Abstract ：
Sports video captioning in real application scenarios requires both entities and specific scenes. However, it is difficult to extract this fine-grained information solely from the video content. This paper introduces an Explicit & Implicit Knowledge-Augmented Network for Entity-Aware Sports Video Captioning (EIKA), which leverages both explicit game-related knowledge (i.e., the set of involved player entities) and implicit visual scene knowledge extracted from the training set. Our innovative Entity-Video Interaction Module (EVIM) and Video-Knowledge Interaction Module (VKIM) are instrumental in enhancing the extraction of entity-related and scene-specific video features, respectively. The spatiotemporal information in video is encoded by introducing the Spatial-Temporal Modeling Module (STMM). And the designed Scene-To-Entity (STE) decoder fully utilizes the two kinds of knowledge to generate informative captions with the distributed decoding approach. Extensive evaluations on the VC-NBA-2022, Goal and NSVA datasets demonstrate that our method has the leading performance compared with existing methods.

Abstract ：
Existing methods for detecting anomalies in digital light processing (DLP) 3D printing and performing in-situ repairs can reduce most defects and improve success rates. However, since printing control parameters cannot adapt to real-time printing conditions, anomalies may persist across successive layers, and continuous repairs could ultimately lead to printing failure. Therefore, achieving stable printing quality requires integrating anomaly detection with the dynamic adjustment of control parameters. In this paper, we propose a hybrid approach that combines physical models with real-time status data to achieve quality-reliable DLP 3D printing. We developed a status data acquisition scheme to monitor printing status, including the downward force exerted on the printing platform, curing temperatures, resin levels, and surface morphology. Analyzing the collected data provides both status and anomaly information, enabling in-situ repair strategies to address abnormalities with minimal disruption to the printing process. Additionally, an Extended Kalman Filter integrates status data with physical models to dynamically optimise printing parameters. Experimental results show that the proposed scheme effectively addresses typical anomalies, optimises printing times, and significantly improves success rates while preserving the mechanical performance of printed models. Furthermore, the approach adapts to varying printing status, resin materials, and models.

Abstract ：
Face Anti-Spoofing (FAS) plays a critical role in safeguarding face recognition systems, while previous FAS methods suffer from poor generalization when applied to unseen domains. Although recent methods have made progress via domain generalization technology, they are still sensitive to variations in face quality caused by task-irrelevant factors like camera and illumination. In this paper, we propose a novel Quality-Invariant Domain Generalization method (QIDG) with a teacher-student architecture, which aligns liveness features into a quality-invariant space to alleviate interference from task-irrelated factors. Specifically, QIDG utilizes the teacher model to produce face quality representations, which serve as the guidance for the student model to explore the quality-invariant space. To seek this space, the student model devises two novel modules, i.e., a dual adversarial learning module (DAL) and a quality feature assembly module (QFA). The former produces domain-invariant liveness features and task-irrelated quality features. While the latter assembles these two features from the same faces into complete quality representations, as well as assembles these two features from living faces in different domains. In this way, QIDG not only achieves the alignment of the domain-invariant liveness features to the quality-invariant space, but also promotes compactness of living faces from different domains in the feature space. Extensive cross-domain experiments demonstrate the superiority of our method on five public databases.

Abstract ：
Image and text retrieval is a crucial topic in the fields of language and vision. The key to successful Image-Text retrieval is achieving accurate cross-modal representation and capturing essential correlations between image-sentence or words-regions. While existing work has designed intricate interactions to capture these correlations, challenges remain due to inadequate feature representations, such as insufficient text descriptions of image and ambiguous region representations. To address these challenges, we propose a novel approach, multi-view and region reasoning semantic enhancement, for image and text retrieval, which aims to enhance the semantic representation of features from both textual and visual modalities. Specifically, considering that an image can have multiple corresponding texts from different perspectives, with each text describing a single view, we devise a multi-view textual semantic enhancement module. This module takes advantage of the positive textual cues provided by corresponding image to make up for the limited knowledge in single-text views and produce a comprehensive image-based textual representation. Then, to address the semantic diversity of an image, we design a region reasoning semantic enhancement module that employs a graph structure to integrate both semantic and spatial reasoning knowledge from different regions, thereby clarifying the semantics of image regions and enhancing the overall semantic understanding of these areas. Extensive experiments and analyses demonstrate the superior performance of the proposed method on the Flickr30K and MSCOCO datasets, validating the effectiveness of the proposed solution.

Abstract ：
Digital light processing (DLP) 3D printing has attracted significant attention for its rapid printing speed, high accuracy, and diverse applications. However, the continuous DLP printing process releases substantial heat, resulting in a swift temperature rise in the curing area, which may lead to printing failures. Due to the lack of effective means to measure real-time temperature changes of the curing surface during continuous DLP 3D printing, the prevailing approach is to predict temperature variations during printing via numerical simulation. Nevertheless, temperature prediction methods relying solely on numerical simulation tend to be slow and overlook heat exchange dynamics during printing, potentially resulting in prediction inaccuracies, particularly for complex models. To address these issues, this paper proposes a method to combine numerical simulation and a machine learning approach for temperature prediction in the DLP 3D printing process, along with a printing control scheme generation method. Firstly, the ( m + n )th order autocatalytic kinetic model considering the light intensity and the Beer-Lambert law are employed to formulate the heat calculation equation for the photopolymer resin curing reaction. Subsequently, a heat exchange calculation equation is established based on Fourier heat conduction law and Newton's cooling equation. A numerical simulation model for temperature changes during the printing process is then developed by integrating the heat calculation equation, heat exchange calculation equation, and measurement data from Photo-DSC. Furthermore, a temperature measurement device for the printing process is designed to validate the accuracy of the numerical simulation. Following this, an improved Long Short-term Memory (LSTM) network is proposed, using temperature change data generated by the numerical simulation model to train the network for rapid (2 x 10 -4 s/layer) prediction of temperature changes during printing. Finally, aiming for the shortest printing time, an optimized control scheme planning algorithm and a target function are designed based on the model's temperature change data and the monomer's flash point to ensure the temperature remains below this threshold. This algorithm can automatically generate the optimal printing control scheme for any model. Experimental results demonstrate that the proposed temperature prediction method can predict temperature variation accurately. Based on this, the generated printing control scheme can guarantee efficient and high-quality manufacturing for any model.

Abstract ：
Face anti-spoofing (FAS) plays a vital role in securing face recognition systems. Previous approaches usually learn spoofing features from a single perspective, in which only universal cues shared by all attack types are explored. However, such single-perspective-based approaches ignore the differences among various attacks and commonness between certain attacks and bona fides, thus tending to neglect some non-universal cues that contain strong discernibility against certain types. As a result, when dealing with multiple types of attacks, the above approaches may suffer from the uncomprehensive representation of bona fides and spoof faces. In this work, we propose a novel Advanced Multi-Perspective Feature Learning network (AMPFL), in which multiple perspectives are adopted to learn discriminative features, to improve the performance of FAS. Specifically, the proposed network first learns universal cues and several perspective-specific cues from multiple perspectives, then aggregates the above features and further enhances them to perform face anti-spoofing. In this way, AMPFL obtains features that are difficult to be captured by single-perspective-based methods and provides more comprehensive information on bona fides and spoof faces, thus achieving better performance for FAS. Experimental results show that our AMPFL achieves promising results in public databases, and it effectively solves the issues of single-perspective-based approaches.

Abstract ：
In recent years, a series of continuous fabrication technologies based on digital light processing (DLP) 3D printing have emerged, which have significantly improved the speed of 3D printing. However, limited by the resin filling speed, those technologies are only suitable to print hollow structures. In this paper, an optimized protocol for developing continuous and layer-wise hybrid DLP 3D printing mode is proposed based on computational fluid dynamics (CFD). Volume of the fluid method is used to simulate the behavior of resin flow while Poiseuille flow, Jacobs working curve, and Beer-Lambert law are used to optimize the key control parameters for continuous and layer-wise printing. This strategy provides a novel simulation-based method development scenario to establish printing control parameters that are applicable to arbitrary structures. Experiments verified that the printing control parameters obtained by simulations can effectively improve the printing efficiency and the applicability of DLP 3D printing.

Abstract ：
The core of cross-modal hashing methods is to map high dimensional features into binary hash codes, which can then efficiently utilize the Hamming distance metric to enhance retrieval efficiency. Recent development emphasizes the advantages of the unsupervised cross-modal hashing technique, since it only relies on relevant information of the paired data, making it more applicable to real-world applications. However, two problems, that is intro-modality correlation and inter-modality correlation, still have not been fully considered. Intra-modality correlation describes the complex overall concept of a single modality and provides semantic relevance for retrieval tasks, while inter-modality correction refers to the relationship between different modalities. From our observation and hypothesis, the dependency relationship within the modality and between different modalities can be constructed at the object level, which can further improve cross-modal hashing retrieval accuracy. To this end, we propose a Visual-textful Correlation Graph Hashing (OVCGH) approach to mine the fine-grained object-level similarity in cross-modal data while suppressing noise interference. Specifically, a novel intra-modality correlation graph is designed to learn graph-level representations of different modalities, obtaining the dependency relationship of the image region to image region and the tag to tag in an unsupervised manner. Then, we design a visual-text dependency building module that can capture correlation semantic information between different modalities by modeling the dependency relationship between image object region and text tag. Extensive experiments on two widely used datasets verify the effectiveness of our proposed approach.

Abstract ：
Hamming space retrieval is a hot area of research in deep hashing because it is effective for large-scale image retrieval. Existing hashing algorithms have not fully used the absolute boundary to discriminate the data inside and outside the Hamming ball, and the performance is not satisfying. In this paper, a boundary-aware contrastive loss is designed. It involves an exponential function with absolute boundary (i.e., Hamming radius) information for dissimilar pairs and a logarithmic function to encourage small distance for similar pairs. It achieves a push that is bigger than the pull inside the Hamming ball, and the pull is bigger than the push outside the ball. Furthermore, a novel Boundary-Aware Hashing (BAH) architecture is proposed. It discriminatively penalizes the dissimilar data inside and outside the Hamming ball. BAH enables the influence of extremely imbalanced data to be reduced without up-weight to similar pairs or other optimization strategies because its exponential function rapidly converges outside the absolute boundary, making a huge contrast difference between the gradients of the logarithmic and exponential functions. Extensive experiments conducted on four benchmark datasets show that the proposed BAH obtains higher performance for different code lengths, and it has the advantage of handling extremely imbalanced data.
