Facial Expression Recognition via Non-Negative Least-Squares Sparse Coding

open access: yesInformation, 2014
Sparse coding is an active research subject in signal processing, computer vision, and pattern recognition. A novel method of facial expression recognition via non-negative least squares (NNLS) sparse coding is presented in this paper.

Multiscale Reference-Aided Attentive Feature Aggregation for Person Re-Identification

open access: yesIEEE Access, 2021
In person re-identification (Re-ID), increasing the diversity of pedestrian features can improve recognition accuracy. In standard convolutional neural networks (CNNs), the receptive fields of neurons in each layer are designed to have the same size ...

No-Reference Image Quality Assessment Based on Edge Pattern Feature in the Spatial Domain

open access: yesIEEE Access, 2021
This paper proposes a general-purpose no-reference image quality assessment (NR-IQA) method that investigates the image’s structure information from a new aspect, i.e., the characteristic of image edge profiles that depict the directional property

SiamCCF: Siamese visual tracking via cross‐layer calibration fusion

open access: yesIET Computer Vision, 2023
Siamese networks have attracted wide attention in visual tracking due to their competitive accuracy and speed. However, the existing Siamese trackers usually leverage a fixed linear aggregation of feature maps, which does not effectively fuse the ...

Improving the Separability of Deep Features with Discriminative Convolution Filters for RSI Classification

open access: yesISPRS International Journal of Geo-Information, 2018
The extraction of activation vectors (or deep features) from the fully connected layers of a convolutional neural network (CNN) model is widely used for remote sensing image (RSI) representation.

Image Recognition CAPTCHAs [PDF]

open access: yes, 2004
CAPTCHAs are tests that distinguish humans from software robots in an online environment [3,14,7]. We propose and implement three CAPTCHAs based on naming images, distinguishing images, and identifying an anomalous image out of a set. Novel contributions include proposals for two new CAPTCHAs, the first user study on image recognition CAPTCHAs, and a ...

One-Shot Distributed Generalized Eigenvalue Problem (DGEP): Concept, Algorithm and Experiments

open access: yesApplied Sciences, 2022
This paper focuses on the design of a distributed algorithm for generalized eigenvalue problems (GEPs) in one-shot communication. Since existing distributed methods for eigenvalue decomposition cannot be applied to GEP, a general one-shot distributed GEP

Compressively Sensed Image Recognition

open access: yes, 2018
Compressive Sensing (CS) theory asserts that sparse signal reconstruction is possible from a small number of linear measurements. Although CS enables low-cost linear sampling, it requires non-linear and costly reconstruction. Recent literature works show
