To solve the communication resource allocation problem of swarm robots in emergency rescue scenarios, an evolutionary game-based resource allocation strategy is proposed. The complex dynamic equation of the evolutionary game is constructed through the payoff function, cost function and utility function of the resource consumption robot. The monotonicity of the replication dynamic equation is proved and the evolutionary game equilibrium solution is obtained. For the time-varying characteristics of emergency scenarios, the evolutionary game model is optimized by introducing historical information conditions within the memory length in the evolution of replication dynamic equations. By simulation, the proposed evolutionary game model is evaluated. The results show that the distribution of the population tends to converge and exists stably after 25 iterations. By comparing the historical average income information with the current income information under different memory lengths, it is found that the convergence speed is the fastest and the convergence is the best when the medium memory length m=5.

In recent years, saliency object detection methods based on convolutional neural networks have been widely studied,and have achieved excellent performance in clear images. However, due to the low visibility of images in foggy conditions, the existing saliency object detection methods will be seriously affected or even ineffective. To address this problem, we introduce an end-to-end multi-task learning network. We design two subetworks for depth estimation and image restoration as auxiliary tasks to improve saliency object detection in foggy conditions. According to different characteristics of vision tasks, different shared layers are assigned to improve the performance of saliency object detection. Experiments show that our method has been greatly improved on both synthetic foggy datasets and real-to-world foggy datasets, outperforming many state-to-the-art saliency object detection methods.

vision transformers have recently generated significant interest in the computer vision and audio communities due to their flexibility in learning long-range relationships. However, transformers are known to be data hungry which require orders of magnitude more data [1] to train. This has motivated the research in self-supervised pretraining of audio transformers, which reduces the dependency on large amounts of labeled data and focuses on extracting concise representation of the audio spectrograms. In this paper, we propose Audio-GMML, a self-supervised transformer for general audio representations that is based on Group Masked Model Learning (GMML) and a patch aggregation strategy to improve the performance of learned representations and enforce global structure of the given audio. We evaluate our pretrained models on several downstream tasks, setting a new state-of-the-art performance on five audio and speech classification tasks. The code and pretrained weights will be made publicly available for the scientific community.

Computer vision tasks, such as object recognition, using deep learning find their place in a variety of contexts including agriculture. Regarding data, the coupling of RGB and depth modalities has already proven to be beneficial for object recognition over the use of RGB-only images. However, the lack of neural network architectures and large-size datasets dedicated to the depth modality forces us to use backbones pre-trained on RGB data using large datasets such as ImageNet. While works proposed by Eitel et al. and Aakerberg et al. rely on colorizing the depth values to match an RGB format, they do not take full advantage of the geometric properties carried by the depth modality. We demonstrated principal curvatures when used to color-encode the depth values retain more information related to the object's shape. The proposition was evaluated on the Washington RGB-D dataset and gave mitigated results mainly explained by a high confusion between similarly shaped objects, which represent an important fraction of the dataset. With the introduction of superclasses based on the geometric shape of objects (sphere, cylinder, cube,...) our model performed higher than the previous work, e.g. 3.1% precision increase for the sphere superclass. While presenting some limitations, this work opens the path for further developments.

Owing to the advances in image processing technology and large-scale datasets, companies have implemented facial authentication processes, thereby stimulating increased focus on face anti-spoofing (FAS) against realistic presentation attacks. Recently, various attempts have been made to improve face recognition performance using both global and local learning on face images;however, to the best of our knowledge, this is the first study to investigate whether the robustness of FAS against domain shifts is improved by considering global information and local cues in face images captured using self-attention and convolutional layers. This study proposes a convolutional vision transformer-based framework that achieves robust performance for various unseen domain data. Our model resulted in 7.3%p and 12.9%p increases in FAS performance compared to models using only a convolutional neural network or vision transformer, respectively. It also shows the highest average rank in sub-protocols of cross-dataset setting over the other nine benchmark models for domain generalization.

In recent years, cable-driven continuum robots have emerged as a notable focus in robotic research. Achieving a stable and precise controller for such robots requires careful consideration of measuring cable tension force. This paper introduces an innovative design and optimization approach using strain gauges to create a cable tension force sensor (CTFS) that is stable, low-noise, and cost-effective. The methodology involves finite element method (FEM) analysis and optimization to determine the optimal sensor structure based on design requirements. The CTFS design structure is fabricated with 3 types of strain gauges arrangement to conduct the generality. signalprocessing circuits for the sensor are developed to handle signals from the CTFS strain gauge bridge. Additionally, the study details the fabrication of three types of CTFS modules to comprehensively assess the proposed designs. Experimental validations, including calibration and temperature sensitivity, are conducted to verify the CTFS in various aspects. The experimental results of the cable tension force sensor shows that the CTFSs can provide high sensitivity with 0.31mV/N, 0.37586mV/N and 0.3197mV/N along with high stability for CTFS-Type1, CTFS-Type2 and CTFS-Type3 respectively. Finally, the application validation demonstrates the potential effectiveness of the cable tension force sensor for affordable, custom continuum robot actuators.
