Global Wheat Head Detection (GWHD) Dataset: A Large and Diverse Dataset of High-Resolution RGB-Labelled Images to Develop and Benchmark Wheat Head Detection Methods

Figure 2

Examples of wheat heads difficult to label. These examples are zoomed-in views from images contained in the dataset, with different zoom factors. It includes overlapping heads (a–c), heads at emergence (d), heads that are partly cut at the border of the image (e), and images with a low illumination (f). Note that image (d) was removed from the dataset because of the ambiguity of heads at emergence. Wheat heads in the image (e) were not labelled because less than 30% of their basal part is visible, as defined in Section 2.4.
