Coal-rock interface identification scheme based on Hough transform

Gong-kuang zidonghua, 2015
A coal-rock interface identification scheme based on Hough transform was proposed according to characteristic of coal-rock image, namely boundary between coal seam and rock seam is significant and linear.

A Novel Gradient-Weighted Voting Approach for Classical and Fuzzy Circular Hough Transforms and Their Application in Medical Image Analysis—Case Study: Colonoscopy

Applied Sciences, 2023
Classical circular Hough transform was proven to be effective for some types of colorectal polyps. However, the polyps are very rarely perfectly circular, so some tolerance is needed, that can be ensured by applying fuzzy Hough transform instead of the ...

Sleep‐trackers in the wild: A faceted taxonomy for information and interaction design

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Consumer‐grade sleep‐tracking technologies (CSTs) have brought sleep into everyday data practices, reframing it from a clinical concern into a site of personal optimization and reflection. Yet existing taxonomies of sleep‐tracking often medicalize users and overlook the complexity of sleep‐tracking technologies. This paper presents SleepTax, a

An algebraic approach to Hough transforms

Journal of Algebra, 2012
The main purpose of this paper is to lay the foundations of a general theory which encompasses the features of the classical Hough transform and extend them to general algebraic objects such as affine schemes. The main motivation comes from problems of detection of special shapes in medical and astronomical images.

Artificial intelligence for adaptive neuromodulation in drug‐resistant epilepsy

Epilepsia, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects nearly one third of people with epilepsy and is associated with substantial cognitive, psychiatric, and mortality burdens. For patients who are not candidates for resection or laser interstitial thermal therapy, neuromodulation therapies such as vagus nerve stimulation, deep brain stimulation, and ...

Representing Directions for Hough Transforms [PDF]

, 2007
Many algorithms in computer vision operate with directions, i. e. with representations of 3D-points by ignoring their distance to the origin. Even though minimal parametrizations of directions may contain singularities, they can enhance convergence in optimization algorithms and are required e. g. for accumulator spaces in Hough transforms.

Laser‐Based In Situ Diagnostics of Temperature and Material‐Growth Dynamics in Photothermal Laser Nanoprinting of ZnO

Laser &Photonics Reviews, EarlyView.
This work elucidates the previously unknown thermal dynamics during sub‐micrometer photothermal laser printing of zinc oxide using a non‐invasive transmission‐based in situ measurement. The elevated temperatures are shown to be highly localized around the laser focal spot, reaching average temperature increases of about 113 K per mW of laser power ...

Toward a Framework for Understanding Localization in Its Institutional Context: A Systems Perspective for Incorporating Local Values

Public Administration and Development, EarlyView.
ABSTRACT This paper explores how we might integrate local traditional values into a systems approach for analyzing and maximizing localization in the context of foreign aid. The paper situates localization and its operationalization in the older and broader literature on the political economy of foreign aid.
