Efficient clustering and quantisation of SIFT features: Exploiting characteristics of the SIFT descriptor and interest region detectors under image inversion

open access: yes, 2011
The SIFT keypoint descriptor is a powerful approach to encoding local image description using edge orientation histograms. Through codebook construction via k-means clustering and quantisation of SIFT features we can achieve image retrieval treating ...

Ultrathin Amphipathic Dual‐Polymer Networks: Unlocking Hyper‐Permeable CO2 Capture via Solvent‐Mediated Poly(Ethylene Oxide) Amorphization

open access: yesAdvanced Functional Materials, EarlyView.
Hydrophilic PEO‐copolymers and hydrophobic PDMS are physically integrated via a compatibilizing solvent into an amphipathic dual‐polymer network with versatile interfacial affinity and completely amorphized PEO segments for hyper‐permeable CO2 transport.

MBR-SIFT: A mirror reflected invariant feature descriptor using a binary representation for image matching. [PDF]

open access: yesPLoS ONE, 2017
The traditional scale invariant feature transform (SIFT) method can extract distinctive features for image matching. However, it is extremely time-consuming in SIFT matching because of the use of the Euclidean distance measure. Recently, many binary SIFT

Defect‐Free Transfer Principles for Scalable, Thin Garnet‐Based Hybrid Solid Electrolytes in Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Defect‐free transfer principles enable scalable fabrication of 15 µm‐thin garnet‐based hybrid solid electrolytes. Hansen solubility parameters correlate interfacial compatibility with coating, transfer, and impregnation behavior, guiding rational selection of slurry/substrate, binder/substrate, and binder/polymer electrolyte combinations.

SIFT-CNN: When Convolutional Neural Networks Meet Dense SIFT Descriptors for Image and Sequence Classification

open access: yesJournal of Imaging, 2022
Despite the success of hand-crafted features in computer visioning for many years, nowadays, this has been replaced by end-to-end learnable features that are extracted from deep convolutional neural networks (CNNs).

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Target classification using SIFT sequence scale invariants

open access: yes, 2012
On the basis of scale invariant feature transform (SIFT) descriptors, a novel kind of local invariants based on SIFT sequence scale (SIFT-SS) is proposed and applied to target classification.

Comparative Analysis of Keypoint Detection Performance in SIFT Implementations on Small-Scale Image Datasets

open access: yesJournal of Innovation Information Technology and Application
Scale-invariant feature transform (SIFT) is widely used as an image local feature extraction method because of its invariance to rotation, scale, and illumination change. SIFT has been implemented in different program libraries.

Hydrophilic Polymers Enable Gastrointestinal Transit Monitoring by Fluorine‐19 Magnetic Resonance Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic fluorinated copolymers dissolve in chyme and give a strong, single 19F signal, unlike phase‐separating perfluorocarbons. Combined 1H‐19F MRI tracks their whole‐gut transit non‐invasively and without ionizing radiation. In rats, the tracers move through the gastrointestinal tract, resist resorption, and are well tolerated, a proof‐of‐concept
