对比ResNet与Inception在野生动物检测中的表现,发现Inception略胜一筹。
Evaluation of deep learning architectures for wildlife object detection: A comparative study of ResNet and Inception
- 用ResNet-101和Inception v3分别提取特征,标准化预处理后训练
- Inception v3达95%准确率和0.92 mAP,优于ResNet-101的94%与0.91
- 适合关注野生动物监测的生态与计算机视觉研究者参考
野生动物目标检测在生物多样性保护、生态监测和栖息地保护中具有重要作用。然而,环境变化、物种间视觉相似性以及类内差异常带来挑战。本研究在复杂条件下评估了两种深度学习架构——ResNet-101与Inception v3在野生动物目标检测中的有效性。模型在野生动物图像数据集上训练与评估,采用统一预处理:将图像最大尺寸缩放至800像素,转为RGB格式,并转换为PyTorch张量。训练与验证按70:30比例划分。ResNet-101取得94%分类准确率和0.91 mAP,展现出强大的深层层次特征提取能力;Inception v3表现更优,达到95%准确率和0.92 mAP,归因于其通过并行卷积实现的高效多尺度特征提取。尽管两者在视觉相似物种或弱光、遮挡情况下的检测仍存在困难,但结果证实,二者均为野生动物目标检测任务的有效模型,可为面向保护的计算机视觉应用提供可靠基础。
原文摘要 · Abstract (English)
Wildlife object detection plays a vital role in biodiversity conservation, ecological monitoring, and habitat protection. However, this task is often challenged by environmental variability, visual similarities among species, and intra-class diversity. This study investigates the effectiveness of two individual deep learning architectures ResNet-101 and Inception v3 for wildlife object detection under such complex conditions. The models were trained and evaluated on a wildlife image dataset using a standardized preprocessing approach, which included resizing images to a maximum dimension of 800 pixels, converting them to RGB format, and transforming them into PyTorch tensors. A ratio of 70:30 training and validation split was used for model development. The ResNet-101 model achieved a classification accuracy of 94% and a mean Average Precision (mAP) of 0.91, showing strong performance in extracting deep hierarchical features. The Inception v3 model performed slightly better, attaining a classification accuracy of 95% and a mAP of 0.92, attributed to its efficient multi-scale feature extraction through parallel convolutions. Despite the strong results, both models exhibited challenges when detecting species with similar visual characteristics or those captured under poor lighting and occlusion. Nonetheless, the findings confirm that both ResNet-101 and Inception v3 are effective models for wildlife object detection tasks and provide a reliable foundation for conservation-focused computer vision applications.
