ToF相机的有效深度数据提取与校正算法研究

open access: yes智能科学与技术学报, 2020
提出一种针对 ToF 相机的有效深度数据提取与校正算法,利用深度图和置信度图对深度信息进行校正。首先,基于核密度估计和连通域标记对测得的深度图进行自适应分割;然后使用一种改进的结构张量进行边缘检测,从而探测深度图中的无效像素和飞行像素;最后用双三次方插值或投票操作纠正或剔除这些像素,同时使用增强置信度剔除错误像素。实验结果证明了该算法的有效性,对比传统方法,本文所提算法可以剔除更多的无效像素,且保留更多的有效深度数据,对于噪声的鲁棒性也更好。

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

太阳活动区EUV图像的生成式模型耀斑分级与预报

open access: yesKongjian kexue xuebao, 2023
近年来,不断发射的空基观测台持续传送回海量日面图像及日地间气象数据,为采用人工智能技术对太阳活动进行预报预警提供了数据基础。但是,极端天气爆发少,样本量较少;中等程度爆发稍多,样本量较多;常规无爆发天气常见,样本较为集中,样本不均衡状况严重影响机器学习方法在空间天气领域的广泛应用。本文面向多源多通道多尺度日面图像信息,构建了来自SOHO和SDO的1996-2015年日面活动区图像数据集;针对数据分布的不平衡,对太阳活动区图像作耀斑分级与预报。在对比分析元学习算法的基础上 ...

A Systematic Review on Generative AI in L2 Speaking Development From a Self‐Determination Theory Perspective

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Second or foreign language (L2) speaking is a key aspect of L2 competence. While GenAI shows potential to address challenges in L2 speaking development, its role remains insufficiently understood. Self‐Determination Theory (SDT) could explain student language learning engagement. Therefore, this systematic review examines how GenAI affordances

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
