  • 融合传统算法与深度学习,自动识别树轮边界。
  • 自动检测准确率达81.0% F-score,手动修正量减少至20%。
  • 适合林业、气候研究等需高精度树轮分析的用户。

树轮标记是树木测量与树轮年代学的关键步骤,但通常依赖人工操作,耗时且主观,难以扩展到大规模图像数据集。本文提出开源图形化软件TRAS(Tree Ring Analyzer Suite),实现木本横截面图像中树轮的自动勾画、手动修正与测量。TRAS集成三种互补检测算法:经典图像处理方法CS-TRD及两种深度学习模型DeepCS-TRD和INBD。用户可通过界面修正自动检测结果,删除误检,手动补全缺失树轮。软件还计算早材/晚材面积、环周长、等效环宽及自定义路径环宽等树轮年代学指标。在18张经专家标注的Pinus taeda L. 横截面图像上评估,DeepCS-TRD表现最佳,F-score达81.0%,精确率为86.4%。自动检测使手动修正工作量降至约20%。一维环宽测量与CooRecorder高度一致(r > 0.99)。常见错误如跳跃传播或靠近节疤的假阳性,均可通过后处理界面轻松修正。TRAS支持Windows、macOS和Linux系统,代码已公开于https://hmarichal93.github.io/tras。

原文摘要 · Abstract (English)

Tree ring marking remains a key step in dendrometry and dendrochronology, but it is often performed manually, making the process time-consuming, subjective, and difficult to scale to large image datasets. We present the Tree Ring Analyzer Suite (TRAS), an open-source graphical software for automatic delineation, manual correction, and measurement of tree rings in wood cross-sectional images. TRAS integrates three complementary detection algorithms: the classical image-processing method CS-TRD and two deep-learning approaches, DeepCS-TRD and INBD. The interface allows users to refine automatic detections, remove false positives, and manually add missing rings. It also computes dendrochronological metrics such as earlywood and latewood areas, ring perimeter, equivalent ring width, and custom path-based ring-width measurements. TRAS was evaluated on 18 expertly annotated Pinus taeda L. cross-section images. DeepCS-TRD achieved the best automatic detection performance, with an F-score of 81.0% and precision of 86.4%. Automatic detection reduced the required manual correction effort to approximately 20% of ring boundaries. For one-dimensional ring-width measurements, TRAS showed excellent agreement with CooRecorder ($r > 0.99$). Common detection errors, such as jump propagation or false positives near knots, were easily corrected through the postprocessing interface. TRAS provides a flexible and reproducible solution for tree-ring analysis on Windows, macOS, and Linux. Code is available at the https://hmarichal93.github.io/tras.
