Towards Automatic Skeleton Extraction With Skeleton Grafting

IEEE Transactions on Visualization and Computer Graphics, 2021
This article introduces a novel approach to generate visually promising skeletons automatically without any manual tuning. In practice, it is challenging to extract promising skeletons directly using existing approaches. This is because they either cannot fully preserve shape features, or require manual intervention, such as boundary smoothing and ...

Co-skeletons: Consistent curve skeletons for shape families [PDF]

Computers & Graphics, 2020
We present co-skeletons, a new method that computes consistent curve skeletons for 3D shapes from a given family. We compute co-skeletons in terms of sampling density and semantic relevance, while preserving the desired characteristics of traditional, per-shape curve skeletonization approaches.

Skeletonization of Plant Point Cloud Data Using Stochastic Optimization Framework

Frontiers in Plant Science, 2020
Skeleton extraction from 3D plant point cloud data is an essential prior for myriads of phenotyping studies. Although skeleton extraction from 3D shapes have been studied extensively in the computer vision and graphics literature, handling the case of ...

Living Skeletons:

, 2023
There are striking similarities between Sinai trafficking and human trafficking for ransom in Libya. This chapter presents evidence to compare the practices, including the experiences of detainees in the holding camps, the torture methods used to extract ransoms, and the use of mobile phones to broadcast the torture to relatives and facilitate payments.

A Fast and Efficient Thinning Algorithm for Binary Images

Journal of ICT Research and Applications, 2014
Skeletonization “also known as thinning” is an important step in the pre-processing phase in many of pattern recognition techniques. The output of Skeletonization process is the skeleton of the pattern in the images.

Branch Identification and Junction Points Location for Apple Trees Based on Deep Learning

Remote Sensing, 2022
Branch identification is key to the robotic pruning system for apple trees. High identification accuracy and the positioning of junction points between branch and trunk are important prerequisites for pruning with a robotic arm.

Skeleton-Based Scagnostics [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2018
Scatterplot matrices (SPLOMs) are widely used for exploring multidimensional data. Scatterplot diagnostics (scagnostics) approaches measure characteristics of scatterplots to automatically find potentially interesting plots, thereby making SPLOMs more scalable with the dimension count.

Four Severity Levels for Grading the Tortuosity of a Retinal Fundus Image

Journal of Imaging, 2022
Hypertensive retinopathy severity classification is proportionally related to tortuosity severity grading. No tortuosity severity scale enables a computer-aided system to classify the tortuosity severity of a retinal image. This work aimed to introduce a

Correcting curvature-density effects in the Hamilton-Jacobi skeleton [PDF]

, 2006
The Hainilton-Jacobi approach has proven to be a powerful and elegant method for extracting the skeleton of two-dimensional (2-D) shapes. The approach is based on the observation that the normalized flux associated with the inward evolution of the object

Accuracy Assessment of Joint Angles Estimated from 2D and 3D Camera Measurements

Sensors, 2022
To automatically evaluate the ergonomics of workers, 3D skeletons are needed. Most ergonomic assessment methods, like REBA, are based on the different 3D joint angles.
