Robust Visual Tracking Using Kernel Sparse Coding on Multiple Covariance Descriptors
In this article, we aim to improve the performance of visual tracking by combing different features of multiple modalities. The core idea is to use covariance matrices as feature descriptors and then use sparse coding to encode different features. The ...
CovLets: A Second-Order Descriptor for Modeling Multiple Features
State-of-the-art techniques for image and video classification take a bottom-up approach where local features are aggregated into a global final representation. Existing frameworks (i.e., bag of words or Fisher vectors) are specifically designed to ...
Action Recognition Using Form and Motion Modalities
Action recognition has attracted increasing interest in computer vision due to its potential applications in many vision systems. One of the main challenges in action recognition is to extract powerful features from videos. Most existing approaches ...
AMIL: Adversarial Multi-instance Learning for Human Pose Estimation
Human pose estimation has an important impact on a wide range of applications, from human-computer interface to surveillance and content-based video retrieval. For human pose estimation, joint obstructions and overlapping upon human bodies result in ...
Multichannel Attention Refinement for Video Question Answering
Video Question Answering (VideoQA) is the extension of image question answering (ImageQA) in the video domain. Methods are required to give the correct answer after analyzing the provided video and question in this task. Comparing to ImageQA, the most ...
Delving Deeper in Drone-Based Person Re-Id by Employing Deep Decision Forest and Attributes Fusion
Deep learning has revolutionized the field of computer vision and image processing. Its ability to extract the compact image representation has taken the person re-identification (re-id) problem to a new level. However, in most cases, researchers are ...
Spatial Preserved Graph Convolution Networks for Person Re-identification
Person Re-identification is a very challenging task due to inter-class ambiguity caused by similar appearances, and large intra-class diversity caused by viewpoints, illuminations, and poses. To address these challenges, in this article, a graph ...
ACMNet: Adaptive Confidence Matching Network for Human Behavior Analysis via Cross-modal Retrieval
Cross-modality human behavior analysis has attracted much attention from both academia and industry. In this article, we focus on the cross-modality image-text retrieval problem for human behavior analysis, which can learn a common latent space for ...
Multi-scale Supervised Attentive Encoder-Decoder Network for Crowd Counting
Crowd counting is a popular topic with widespread applications. Currently, the biggest challenge to crowd counting is large-scale variation in objects. In this article, we focus on overcoming this challenge by proposing a novel Attentive Encoder-Decoder ...
Machine Learning Techniques for the Diagnosis of Alzheimer’s Disease: A Review
Alzheimer’s disease is an incurable neurodegenerative disease primarily affecting the elderly population. Efficient automated techniques are needed for early diagnosis of Alzheimer’s. Many novel approaches are proposed by researchers for classification ...
Exploring Disorder-Aware Attention for Clinical Event Extraction
Event extraction is one of the crucial tasks in biomedical text mining that aims to extract specific information concerning incidents embedded in the texts. In this article, we propose a deep learning framework that aims to identify the attributes (...

Hybrid Wolf-Bat Algorithm for Optimization of Connection Weights in Multi-layer Perceptron
In a neural network, the weights act as parameters to determine the output(s) from a set of inputs. The weights are used to find the activation values of nodes of a layer from the values of the previous layer. Finding the ideal set of these weights for ...
Intelligent Classification and Analysis of Essential Genes Using Quantitative Methods
Essential genes are considered to be the genes required to sustain life of different organisms. These genes encode proteins that maintain central metabolism, DNA replications, translation of genes, and basic cellular structure, and mediate the transport ...
Active Balancing Mechanism for Imbalanced Medical Data in Deep Learning–Based Classification Models
Imbalanced data always has a serious impact on a predictive model, and most under-sampling techniques consume more time and suffer from loss of samples containing critical information during imbalanced data processing, especially in the biomedical ...
