Shape descriptors for mode-shape recognition and model updating [PDF]

open access: yes, 2009
The most widely used method for comparing mode shapes from finite elements and experimental measurements is the Modal Assurance Criterion (MAC), which returns a single numerical value and carries no explicit information on shape features. New techniques,

Monte Carlo convex hull model for classification of traditional Chinese paintings [PDF]

open access: yes, 2015
While artists demonstrate their individual styles through paintings and drawings, how to describe such artistic styles well selected visual features towards computerized analysis of the arts remains to be a challenging research problem. In this paper, we

An SIFT-Based Fast Image Alignment Algorithm for High-Resolution Image

open access: yesIEEE Access, 2023
To solve the problem of high-resolution image alignment time overhead, an SIFT-based fast image alignment algorithm is presented. The overlap region of images is computed in detail by phase correlation algorithm to avoid a lot of useless calculations of ...

Action Classification with Locality-constrained Linear Coding [PDF]

open access: yes, 2014
We propose an action classification algorithm which uses Locality-constrained Linear Coding (LLC) to capture discriminative information of human body variations in each spatiotemporal subsequence of a video sequence. Our proposed method divides the input

Anomaly Detection Based on Local Nearest Neighbor Distance Descriptor in Crowded Scenes

open access: yesThe Scientific World Journal, 2014
We propose a novel local nearest neighbor distance (LNND) descriptor for anomaly detection in crowded scenes. Comparing with the commonly used low-level feature descriptors in previous works, LNND descriptor has two major advantages.
