Introduction #

Pankaj Mishra, Riccardo Verk, Daniele Fornasieret al.

The authors of the BTAD: beanTech Anomaly Detection dataset introduce a novel transformer-based image anomaly detection and localization network VT-ADL. The BTAD dataset comprises real-world industrial anomaly data and consists of RGB images depicting three distinct industrial products. product_1 features images with dimensions of 1600×1600 pixels, product_2 with 600×600 pixels, and product_3 with 800 × 600 pixels. Training data for Products 1, 2, and 3 comprises 400, 1000, and 399 images, respectively. During training, all images are initially scaled to a size of 512 pixels. For each anomalous image, a pixel-wise ground truth mask is meticulously provided.

In the realm of computer vision, anomalies refer to any image or image segment that exhibits significant deviations from predefined normal characteristics. Anomaly detection involves identifying these novel samples, either through supervised or unsupervised methods. There is a considerable demand for intelligent anomaly detection systems, given their wide-ranging applications, spanning from video surveillance and defect segmentation to quality control, medical imaging, and financial transaction monitoring. Notably, anomaly detection holds particular significance in the industrial sector, where it can facilitate the automated identification of defective products.

Summary #

BTAD: beanTech Anomaly Detection Dataset is a dataset for instance segmentation, semantic segmentation, object detection, and semi supervised learning tasks. It is used in the manufacturing industry, and in the anomaly detection research.

The dataset consists of 2540 images with 691 labeled objects belonging to 3 different classes including product_2, product_1, and product_3.

Images in the BTAD 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. There are 2261 (89% of the total) unlabeled images (i.e. without annotations). There are 2 splits in the dataset: train (1799 images) and test (741 images). Alternatively, the dataset could be split into 2 image sets: ok (2250 images) and ko (290 images). The dataset was released in 2021 by the beanTech, Italy and University of Udine, Italy.

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.
