Wild Berry image dataset collected in Finnish forests and peatlands using drones

Introduction

Berry picking has long-standing traditions in Finland, yet it is challenging and can potentially be dangerous. The integration of drones equipped with advanced imaging techniques represents a transformative leap forward, optimising harvests and promising sustainable practices. We propose WildBe, the first image dataset of wild berries captured in peatlands and under the canopy of Finnish forests using drones. Unlike previous and related datasets, WildBe in- cludes new varieties of berries, such as bilberries, cloudberries, lingonberries, and crowberries, captured under severe light variations and in cluttered environments. WildBe features 3,516 images, including a total of 18,468 annotated bounding boxes.

How to use: an example of visualization

import json
import numpy as np
from datasets import load_dataset
from PIL import Image, ImageDraw
# Color map for classes
classes_color_map = {
    0: (225,15,10),
    1: (40, 150, 210),
    2: (10,0,210),
    3: (130,5,125),
}
# Load the dataset
dataset = load_dataset("FBK-TeV/WildBe", split="validation")
#Read first image and its lables
image_bytes = dataset[0]["image"]
np_image = np.frombuffer(image_bytes, dtype=np.uint8)
np_image = np_image.reshape(dataset[0]["image_height"], dataset[0]["image_width"], 3)
image = Image.fromarray(np_image)
labels = json.loads(dataset[0]["labels"])
draw = ImageDraw.Draw(image)
#Draw lables
for label in labels:
    center_x = label["x"] * dataset[0]["image_width"]
    center_y = label["y"] * dataset[0]["image_height"]
    width = label["width"] * dataset[0]["image_width"]
    height = label["height"] * dataset[0]["image_height"]
    draw.rectangle(
        [
            (center_x - width / 2, center_y - height / 2),
            (center_x + width / 2, center_y + height / 2),
        ],
        outline=classes_color_map[label["class"]],
        width=2,
    )
image.show()
