Introduction #

Javier Silvestre-Blanes, Teresa Albero-Albero, Ignacio Miralleset al.

The authors of the AFID: A Public Fabric Image Database for Defect Detection discuss the challenges in developing and comparing methods for detecting and classifying defects in the textile industry. They highlight the lack of a suitable public annotated benchmark, which makes it difficult for researchers to evaluate and compare various defect detection methods effectively. To address this issue, they aim to create a comprehensive collection of images with and without defects and make them publicly available for research and comparison purposes. The database consists of 245 images of 7 different fabrics. There are 140 defect-free images, 20 for each type of fabric. With different types of defects, there are 105 images. Images have a size of 4096×256 pixels.

Defect detection in the textile industry is essential for reducing costs and improving customer satisfaction. Over the past two decades, numerous methods and algorithms for textile defect detection have been proposed. However, comparing the results of these methods is challenging due to variations in image properties, defect types, and image resolution across different studies.

To support their research work, the authors have created a collection of samples with and without defects. This collection includes images obtained from a factory environment over a period of six months. The defects present in these images are described, and the authors note that they contain the most common types of defects found in factories, providing a valuable resource for the development and evaluation of defect detection methods.

Summary #

AFID: A Public Fabric Image Database for Defect Detection is a dataset for instance segmentation, semantic segmentation, object detection, and classification tasks. It is used in the textile industry, and in the surface defect detection domain.

The dataset consists of 247 images with 117 labeled objects belonging to 12 different classes including fuzzyball, nep, broken end, and other: broken pick, cut selvage, broken yarn, crease, warp ball, weft curling, knots, contamination, and weft crack.

Images in the AFID 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 145 (59% of the total) unlabeled images (i.e. without annotations). There are no pre-defined train/val/test splits in the dataset. Alternatively, the dataset could be split into 2 classification image sets: no defect (141 images) and defect (106 images). Additionally, fabric code information is provided. The dataset was released in 2019 by the Universitat Politècnica de València, Spain and AITEX, Spain.

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.
