Abstract ：
This article irons out the issue of recursive state estimation for mobile robot localization under a multiple description coding scheme. For the sake of optimizing the utilization of channel resources, a novel two-description coding scheme is first introduced to facilitate measurements transmission by encoding the data into two equally important descriptions. The raw data is then reconstructed according to the number of the descriptions received by the decoders. Meanwhile, two random variables with Bernoulli distribution are used to display the occurrences of the packet dropouts in both parallel independent channels from the encoders to the decoders. The primary objective of this article is to develop a desired estimator tailored to the mobile robot localization problem in the presence of the data encoding-decoding mechanism, where the upper bound on the estimation error covariance is first guaranteed by virtue of mathematical induction and then is minimized by designing the estimator gain appropriately. Furthermore, the estimation performance is analyzed through the implementation of a sufficient condition. Finally, experimental examples are employed to verify the applicability of the proposed encoding-decoding-based recursive state estimation scheme for mobile robot localization.

Abstract ：
Sulfur dioxide ( SO2 ) emissions are the main problems causing the air pollution and respiratory disease, which makes desulfurization important in the coal combustion and chemical industry processes. The wet-flue-gas desulfurization (WFGD) is currently an effective method to deal with this issue. However, the WFGD system is actually a complex process with multi-variable coupling, high nonlinearity and large time-delay, which brings great challenges for the traditional mechanism-based modeling and control. In this paper, a neurodynamics-driven model predictive control (NDMPC) with soft-measurement is proposed to predict and control the dynamics of SO2 to improve the operational performance of the WFGD system. First, we design a self-organizing fuzzy neural network (SOFNN) as the soft-measuring model, which is driven by the data and neurodynamics to adaptively predict SO2 in the WFGD system. Second, the designed SOFNN is considered as a predictive model that can give the predicted values for the future moments. Third, we also design a loss function where the one-step output of the predictive model and the control law are the independent variables. The resulting rolling optimization can give the optimal control law sequence by minimizing the loss function. Finally, simulation experiments on the practical data from the WFDG system show that the NDMPC outperforms the other methods in terms of the soft-measurement and control performance, especially generally reducing the SO2 emission and economic cost by 60.25% and 22.27%, respectively. Note to Practitioners-The proposed NDMPC framework presents an effective method to solve the optimal feedstock. which can reduce costs while maintaining the operational efficiency of WFGD system. The optimal solution of NDMPC is dominated by soft-measuring model (SOFNN) to some extent. In the practical applications of WFGD systems, it is better for practitioners to obtain more historical data so that the more accurate soft-measuring model is available for the optimal solution of NDMPC.

Abstract ：
Existing group activity recognition methods generally use optical flow image to represent motion within videos, which often struggle to capture the movements of individuals inaccurately. In this paper, we explore the effectiveness of more kinds of motion information for group activity recognition. We propose a novel multi- scale MOtion-based relational reasoning framework for Group Activity Recognition (MOGAR). It combines joint motion (intra-individual level) with trajectory (individual-level) and individual position (inter-individual level) to acquire richer activity representation. Specifically, it involves two branches: the trajectory branch utilizes individuals' trajectories and positions to extract the motion feature at the individual and inter-individual levels. The joint branch extracts the motion features at the intra-individual level. Furthermore, the gated recurrent units (GRU) and Transformers are employed to enhance the corresponding features through gating mechanism and self-attention mechanism. The features from the two branches are concatenated for group activity recognition. The experiments on two public datasets demonstrate that our method achieves competitive performance and has potential benefits in terms of computational complexity.

Abstract ：
Due to the light absorption and scattering in waterbodies, acquired underwater images frequently suffer from color cast, blur, low contrast, noise, etc., which seriously degrade the image quality and affect their subsequent applications. Therefore, it is necessary to propose a reliable and practical underwater image quality assessment (IQA) model that can faithfully evaluate underwater image quality. To this end, in this article, we establish a novel quality assessment model for underwater images by in-depth analysis and characterization of multiple image properties. Specifically, we propose characterizing the image luminance, color cast, sharpness, contrast, fog density and noise to comprehensively describe the image quality to evaluate the underwater image quality more accurately. Dedicated features are elaborately investigated to characterize those quality-aware image properties. After feature extraction, we employ support vector regression (SVR) to integrate all the quality-aware features and regress them onto the underwater image quality score. Extensive tests performed on standard underwater image quality databases demonstrate the superior prediction performance of the proposed underwater IQA model to state-of-the-art congeneric quality assessment models.

Abstract ：
Weakly supervised group activity recognition deals with the dependence on individual-level annotations during understanding scenes involving multiple individuals, which is a challenging task. Existing methods either take the trained detectors to extract individual features or utilize the attention mechanisms for partial context encoding, followed by integration to form the final group-level representations. However, the detectors require individual-level annotations during the training phase and have a mis-detection issue, and the partial contexts extracted immediately from the whole complex scene are too ambiguous without the guidance of concrete semantics. In this article, we investigate the hierarchical structure inherent in group-level labels to extract the fine-grained semantics without using detectors for weakly supervised group activity recognition. A multi-hot encoding strategy combined with a semantic encoder is first adopted to get the label semantics embeddings. The semantic and visual scene information are then fused through a semantic decoder to obtain activity-specific features. Lastly, we employ the multi-label classification and integrate the scores of hierarchical activity labels. Experimental results show that our proposed method achieves the state-of-the-art performance on three benchmarks, and the accuracy on the Volleyball dataset exceeds the second-best method by 2%.

Abstract ：
Underwater image quality assessment (UIQA) plays a crucial role in monitoring and detecting the quality of acquired underwater images in underwater imaging systems. Currently, the investigation of UIQA encounters two major challenges. First, a lack of large-scale UIQA databases for benchmarking UIQA algorithms remains, which greatly restricts the development of UIQA research. The other limitation is that there is a shortage of effective UIQA methods that can faithfully predict underwater image quality. To alleviate these two challenges, in this paper, we first construct a large-scale UIQA database (UIQD). Specifically, UIQD contains a total of 5369 authentic underwater images that span abundant underwater scenes and typical quality degradation conditions. Extensive subjective experiments are executed to annotate the perceived quality of the underwater images in UIQD. Based on an in-depth analysis of underwater image characteristics, we further establish a novel baseline UIQA metric that integrates channel and spatial attention mechanisms and a transformer. Channel- and spatial attention modules are used to capture the image channel and local quality degradations, while the transformer module characterizes the image quality from a global perspective. Multilayer perception is employed to fuse the local and global feature representations and yield the image quality score. Extensive experiments conducted on UIQD demonstrate that the proposed UIQA model achieves superior prediction performance compared with the state-of-the-art UIQA and IQA methods.
