A dataset exhibits the class imbalance problem when a target class has a very small number
of instances relative to other classes. A trivial classifier typically fails to detect a minority …

This paper proposes a novel graph matching algorithm and applies it to shape recognition
based on object silhouettes. The main idea is to match skeleton graphs by comparing the …

摘要形状匹配及分类是计算机视觉中的重要问题. 近年来, 以形状上下文为代表的基于轮廓的
形状匹配方法和以奇点图为代表的基于骨架的形状匹配方法获得了长足的发展 …

We propose a novel significance measure for skeleton pruning, called bending potential
ratio (BPR), in which the decision regarding whether a skeletal branch should be pruned or …

Body cleanliness is considered an important indicator for evaluating cow welfare. At present,
assessing the cleanliness of different cow body parts is considered as a subjective and labor …

Shape provides one of the most relevant information about an object. This makes shape one
of the most important visual attributes used to characterize objects. This paper introduces a …

In the past few years, the research studies in image-based shape representation have been
proliferating due to its usefulness and importance for various application. This field has been …

In recent years there has been a resurgence of interest in our community in the shape
analysis of 3D objects represented by surface meshes, their voxelized interiors, or surface …

Shape analysis is a very important field in computer vision. This work presents a novel and
highly discriminative shape analysis method based on the weights of a Randomized Neural …

We consider a method for computing skeletal representations based on the average
outward flux through a shrinking region, of the gradient of the Euclidean distance function to …
