Introduction #

Released 2017-07-23 Β·Petre Lameski, Eftim Zdravevski, Vladimir Trajkoviket al.

Weed detection from images has garnered substantial attention from scientific communities in recent years. However, there are only a few available datasets suitable for weed detection from unmanned and other ground vehicles and systems. Addressing mentioned issues, the authors introduce a new dataset named Carrot-Weed designed for weed detection under varying light conditions. This dataset comprises RGB images captured from young carrot seedlings throughout the month of February in the vicinity of Negotino, Republic of Macedonia. The authors conducted an initial analysis of the dataset and reported their preliminary findings, achieved through the utilization of convolutional neural network architectures.

Summary #

Carrot-Weed: Weed Detection Dataset with RGB Images Taken under Variable Light Conditions is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the agricultural research.

The dataset consists of 39 images with 745 labeled objects belonging to 2 different classes including weed and carrot.

Images in the Carrot-Weed dataset have pixel-level instance segmentation annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation (only one mask for every class) or object detection (bounding boxes for every object) tasks. 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 2017 by the University of Sts. Cyril and Methodius in Skopje, Macedonia.

Here is the visualized example grid with animated annotations:

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.
