Asymmetric Dual-Stream Networks for Lightweight RGB-D Salient Object Detection

Journal of Shanghai Jiaotong University (Science) 2025年 1-11页

作者： Wang, Yan Zheng, Wanlu Xia, Yaozheng Wang, Shaorong School of Information Science and Technology Beijing Forest University Beijing100083 China Engineering Research Center for Forestry-oriented Intelligent Information Processing of National Forestry and Grassland Administration Beijing100083 China Beijing Virtual Simulation and Visualization Engineering Center Beijing100871 China

Integrating image and depth information for RGB-D salient object detection has become a research hotspot in the field of saliency detection. Balancing the efficiency and performance of salient object detection models under resource constraints is a key challenge. To address this, this paper proposes an asymmetric lightweight network suitable for real-time RGB-D salient object detection tasks. The network reduces the number of network parameters by designing different lightweight feature extraction networks for different input modalities. Additionally, a multi-modal feature enhancement fusion module is designed to effectively fuse multi-modal features while compensating for the information loss caused by the lightweight backbone network. Moreover, this paper utilizes a global context module for dense decoding, aggregating local and global information of multi-scale features without significantly increasing computational complexity. The experimental results on five benchmarks show that the proposed lightweight RGB-D salient object detection network not only outperforms most mainstream models quantitatively and qualitatively, but also significantly outperforms other models in terms of efficiency, only with a parameter count of 5.1 million and a computational load of 0.77 gigaflops. This achievement validates the proposed method’s ability to achieve lightweight salient object detection while maintaining high efficiency. © Shanghai Jiao Tong University 2024.

Alexandria Engineering Journal 2025年 128卷 281-296页

The inherent inability to obtain real-time quality measurements in calcined kilns poses significant challenges for maintaining optimal production stability. This research introduces an intelligent control method for calcined kiln product quality, leveraging a multivariable integrated deep learning model to predict and regulate quality by manipulating production actuators. A feature screening process was conducted by combining grey relative correlation, feature extraction was performed using Time Series Convolutional model, quality classification was carried out by Support Vector Machine model, and the GTS model was constructed to predict the quality of the calcined kiln product. An intelligent fuzzy control system was established to fine-tune operational parameters based on quality forecasts, with the goal of direct quality. Experimental validation using industrial furnace data demonstrates the effectiveness of the model, achieving 87.55 % prediction accuracy, and confirms the operational viability of the control strategy. This study provides a scientific approach to managing calcining kiln quality, enhancing production efficiency and facilitating the implementation of intelligent control in calcining operations.

As distance education rapidly appears on the horizon, distance learning technologies are becoming more important in delivering contents and allowing collaboration between students and teachers in globally disparate environments. One of the recent innovative technologies to be explored in distance learning field is immersive environments and sense of presence that offers. The primary purpose of this research is to study the sense of presence—the sense of "being there"—using an immersive environment. While this is a work-in-progress, the authors provide preliminary results and conclusions. © 2014 by Knowledge Systems Institute Graduate School.

Most football simulators available use computer simulation to mimic football motion in a virtual environment. These kinds of simulations, while fun and interactive, are primarily for entertainment rather than as a training tool. In this paper, we present a virtual training system for football kicking based on computer sensing and football impact dynamics using real-time wireless feedback. It is designed as a computer-assisted training system that will give a kicker the ability to practice off the field and receive the detailed feedback comparable yet more quantitative than they would experience at a training camp. In addition, it enables football coaches with quantitative data to design player-specific training program for kickers in order to achieve a goal with more precision. The system includes a force-sensing panel to determine the position and velocity as initial data, real-time wireless feedback to calibrate the football kicking dynamics model, and an advanced visualization environment designed to recreate the realistic atmosphere of all major football stadiums. The system has been designed and tested in a lab environment. The preliminary results show that the wireless signal is sensitive enough to detect football positions on the fly. The data collected in real-time can be used to calibrate the football dynamics model in predicting the final position of the football with respect to the field goal, which is visualized using 3D stereoscopic technology.
