Navigational analysis of a humanoid using genetic algorithm with vision assistance
Multimedia Tools and Applications - Tập 79 - Trang 8125-8144 - 2020
In this paper, a novel vision assisted genetic algorithm based navigational controller has been designed for smooth and collision-free path generation of a humanoid robot. Here, sensory information regarding the nearest obstacle distance and path left to the destination are considered as the inputs to the genetic algorithm controller, and necessary turning angle is generated as the required output...... hiện toàn bộ
A 3-factor authentication access control system using RFID, fingerprint, token and code
Multimedia Tools and Applications - - Trang 1-13 - 2023
The 3-factor authentication control system is aim at providing maximum security in company’s stores, special utilities and premises where valuables are stored. A developed security system with automatic sensing was introduced using the integration of Radio Frequency Identification (RFID) card tagging system, fingerprint sensing biometric security system and Global System for Mobile communication (...... hiện toàn bộ
Efficient lightweight video person re-identification with online difference discrimination module
Multimedia Tools and Applications - Tập 81 - Trang 19169-19181 - 2021
Video person re-identification (video Re-ID) is a key technology applied to video surveillance and security. Typical person re-identification is designed to retrieve the correct match of the target image (query) from gallery images, while video Re-ID extends this to query from gallery videos. The main factors affecting the video Re-ID model are: (i) a high-quality frame-level feature extractor, an...... hiện toàn bộ
A novel clustering method for static video summarization
Multimedia Tools and Applications - Tập 76 - Trang 9625-9641 - 2016
Static video summarization is recognized as an effective way for users to quickly browse and comprehend large numbers of videos. In this paper, we formulate static video summarization as a clustering problem. Inspired by the idea from high density peaks search clustering algorithm, we propose an effective clustering algorithm by integrating important properties of video to gather similar frames in...... hiện toàn bộ
Collaborative virtual reality platform for visualizing space data and mission planning
Multimedia Tools and Applications - Tập 78 - Trang 33191-33220 - 2019
This paper presents the system architecture of a collaborative virtual environment in which distributed multidisciplinary teams involved in space exploration activities come together and explore areas of scientific interest of a planet for future missions. The aim is to reduce the current challenges of distributed scientific and engineering meetings that prevent the exploitation of their collabora...... hiện toàn bộ
Tackling the class imbalanced dermoscopic image classification using data augmentation and GAN
Multimedia Tools and Applications - - Trang 1-27 - 2023
Dermoscopy is a noninvasive way to examine and diagnose skin lesions, e.g. nevus and melanoma, and is a critical step for skin cancer detection. Accurate classification of dermoscopic images can detect skin cancer at an early stage and bring social and economic impact to patients and communities. Using deep learning methods to classify dermoscopic images has shown superior performance, but existin...... hiện toàn bộ

Feature selection via uncorrelated discriminant sparse regression for multimedia analysis
Multimedia Tools and Applications - Tập 82 - Trang 619-647 - 2022
As an important part of multimedia analysis applications, feature selection has attracted much attention during the past decades. Lots of feature selection methods have been proposed, but most of them neglect to consider the correlation between the selected features, which leads to the feature redundancy problem. In this paper, we propose a novel supervised feature selection method, termed as Unco...... hiện toàn bộ
Classification methods of butterfly images based on U-net and STL-MSDNet
Multimedia Tools and Applications - Tập 82 - Trang 37039-37063 - 2023
Aiming at the lack of coarse-grained features in butterfly image classification and recognition research, low recognition accuracy, and limited spatial invariance to input data, this paper proposes a butterfly image classification method based on U-Net and STL-MSDNet. Firstly, in order to reduce the influence of complex backgrounds on butterfly image recognition, the U-Net model is used to segment...... hiện toàn bộ
Simulation analysis of prefetching image content for social networking service framework
Multimedia Tools and Applications - Tập 78 - Trang 28435-28452 - 2017
In this paper, we analyze a prefetching mechanism for image content in social networking services (SNS) based on content writers that attract a user’s interest. Our prefetching scheme aims to shorten transmission delays and enhance the accessibility to big size images included in SNS content items. The prefetching scheme deals with users of interest instead of the content of interest. Whenever a u...... hiện toàn bộ
