Bag of contour fragments for robust shape classification

X Wang, B Feng, X Bai, W Liu, LJ Latecki - Pattern recognition, 2014 - Elsevier
Shape representation is a fundamental problem in computer vision. Current approaches to
shape representation mainly focus on designing low-level shape descriptors which are …

Shape recognition by bag of skeleton-associated contour parts

W Shen, Y Jiang, W Gao, D Zeng, X Wang - Pattern Recognition Letters, 2016 - Elsevier
Contour and skeleton are two complementary representations for shape recognition.
However combining them in a principal way is nontrivial, as they are generally abstracted by …

[HTML][HTML] Towards the characterization of crop and weeds at leaf scale: A large comparison of shape, spatial and textural features

JA Vayssade, G Jones, JN Paoli - Smart Agricultural Technology, 2023 - Elsevier
In the context of crop and weeds discrimination, different methods are used to detect and
classify plants from an acquisition system. Various estimators and descriptors are commonly …

Automated classification of petroglyphs

M Seidl, E Wieser, C Alexander - Digital Applications in Archaeology and …, 2015 - Elsevier
In this paper, we address the problem of automated petroglyph classification in a large real-
world dataset. The dataset which contains more than 1000 petroglyphs is based on tracings …

Shape matching by part alignment using extended chordal axis transform

Z Yasseen, A Verroust-Blondet, A Nasri - Pattern Recognition, 2016 - Elsevier
One of the main challenges in shape matching is overcoming intra-class variation where
objects that are conceptually similar have significant geometric dissimilarity. The key to a …

A graph-based ranked-list model for unsupervised distance learning on shape retrieval

DCG Pedronette, J Almeida, RS Torres - Pattern Recognition Letters, 2016 - Elsevier
Several re-ranking algorithms have been proposed recently. Some effective approaches are
based on complex graph-based diffusion processes, which usually are time consuming and …

Shape decomposition and classification by searching optimal part pruning sequence

C Wang, Z Lai - Pattern Recognition, 2016 - Elsevier
Representing shapes in terms of meaningful parts is a fundamental problem in shape
analysis and part-based object representation. Decomposition methods typically utilize …

Graph-based shape similarity of petroglyphs

M Seidl, E Wieser, M Zeppelzauer, A Pinz… - Computer Vision-ECCV …, 2015 - Springer
Petroglyphs can be found on rock panels all over the world. The possibilities of digital
photography and more recently various 3D scanning methods opened a new stage for the …

Centroid based tree-structured data clustering using vertex/edge overlap and graph edit distance

D Dinler, MK Tural, NE Ozdemirel - Annals of Operations Research, 2020 - Springer
We consider a clustering problem in which the data objects are rooted m-ary trees with
known node correspondence. We assume that the nodes of the trees are unweighted, but …
