A novel technique for analysing histogram equalized medical images using superpixels

Computer Assisted Surgery, 2019
We present a novel technique to distinguish between an original image and its histogram equalized version. Histogram equalization and superpixel segmentation such as SLIC (simple linear iterative clustering) are very popular image processing tools. Based

Image Segmentation of Brain MRI Based on LTriDP and Superpixels of Improved SLIC

Brain Sciences, 2020
Non-uniform gray distribution and blurred edges often result in bias during the superpixel segmentation of medical images of magnetic resonance imaging (MRI).

Machine-Related Backgrounds in the SiD Detector at ILC

, 2006
With a multi-stage collimation system and magnetic iron spoilers in the tunnel, the background particle fluxes on the ILC detector can be substantially reduced.

Research on Fine Water Body Extraction From SAR Images Based on Superpixel Segmentation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The water body extraction technology based on superpixel segmentation in SAR images faces challenges such as insufficient precision in extracting fine water boundaries under speckle noise and complex scattering conditions.

gSLICr: SLIC superpixels at over 250Hz

, 2015
We introduce a parallel GPU implementation of the Simple Linear Iterative Clustering (SLIC) superpixel segmentation. Using a single graphic card, our implementation achieves speedups of up to $83\times$ from the standard sequential implementation. Our implementation is fully compatible with the standard sequential implementation and the software is now

Schnelle RASER‐MRT

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Schnelle RASER‐MRT ermöglicht Bildgebung ohne RF‐Anregung. Stattdessen wird eine Populationsinversion der Kernspins durch SABRE‐Hyperpolarisation erzeugt, die eine Selbstanregung durch RASER ermöglicht. Wenn die gewünschte transversale Magnetisierung aufgebaut ist, wird herkömmliche EPI‐Kodierung ausgelöst, um das Bild aufzuzeichnen.

Mechanism elucidation of cell‐selective fluorescent probes

Smart Molecules, Volume 4, Issue 1, March 2026.
This perspective outlines five mechanistic strategies—Protein‐oriented, carbohydrate‐oriented, lipid‐oriented, gating‐oriented, and metabolism‐oriented live‐cell distinctions—for achieving cell‐selective fluorescence in live‐cell imaging. By classifying probes based on their interactions with proteins, carbohydrates, lipids, transporters, or metabolic ...

A chromosome‐scale genome of Sarracenia purpurea reveals a significant expansion of plant defense and stress response gene families following paleopolyploidization

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Plant carnivory evolved through gene co‐option and whole genome duplications (WGDs) over millions of years in at least 13 independent flowering plant lineages, but its genetic mechanisms remain largely unknown. To elucidate these mechanisms in Sarraceniaceae, we sequenced and assembled the Sarracenia purpurea genome and conducted a comparative

Local Variation as a Statistical Hypothesis Test

, 2015
The goal of image oversegmentation is to divide an image into several pieces, each of which should ideally be part of an object. One of the simplest and yet most effective oversegmentation algorithms is known as local variation (LV) (Felzenszwalb and ...
