CorStitch自动化拼接水下珊瑚监测视频，开源易用。
CorStitch: Accessible Video Stitching for Coral Monitoring
- 用傅里叶图像配准法拼接连续帧的水平条带。
- 生成的拼接图质量与现有软件相当，支持地理标记。
- 适合非专业用户、社区组织和环保机构使用。
我们开发了CorStitch，一款用于珊瑚礁监测与评估的视频拼接软件。该软件自动化处理俯视带状样方和潜水样线的水下视频，采用基于傅里叶的图像配准算法，拼接连续帧的中心水平条带，生成地理参考并标记的全景图。测试表明，CorStitch生成的全景图质量与现有软件相当，且具有开源、易用的优势，适用于不同技术背景的用户。该工具有望补充当地社区、政府机构及非政府组织的珊瑚礁监测工作。
原文摘要 · Abstract (English)
We develop CorStitch, a video-stitching software that automates the process of stitching underwater videos for coral reef monitoring and assessment. It offers a free, flexible, and user-friendly alternative to existing stitching software that may be difficult to access. CorStitch utilizes a Fourier-based image registration algorithm to stitch the central horizontal strips of successive frames of down-looking belt and dive transect videos, generating georeferenced and marked mosaics. Tests show that CorStitch can produce high-quality mosaics that are comparable to those generated by existing stitching software, with the added advantage of being open-source and accessible to users with varying levels of technical expertise. CorStitch has the potential to supplement the coral reef monitoring efforts of local communities, government agencies, and non-governmental organizations.
