Face anti-spoofing with cross-stage relation enhancement and spoof material perception.

Face Anti-Spoofing (FAS) seeks to protect face recognition systems from spoofing attacks, which is applied extensively in scenarios such as access control, electronic payment, and security surveillance systems. Face anti-spoofing requires the integration of local details and global semantic information. Existing CNN-based methods rely on small stride or image patch-based feature extraction structures, which struggle to capture spatial and cross-layer feature correlations effectively. Meanwhile, Transformer-based methods have limitations in extracting discriminative detailed features. To address the aforementioned issues, we introduce a multi-stage CNN-Transformer-based framework, which extracts local features through the convolutional layer and long-distance feature relationships via self-attention. Based on this, we proposed a cross-attention multi-stage feature fusion, employing semantically high-stage features to query task-relevant features in low-stage features for further cross-stage feature fusion. To enhance the discrimination of local features for subtle differences, we design pixel-wise material classification supervision and add a auxiliary branch in the intermediate layers of the model. Moreover, to address the limitations of a single acquisition environment and scarcity of acquisition devices in the existing Near-Infrared dataset, we create a large-scale Near-Infrared Face Anti-Spoofing dataset with 380k pictures of 1040 identities. The proposed method could achieve the state-of-the-art in OULU-NPU and our proposed Near-Infrared dataset at just 1.3GFlops and 3.2M parameter numbers, which demonstrate the effective of the proposed method.

Mothers' negative emotional expression and preschoolers' negative emotional regulation strategies in Beijing, China: The moderating effect of maternal educational attainment.

The relationship between mothers' negative emotional expression and preschoolers' negative emotional regulation has been a topic of debate. Studies have confirmed the unique effect of maternal education on children's emotional regulation. Further understanding of the role of maternal educational attainment in the relationship between mothers' emotional expression and children's emotional regulation strategies will help us better explain the possible reasons for the differences in children's emotional regulation abilities. In this study, 503 Chinese mother-child dyads were recruited. The Chinese version of the Self-Expressiveness in the Family Questionnaire (SEFQ) was used to measure the mothers' negative emotional expression, and the Emotional Regulatory Strategy Questionnaire (ERQ) was used to measure the children's negative emotional regulation strategies. The results indicated that mothers' negative emotional expression was positively related to children's negative emotional regulation strategies. Moreover, maternal educational attainment moderated this relationship. The findings of the current study demonstrate the importance of mothers' educational background, providing an important supplement to and extension of previous research on family emotions.

Maternal negative emotional expression and discipline in Beijing, China: The moderating role of educational attainment.

The current study shows that parental punitive discipline places children at risk of developing internalizing and externalizing problems. Although some studies have analyzed the reasons for the use of discipline methods, little to no research has analyzed the moderating effects. In this study, we examine the relationship between maternal negative emotional expression and mothers' use of disciplinary methods (psychological aggression, corporal punishment and physical maltreatment) and the moderating effects of educational attainment in Chinese societies. Five hundred and sixteen mothers with preschool-aged children were recruited to participate in this research. The Chinese versions of the Self-Expressiveness in the Family Questionnaire (SEFQ) and the Parent-Child Conflict Tactics Scales (CTSPC) were used to measure the mothers' negative emotional expression and discipline, respectively. The results suggested that the mothers' negative emotional expression was positively related to their disciplinary behaviors. Moreover, maternal educational attainment moderated the association between negative emotional expression and discipline. The findings of the current study highlight the importance of considering how mothers' educational backgrounds may interact with their emotions to influence maternal disciplinary behaviors.
