morado_5may - Dataset Ninja

Introduction #

Stan Zwinkels, Ted de Vries Lentsch

All images that were taken in morado_5may: A Dataset for Detection of Ripe Flowers of the Alstroemeria Genus Morado show the top view of a flowerbed, and the camera was roughly 1.5 meters above the flowerbed. The images were taken with an iPhone 8, using the 12 MP camera creating images with a size of 4032x3024 pixels. The photos were taken on the 5th of May 2021 around twelve o’clock in the afternoon inside the greenhouse of Hoogenboom Alstroemeria company.

A cart that is normally used for harvesting flowers is equipped with a tripod to which the camera can be attached (camera at the location of the yellow circle). In this way, the camera is in the middle above the flowerbed. The cart is pushed along the flower bed and after about 1 meter of driving a picture is taken. The greenhouse has a total of 10 flowerbeds with Morado and all of them are recorded for the dataset. From each flowerbed, 41–43 pictures were taken. Some images may slightly overlap with each other at the borders. In total, the dataset consists of 414 images.

The dataset is unbalanced because the majority of the images contain much more raw flowers (not ripe) than ripe ones. Most of the images contain 1-3 ripe flowers, while there are always a dozen of raw flowers in an image.

Annotations in the dataset were applied to both fully and partially visible flowers, using two classes, namely (1) raw and (2) ripe, in addition to the background class. An Alstroemeria flower consists of several flower buds, and a cluster of these buds is considered as a flower. For each flower bud, a rectangle was drawn to precisely match the area of the flower. Each image contains around 10-20 flower buds, but typically only 1-3 of them are labeled as ripe. The ripeness classification of each flower is based on factors such as color, color uniformity, size, and the number of buds. A flower is considered ripe if it contains several buds starting to open, relatively large buds, and a bright purple color. These guidelines were established to help others identify misclassified flowers.

The full bud is bright purple so no yellow part halfway. A flower contains multiple buds that are starting to get open. The buds of the flower are large with respect to the buds of the other flowers.

The dataset exhibits several properties, including variation in illumination (due to changes in sunlight and shadows in the greenhouse), variation in size of ripe flowers, variation in the number of buds per ripe flower, some flowers being partially visible due to others, and a higher number of raw flowers compared to ripe ones. Furthermore, the ripeness classification of a flower is determined by multiple criteria, including color, color uniformity, size, and openness.

Summary #

morado_5may: A Dataset for Detection of Ripe Flowers of the Alstroemeria Genus Morado is a dataset for an object detection task. Possible applications of the dataset could be in the agricultural industry.

The dataset consists of 414 images with 5439 labeled objects belonging to 2 different classes including raw and ripe.

Images in the morado_5may dataset have bounding box annotations. All images are labeled (i.e. with annotations). There are no pre-defined train/val/test splits in the dataset. The dataset was released in 2021 by the Delft University of Technology, Netherlands and Hoogenboom Alstroemeria, Netherlands.

Class balance #

There are 2 annotation classes in the dataset. Find the general statistics and balances for every class in the table below. Click any row to preview images that have labels of the selected class. Sort by column to find the most rare or prevalent classes.

Rows 1-2 of 2

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
raw➔ rectangle	414	4679	11.3	5.99%
ripe➔ rectangle	335	760	2.27	2.02%

Co-occurrence matrix #

Co-occurrence matrix is an extremely valuable tool that shows you the images for every pair of classes: how many images have objects of both classes at the same time. If you click any cell, you will see those images. We added the tooltip with an explanation for every cell for your convenience, just hover the mouse over a cell to preview the description.

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Object distribution #

Interactive heatmap chart for every class with object distribution shows how many images are in the dataset with a certain number of objects of a specific class. Users can click cell and see the list of all corresponding images.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.

Rows 1-2 of 2

Class	Object count	Avg area	Max area	Min area	Min height	Min height	Max height	Max height	Avg height	Avg height	Min width	Min width	Max width	Max width
raw rectangle	4679	0.53%	2.44%	0.03%	51px	1.26%	584px	14.48%	240px	5.96%	55px	1.82%	729px	24.11%
