Linear spatio-temporal scale-space [PDF]

open access: yes, 1997
This article shows how a linear scale-space formulation previously expressed for spatial domains extends to spatio-temporal data. Starting from the main assumptions that: (i) the scale-space should be generated by convolution with a semi-group of filter ...

Color image segmentation using a spatial k-means clustering algorithm [PDF]

open access: yes, 2006
This paper details the implementation of a new adaptive technique for color-texture segmentation that is a generalization of the standard K-Means algorithm. The standard K-Means algorithm produces accurate segmentation results only when applied to images

Selected Applications of Scale Spaces in Microscopic Image Analysis

open access: yesCybernetics and Information Technologies, 2015
Image segmentation methods can be classified broadly into two classes: intensity-based and geometry-based. Edge detection is the base of many geometry-based segmentation approaches.

NCLG-UNet: A Lightweight U-Net Based on Non-Causal State Space Duality and Laplacian Guidance for Medical Image Segmentation

open access: yesIEEE Access
Medical image segmentation requires accurate lesion boundary delineation under complex structural variations and interference conditions. However, lightweight models are constrained by their limited parameter capacity and computational budgets, making it

Performance characterization of clustering algorithms for colour image segmentation [PDF]

open access: yes, 2006
This paper details the implementation of three traditional clustering techniques (K-Means clustering, Fuzzy C-Means clustering and Adaptive K-Means clustering) that are applied to extract the colour information that is used in the image segmentation ...

Coarse-to-Fine Segmentation With Shape-Tailored Scale Spaces

open access: yesCoRR, 2016
We formulate a general energy and method for segmentation that is designed to have preference for segmenting the coarse structure over the fine structure of the data, without smoothing across boundaries of regions. The energy is formulated by considering data terms at a continuum of scales from the scale space computed from the Heat Equation within ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Automatic segmentation of skin cancer images using adaptive color clustering [PDF]

open access: yes, 2006
This paper presents the development of an adaptive image segmentation algorithm designed for the identification of the skin cancer and pigmented lesions in dermoscopy images. The key component of the developed algorithm is the Adaptive Spatial K-Means (A-

The Empirical Watershed Wavelet

open access: yesJournal of Imaging, 2020
The empirical wavelet transform is an adaptive multi-resolution analysis tool based on the idea of building filters on a data-driven partition of the Fourier domain.
