### What is this?

A **cleaned and standardized object-detection version** of the **PlantDoc** dataset
(Singh, Jain, Jain, Kayal, Kumawat & Batra — *"PlantDoc: A Dataset for Visual Plant Disease Detection"*,
[ACM CoDS-COMAD 2020](https://doi.org/10.1145/3371158.3371196), [arXiv:1911.10317](https://arxiv.org/abs/1911.10317);
upstream detection repo: [pratikkayal/PlantDoc-Object-Detection-Dataset](https://github.com/pratikkayal/PlantDoc-Object-Detection-Dataset)).

The original release is a web-scraped, hand-annotated benchmark. It contains **train/test leakage**
(identical images present in both splits), images without annotations, annotations without images,
class names with inconsistent spelling and casing, filenames polluted with URL query strings,
images whose downloaded resolution does not match the annotation canvas, and no validation split.

This release removes the leakage and the unusable records, normalizes all 29 class names, repairs
every filename and image-orientation inconsistency, provides a reproducible **train/val/test** split,
and ships ready-to-train **YOLO TXT** + **Pascal VOC XML** annotations with configuration files.

### Corrections vs. the official release

| # | Correction | Detail |
|---|---|---|
| 1 | **Removed train/test leakage** | 12 images were **byte-identical** copies present in *both* `TRAIN/` and `TEST/` (plus 16 further basename collisions). The duplicate training copy of each pair was removed, so the official test images are never seen during training. |
| 2 | **Normalized all 29 class names** | Upstream mixed styles: `Bell_pepper leaf` (underscore), `grape leaf` (lowercase), `Corn Gray leaf spot` (title case) and the typo `Soyabean leaf`. All names are now consistent Title Case (`Bell Pepper Leaf`, `Grape Leaf`, `Corn Gray Leaf Spot`, `Soybean Leaf`, …). |
| 3 | **Dropped 11 unannotated images** | Images present in the archive with **no** annotation XML at all (mostly thumbnails such as `...jpg?w=500&h=889`). |
| 4 | **Dropped 11 empty annotations** | Images whose XML contains **no** `<object>` — these carry no supervision and additionally break dataset indexing on Hugging Face. |
| 5 | **Dropped 4 unreconcilable images** | Downloaded as low-resolution thumbnails while annotated at original resolution, so their boxes lie outside the image frame (`Early-blight-example.ashx?mw=250`, `Fig 2b. GLS backlit copy`, `markjones-corn-001`, `powdery-mildew-on-squash-leaves.jpg?w=300&h=200`). Cannot be repaired without inventing coordinates. |
| 6 | **Removed 1 orphan annotation** | `TRAIN/NCLB.xml` has no matching image upstream (`NCLB.jpg` is absent from the archive). |
| 7 | **Filename hygiene** | 234 filenames contained URL encoding / query strings (`%20`, `+`, `?itok=`, `%253E`); 25 files had no extension at all and 12 carried web-script extensions (`.ashx`, `.aspx`, `.asp`, `.php`). All are percent-decoded, slugged to portable `[A-Za-z0-9._-]` names and given a correct `.jpg` / `.png`. Scraped SEO filenames running up to 215 characters (which break Windows checkout and are hostile everywhere) are truncated to ≤80 characters with an 8-hex-digit hash of the original name appended, so every renamed file stays traceable to its upstream name. |
| 8 | **EXIF orientation normalized** | 35 files carried an EXIF orientation tag while their annotations were authored against the *stored* pixel orientation. 30 had the orientation tag stripped **byte-level (pixels untouched)**; 5 whose annotations used the *EXIF-displayed* orientation had that rotation **baked into the pixels**. Result: the annotation canvas equals the stored pixel orientation for **every** loader (PIL, OpenCV, Ultralytics). |
| 9 | **Repaired `0×0` image sizes** | 4 VOC files declared `<width>0</width><height>0</height>`. The true pixel dimensions were written in, leaving coordinates untouched. |
| 10 | **Reproducible train/val/test split** | The official `TEST/` (236 images) is preserved as **test** for paper comparability; a stratified **10 %** validation set is carved out of `TRAIN/` (seed 42). |
| 11 | **Standard packaging** | Added `data.yaml`, `classes.txt`, synchronized dual-format annotations (`Annotations/` + `labels/`) and refreshed per-split CSV tables. |

All 8,887 bounding boxes are carried over unchanged — no coordinate was scaled, shifted or re-guessed.

### 这是什么？

**PlantDoc 植物病害数据集**（Singh 等，*ACM CoDS-COMAD 2020*，[arXiv:1911.10317](https://arxiv.org/abs/1911.10317)）的**目标检测清洗与标准化重构版**。上游检测版仓库为 [pratikkayal/PlantDoc-Object-Detection-Dataset](https://github.com/pratikkayal/PlantDoc-Object-Detection-Dataset)。

原始版本由网络爬取图片人工标注而成，存在大量数据质量缺陷：**训练/测试集数据泄漏**（同一张图同时出现在两个划分中）、有图无标注、有标注无图、类别名称大小写与拼写不统一（如 `Bell_pepper leaf`、`grape leaf`、拼写错误的 `Soyabean`）、文件名混入 URL 查询串、图片下载分辨率与标注画布不一致，且没有验证集。

本版本清除数据泄漏与不可用样本，统一 29 个类别名称，修复全部文件名与图片方向不一致问题，提供可复现的**训练/验证/测试**划分，并附带开箱即用的 **YOLO TXT** 与 **Pascal VOC XML** 双格式标注及训练配置。

> ✅ **上游许可证：CC BY 4.0**。本版沿用同一开源协议。

### 相对官方版的修正

| # | 修正项 | 说明 |
|---|---|---|
| 1 | **消除训练/测试数据泄漏** | 有 **12 张图片逐字节完全相同**却同时存在于 `TRAIN/` 与 `TEST/`（另有 16 组同名冲突）。本版删除每对中重复的训练副本，确保官方测试图绝不参与训练。 |
| 2 | **统一 29 个类别名称** | 上游命名混乱：`Bell_pepper leaf`（下划线）、`grape leaf`（小写）、`Corn Gray leaf spot`（首字母大写）以及拼写错误的 `Soyabean leaf`。现全部统一为 Title Case（`Bell Pepper Leaf`、`Grape Leaf`、`Corn Gray Leaf Spot`、`Soybean Leaf` 等）。 |
| 3 | **剔除 11 张无标注图片** | 压缩包中存在但**完全没有**标注 XML 的图片（多为 `...jpg?w=500&h=889` 之类的缩略图）。 |
| 4 | **剔除 11 个空标注** | XML 中**不含任何 `<object>`** 的图片——既无监督信息，又会导致 Hugging Face 数据集索引失败。 |
| 5 | **剔除 4 张无法修复的图片** | 下载到的是低分辨率缩略图，而标注按原图分辨率绘制，标注框落在图像范围之外（`Early-blight-example.ashx?mw=250`、`Fig 2b. GLS backlit copy`、`markjones-corn-001`、`powdery-mildew-on-squash-leaves.jpg?w=300&h=200`）。若不臆造坐标则无法修复。 |
| 6 | **移除 1 个孤立标注** | `TRAIN/NCLB.xml` 在上游无对应图片（`NCLB.jpg` 缺失）。 |
| 7 | **文件名净化** | 234 个文件名含 URL 编码/查询串（`%20`、`+`、`?itok=`、`%253E`）；25 个文件完全没有扩展名，另有 12 个带网页脚本扩展名（`.ashx`、`.aspx`、`.asp`、`.php`）。现全部百分号解码、规整为跨平台安全的 `[A-Za-z0-9._-]` 名称，并补上正确的 `.jpg` / `.png`。上游抓取网页留下的 SEO 长文件名最长可达 215 字符（会导致 Windows 检出失败，在任何平台都不友好），现统一截断至 ≤80 字符，并追加原文件名的 8 位十六进制哈希，确保每个改名文件仍可追溯到上游原名。 |
| 8 | **EXIF 方向归一化** | 35 个文件带有 EXIF 方向标签，而其标注是按**存储像素方向**绘制的。其中 30 个采用**字节级剥离方向标签（像素不变）**；5 个标注按**EXIF 显示方向**绘制的，则把该旋转**烘焙进像素**。最终无论用哪个框架读取（PIL / OpenCV / Ultralytics），标注画布都与存储像素方向一致。 |
| 9 | **修复 `0×0` 图像尺寸** | 4 个 VOC 文件声明 `<width>0</width><height>0</height>`，已写入真实像素尺寸，坐标保持不变。 |
| 10 | **可复现的训练/验证/测试划分** | 官方 `TEST/`（236 张）保留为 **test** 以便与论文对比；从 `TRAIN/` 中分层切出 **10%** 作为 **val**（随机种子 42）。 |
| 11 | **标准化打包** | 补充 `data.yaml`、`classes.txt`、双格式同步标注（`Annotations/` + `labels/`）以及按划分刷新的 CSV 表格。 |

全部 **8,887 个标注框**均为原样迁移——没有任何坐标被缩放、平移或重新臆测。

	Every image has exactly one YOLO `.txt` and one VOC `.xml`; there are no empty label files.

	### Quick Start (Ultralytics YOLO)

	```bash
	yolo detect train data=data.yaml model=yolov8n.pt epochs=100 imgsz=640

	### 这是什么？

	PlantDoc 植物病害数据集（Singh 等，ACM CoDS-COMAD 2020，[arXiv:1911.10317](https://arxiv.org/abs/1911.10317)）的目标检测清洗与标准化重构版。上游检测版仓库为 [pratikkayal/PlantDoc-Object-Detection-Dataset](https://github.com/pratikkayal/PlantDoc-Object-Detection-Dataset)。

	原始版本由网络爬取图片人工标注而成，存在大量数据质量缺陷：训练/测试集数据泄漏（同一张图同时出现在两个划分中）、有图无标注、有标注无图、类别名称大小写与拼写不统一（如 `Bell_pepper leaf`、`grape leaf`、拼写错误的 `Soyabean`）、文件名混入 URL 查询串、图片下载分辨率与标注画布不一致，且没有验证集。

	本版本清除数据泄漏与不可用样本，统一 29 个类别名称，修复全部文件名与图片方向不一致问题，提供可复现的训练/验证/测试划分，并附带开箱即用的 YOLO TXT 与 Pascal VOC XML 双格式标注及训练配置。

	> ✅ 上游许可证：CC BY 4.0。本版沿用同一开源协议。

	### 相对官方版的修正

	\| # \| 修正项 \| 说明 \|
	\|---\|---\|---\|
	\| 1 \| 消除训练/测试数据泄漏 \| 有 12 张图片逐字节完全相同却同时存在于 `TRAIN/` 与 `TEST/`（另有 16 组同名冲突）。本版删除每对中重复的训练副本，确保官方测试图绝不参与训练。 \|
	\| 2 \| 统一 29 个类别名称 \| 上游命名混乱：`Bell_pepper leaf`（下划线）、`grape leaf`（小写）、`Corn Gray leaf spot`（首字母大写）以及拼写错误的 `Soyabean leaf`。现全部统一为 Title Case（`Bell Pepper Leaf`、`Grape Leaf`、`Corn Gray Leaf Spot`、`Soybean Leaf` 等）。 \|
	\| 3 \| 剔除 11 张无标注图片 \| 压缩包中存在但完全没有标注 XML 的图片（多为 `...jpg?w=500&h=889` 之类的缩略图）。 \|
	\| 4 \| 剔除 11 个空标注 \| XML 中不含任何 `<object>` 的图片——既无监督信息，又会导致 Hugging Face 数据集索引失败。 \|
	\| 5 \| 剔除 4 张无法修复的图片 \| 下载到的是低分辨率缩略图，而标注按原图分辨率绘制，标注框落在图像范围之外（`Early-blight-example.ashx?mw=250`、`Fig 2b. GLS backlit copy`、`markjones-corn-001`、`powdery-mildew-on-squash-leaves.jpg?w=300&h=200`）。若不臆造坐标则无法修复。 \|
	\| 6 \| 移除 1 个孤立标注 \| `TRAIN/NCLB.xml` 在上游无对应图片（`NCLB.jpg` 缺失）。 \|
	\| 7 \| 文件名净化 \| 234 个文件名含 URL 编码/查询串（`%20`、`+`、`?itok=`、`%253E`）；25 个文件完全没有扩展名，另有 12 个带网页脚本扩展名（`.ashx`、`.aspx`、`.asp`、`.php`）。现全部百分号解码、规整为跨平台安全的 `[A-Za-z0-9._-]` 名称，并补上正确的 `.jpg` / `.png`。上游抓取网页留下的 SEO 长文件名最长可达 215 字符（会导致 Windows 检出失败，在任何平台都不友好），现统一截断至 ≤80 字符，并追加原文件名的 8 位十六进制哈希，确保每个改名文件仍可追溯到上游原名。 \|
	\| 8 \| EXIF 方向归一化 \| 35 个文件带有 EXIF 方向标签，而其标注是按存储像素方向绘制的。其中 30 个采用字节级剥离方向标签（像素不变）；5 个标注按EXIF 显示方向绘制的，则把该旋转烘焙进像素。最终无论用哪个框架读取（PIL / OpenCV / Ultralytics），标注画布都与存储像素方向一致。 \|
	\| 9 \| 修复 `0×0` 图像尺寸 \| 4 个 VOC 文件声明 `<width>0</width><height>0</height>`，已写入真实像素尺寸，坐标保持不变。 \|
	\| 10 \| 可复现的训练/验证/测试划分 \| 官方 `TEST/`（236 张）保留为 test 以便与论文对比；从 `TRAIN/` 中分层切出 10% 作为 val（随机种子 42）。 \|
	\| 11 \| 标准化打包 \| 补充 `data.yaml`、`classes.txt`、双格式同步标注（`Annotations/` + `labels/`）以及按划分刷新的 CSV 表格。 \|

	全部 8,887 个标注框均为原样迁移——没有任何坐标被缩放、平移或重新臆测。
