Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Research on Scene-specific Pedestrian Detection Method Based on Deep Learning [PDF]
行人检测一直是计算机视觉中,尤其是目标检测领域的研究重点。而由于环境的时变性和多样性,不同场景之间样本不满足同分布,普通场景下训练得到的检测器直接应用到某一特定场景时性能会急剧下降。基于这样的背景,本文依据场景的复杂程度不同提出了两种对应的解决方法,主要工作和创新点如下: 1)当背景比较简单时,容易获取样本的标定信息,本文提出了一种快速的行人检测算法,首先基于结构化局部边缘模式计算样本特征,然后通过积分图技术快速计算分类器分数,从而使得检测过程更加高效 ...

Detection Algorithm Based on Consecutive FramesSubtraction and Codebook Model [PDF]
中文摘要:针对视频检测对实时性和准确性的要求, 提出了将帧间差分与码书模型相融合的运动目标检测算法。首先, 选取某个 t 时间内采集到的视频图像作为训练图像, 对图像的每一个像素点建立码书模型。把码书模型中表示前景的码书去除, 余下 的作为背景模型用于检测。检测运动目标时, 先将待检测的相邻帧图像进行帧间差分, 得到变化区域和没有变化的区域, 将 有变化的区域与背景模型进行拟合, 区分出前一帧运动区域和目标运动区域。更新背景模型时以不同的更新方法对前一帧 运动区域和目标运动区域进行更新。 英文摘要 ...

Climatic Long Term Trend and Prediction of the Wind Energy Resource in the Gwadar Port [PDF]
利用欧洲中期天气预报中心的ERA-Interim海表10m风场资料,计算巴基斯坦瓜达尔港的风能资源近36年(1979—2014年)期间的历史变化趋势,并利用线性回归和BP神经网络两种方法,对该港的风能资源进行长期年度预测,得到以下结果。1)瓜达尔港夏季的风能资源比冬季丰富,且夏季的稳定性明显好于冬季。2)近36年期间,风能密度、有效风速频率和100W/m2以上能级频率分别以?0.78W/(m2·a),?0.21%/a和?0.22%/a的速度逐年显著递减,且该趋势主要体现在夏季,冬季无显著变化趋势 ...

Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...
