PKU-Market-PCB-corrected — LICENSE
===================================

This file covers TWO different things. Please read both parts.

--------------------------------------------------------------------------------
PART 1 — The modifications made in this release
--------------------------------------------------------------------------------

The changes made to produce "PKU-Market-PCB-corrected" are released under the

    Creative Commons Attribution 4.0 International License (CC BY 4.0)

Full legal text: https://creativecommons.org/licenses/by/4.0/legalcode

These modifications are:

  * removal of a stray images/data.yaml (a leftover single-class YOLO config),
  * conversion of the COCO annotations to Pascal VOC XML and YOLO TXT,
  * addition of a board-disjoint train/val split
    (train_board.txt 541 images / val_board.txt 152 images), alongside the
    upstream split (train.txt 555 / val.txt 138) which is preserved as-is,
  * regeneration of classes.txt, data.yaml, ImageSets/ and this documentation.

You are free to share and adapt these modifications for any purpose, including
commercially, provided you give appropriate credit.

--------------------------------------------------------------------------------
PART 2 — The underlying PKU-Market-PCB data (IMPORTANT)
--------------------------------------------------------------------------------

The underlying images and annotations originate from the PKU-Market-PCB dataset
(PCB defect dataset) released by the Open Lab on Human Robot Interaction,
Peking University:

    Huang, Weibo; Wei, Peng.
    "A PCB Dataset for Defects Detection and Classification."
    arXiv:1901.08204, 2019.
    https://arxiv.org/abs/1901.08204

    Official dataset page:
    https://robotics.pkusz.edu.cn/resources/dataset/

THE ORIGINAL AUTHORS HAVE NOT STATED A LICENSE FOR THE DATASET.

  * The dataset is offered for download from the authors' project page, and the
    associated paper is published on arXiv.
  * Neither the download page nor the paper grants an explicit licence for the
    image data or the annotations.
  * The dataset is described as synthesized from 10 standard template boards,
    with defects generated programmatically.

Consequently, the copyright status of the underlying PKU-Market-PCB images and
annotations is UNDETERMINED. No licence is granted for them by this file.

>>> Before any commercial use or redistribution of the image data, you must
>>> determine the applicable terms from the original authors.
