Transitions of a multi-scale image hierarchy tree
, 2022 S.844-855In this work we describe the possible transitions for the hierarchical structure that describes an image in Gaussian scale space. Until now, this tree structure has only been used for topological segmentation.

Free-space-coupled wavelength-scale disk resonators
Nanophotonics, 2022 Optical microresonators with low quality factor (Q$Q$) can be efficiently excited by and scatter freely propagating optical waves, but those with high Q$Q$ typically cannot.

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Corner Detection Using the Affine Morphological Scale Space
, 2017 We introduce a method for corner estimation based on the affine morphological scale space (AMSS). Using some explicit known formula about corner evolution across AMSS, proven by Alvarez and Morales in 1997, we define a morphological cornerness measure ...

PDE-Constrained Scale Optimization Selection for Feature Detection in Remote Sensing Image Matching
MathematicsFeature detection and matching is the key technique for remote sensing image processing and related applications. In this paper, a PDE-constrained optimization model is proposed to determine the scale levels advantageous for feature detection. A variance

Scale Development for Environmental Perception of Public Space
Frontiers in Psychology, 2020 We developed a psychometric scale for measuring the subjective environmental perception of public spaces. In the scale development process, we started with an initial pool of 85 items identified from the literature that were related to environmental ...

Scale-space theory for auditory signals
, 2015 We show how the axiomatic structure of scale-space theory can be applied to the auditory domain and be used for deriving idealized models of auditory receptive fields via scale-space principles.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Information measures in scale-spaces [PDF]
IEEE Transactions on Information Theory, 1999 Summary: This correspondence investigates Rényi's generalized entropies under linear and nonlinear scale-space evolutions of images. Scale-spaces are useful computer vision concepts for both scale analysis and image restoration. We regard images as densities and prove monotony and smoothness properties for the generalized entropies.
