I alignment supervision from [5].

Registration and Fusion of Multi-Spectral Images Using a Novel Edge Descriptor

open access: yes, 2018
In this paper we introduce a fully end-to-end approach for multi-spectral image registration and fusion. Our method for fusion combines images from different spectral channels into a single fused image by different approaches for low and high frequency ...

A Technique for Photometric Detection and Measurement of Unresolved Binary Systems [PDF]

open access: yes, 1997
A technique is described for the detection and measurement of close binary systems whose images are unresolved. The method is based on analysis of the moment of inertia tensor of the image, from which the product of the binary flux ratio and square of ...

Alignment-Enriched Tuning for Patch-Level Pre-trained Document Image Models [PDF]

open access: yesarXiv, 2022
Alignment between image and text has shown promising improvements on patch-level pre-trained document image models. However, investigating more effective or finer-grained alignment techniques during pre-training requires a large amount of computation cost and time. Thus, a question naturally arises: Could we fine-tune the pre-trained models adaptive to

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Improved image processing for 3D virtual object construction from serial sections reveals tissue patterns in root tips of Zea mays

open access: yesApplications in Plant Sciences, 2023
Premise Previously we described methods for generating three‐dimensional (3D) virtual reconstructions of plant tissues from transverse thin sections. Here, we report the applicability of longitudinal sections and improved image‐processing steps that are ...
