The authors of the Embrapa WGISD: Embrapa Wine Grape Instance Segmentation Dataset aim to provide images and annotations for studying object detection and instance segmentation in viticulture for image-based monitoring and field robotics. The dataset includes instances from five different grape varieties captured in the field, exhibiting variations in grape pose, illumination, and focus, as well as genetic and phenological characteristics such as shape, color, and compactness.

The mentioned challenges of automation in agriculture, particularly in outdoor environments and uncertain plant structures, require advanced monitoring systems capable of fine-grained detection and localization of plant structures and fruits. Accurate fruit detection and localization are essential for various agricultural applications, including fruit counting, yield estimation, precision agriculture, disease monitoring, nutrient deficiency detection, and actuation tasks like automated spraying and harvesting.

Embrapa WGISD consists of 300 RGB images showcasing 4,432 grape clusters from five different grape varieties, as summarized in Table 1. The images were captured from a single winery, which employed dual pruning for shaping and production, resulting in canopies of lower density. The dataset represents real-world, trellis system-based wine grape production, and no specific intervention was performed for dataset construction. The camera captures frontal pose images, where the principal axis is approximately perpendicular to the wires of the trellis system and plant rows.

Total			300	4,432	2,020

The dataset provides binary masks for 2,020 clusters out of 4,432, used for supervised instance segmentation training.

The images were captured at the vineyards of Guaspari Winery in São Paulo, Brazil, with dual pruning performed by the winery staff. A Canon EOS REBEL T3i DSLR camera and a Motorola Z2 Play smartphone were used to capture the images. The cameras were positioned between the vine lines, facing the vines at distances of around 1-2 meters. The REBEL camera captured 240 images, including all Syrah pictures, while the Z2 smartphone captured 60 images covering all other varieties except Syrah. The REBEL images were scaled to 2048 × 1365 pixels, and the Z2 images were scaled to 2048 × 1536 pixels. More detailed information about the capture process can be found in the Exif data in the original image files, which are part of the dataset.

Summary #

Embrapa WGISD: Embrapa Wine Grape Instance Segmentation Dataset is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the agricultural industry.

The dataset consists of 300 images with 6451 labeled objects belonging to 2 different classes including uva_bbox and uva.

Images in the WGISD dataset have pixel-level instance segmentation and bounding box annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation task (only one mask for every class). All images are labeled (i.e. with annotations). There are 2 splits in the dataset: train (242 images) and test (58 images). Alternatively, the dataset could be split into 5 variety: cabernet franc (65 images), chardonnay (65 images), sauvignon blanc (65 images), cabernet sauvignon (57 images), and syrah (48 images). The dataset was released in 2019 by the Embrapa Agricultural Informatics, Brazil and Institute of Computing, University of Campinas, Brazil.

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
uva_bbox➔ rectangle	300	4432	14.77	18.65%
uva➔ mask	137	2019	14.74	11.41%

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.
