AI Article Synopsis

  • The paper introduces a new system for detecting objects based on their contours in messy environments, starting from a specific contour model for each object class.
  • It breaks down these contour models into smaller parts called fragments and groups them into part bundles that can overlap.
  • The proposed method utilizes both local shape similarity for identifying candidate object shapes in images and global shape similarity for optimizing these configurations, while also incorporating texture information for better detection of uniquely textured objects.

Article Abstract

In this paper we propose a novel framework for contour based object detection from cluttered environments. Given a contour model for a class of objects, it is first decomposed into fragments hierarchically. Then, we group these fragments into , where a part bundle can contain overlapping fragments. Given a new image with set of edge fragments we develop an efficient voting method using local shape similarity between part bundles and edge fragments that generates high quality candidate part configurations. We then use global shape similarity between the part configurations and the model contour to find optimal configuration. Furthermore, we show that appearance information can be used for improving detection for objects with distinctive texture when model contour does not sufficiently capture deformation of the objects.

CFD analysis of heat transfer enhancement in impinging jet array by varying number of jets and spacing.

Sci Rep

January 2025

Thermal and Energetic Systems Studies Laboratory (LESTE), LR99ES31, College of Engineering, University of Monastir, 5000, Monastir, Tunisia.

Using the RANS approach with the standard k-ω turbulence model, this study offers a novel investigation into the dynamic and thermal properties of turbulent impinging jet arrays. Our study examines the combined effect of the number of jets (N) and the jet-jet spacing (S) on flow mechanisms and heat transfer performance, which is unique compared to previous research that frequently focuses on the individual effects of parameters. Through the investigation of the turbulent kinetic energy, friction coefficient, velocity contours, streamlines, pressure contours, and local and mean Nusselt numbers, we provide important information about how these parameters impact flow dynamics.

Background: Adrenal Vein Sampling (AVS) is the gold standard for categorizing primary aldosteronism (PA). However, catheterization of the right adrenal vein (RAV) can be technically challenging. This study aimed to investigate the validity of the right renal vertebral contour as fluoroscopic landmarks to help RAV orifice localization during AVS.

Purpose: In prostate cancer patients, high radiation doses to the urethra have been associated with an increased risk of severe genitourinary toxicity following dose-escalated radiotherapy. Urethra-sparing techniques have emerged as a promising approach to reduce urinary toxicity. This international survey aims to evaluate current global practices in urethra-sparing and explore future directions for the implementation of this technique in external beam radiotherapy (EBRT) for prostate cancer.

Shoulder Aesthetics: A Novel Synergy of Hyaluronic Acid Fillers and Neuromodulators.

Medical Research Inc., Wonju, Korea.

The pursuit of aesthetically pleasing shoulder contours, particularly those characterised by a sharp, angular definition, has gained significant traction in Southeast Asia. Traditionally, neuromodulators have been used to achieve these results by inducing muscle atrophy, particularly in the trapezius muscles. However, this approach can carry potential risks, such as compromised muscle function and spinal instability.
