Introduction #
The Coffee Leaf Biotic Stress dataset asserts that biotic stress involves plant damage inflicted by living organisms. Effectively managing biotic agents, such as pests and pathogens (viruses, fungi, bacteria, etc.), is intricately linked to the concept of agricultural sustainability. Agricultural sustainability advocates for the development of new technologies to minimize environmental impacts, enhance accessibility for farmers, and consequently, boost productivity. Leveraging computer vision with deep learning methods enables the timely and accurate identification of stress-inducing agents. Thus, corrective measures can be promptly implemented to mitigate the issue. The goal of this initiative is to devise an efficient and practical system capable of identifying and assessing the severity of stress caused by biotic agents on coffee leaves.
Summary #
Deep Learning for Classification and Severity Estimation of Coffee Leaf Biotic Stress is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the agricultural industry, and in the biological research.
The dataset consists of 500 images with 2977 labeled objects belonging to 2 different classes including leaf and symptom.
Images in the Coffee Leaf Biotic Stress 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 3 splits in the dataset: Train (400 images), Test (50 images), and Val (50 images). The dataset was released in 2019 by the Federal University of Espírito Santo, Brazil.
Here is the visualized example grid with animated annotations:
Explore #
Coffee Leaf Biotic Stress dataset has 500 images. Click on one of the examples below or open "Explore" tool anytime you need to view dataset images with annotations. This tool has extended visualization capabilities like zoom, translation, objects table, custom filters and more. Hover the mouse over the images to hide or show annotations.
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.
Class ㅤ | Images ㅤ | Objects ㅤ | Count on image average | Area on image average |
---|---|---|---|---|
leaf➔ mask | 500 | 500 | 1 | 31.63% |
symptom➔ mask | 400 | 2477 | 6.19 | 1.61% |
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.
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 |
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
symptom mask | 2477 | 0.26% | 5.69% | 0% | 1px | 0.1% | 565px | 55.18% | 70px | 6.88% | 1px | 0.05% | 1078px | 52.64% |
leaf mask | 500 | 31.63% | 47.45% | 17.18% | 448px | 43.75% | 1024px | 100% | 666px | 65.01% | 1293px | 63.13% | 2048px | 100% |
Spatial Heatmap #
The heatmaps below give the spatial distributions of all objects for every class. These visualizations provide insights into the most probable and rare object locations on the image. It helps analyze objects' placements in a dataset.
Objects #
Table contains all 2977 objects. Click a row to preview an image with annotations, and use search or pagination to navigate. Sort columns to find outliers in the dataset.
