基于无人机遥感的黑龙江南瓮河国家级自然保护区驼鹿种群数量及空间分布调查
野生动物学报, 2023 2022年3月下旬，利用固定翼无人机对南瓮河国家级自然保护区内驼鹿（Alces alces）进行航拍调查，估算及分析保护区内驼鹿的种群数量、分布密度和生境因子之间的关系。结果表明：获取无人机影像17 818张，无人机样带拼接面积为206.9 km2。结合目视解译方式识别驼鹿并据此建立驼鹿无人机影像解译标志库。根据无人机样带解译结果，得到驼鹿的种群密度为（0.174±0.038）只/km2，估算出保护区驼鹿的种群数量为310~484只。驼鹿的分布及生境选择中生态因子的分析结果表明，驼鹿主要分布于海拔400~

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

Image enhancement method based on exposure fusion for UAV aerial photography
Xibei Gongye Daxue Xuebao, 2022 针对无人机航拍图像光照不均匀及自然雾导致影像质量退化问题, 提出了一种无人机航拍图像增强算法。利用改进的低照度图像增强算法均衡亮度对比度; 为了解决均衡后图像过增强问题, 提出了联合去雾及曝光融合的色彩矫正增强方法; 为了保留增强图像的边缘纹理信息, 设计了一种效果更佳的细节增强算法, 处理后统计直方图更为平滑, 可在一定程度上抑制部分噪声, 细节纹理信息更强。实验结果表明, 所提的航拍图像增强算法, 能够有效解决因光照不均或自然雾引起的影像退化现象, 提高了无人机航拍图像的质量 ...
