Introduction #

Released 2021-07-28 Β·Jian Zhang, Runwei Ding, Miaoju Banet al.

The MSD: Mobile Phone Defect Segmentation Dataset aims to alleviate the scarcity of data in the realm of industrial quality control. It comprises three distinct surface defect types: oil, scratch, and stain, with 400 images for each defect, totaling 1200 images. These images are captured using an industrial camera at a resolution of 1920Γ—1080 and follow the PASCAL VOC dataset format. Furthermore, the dataset includes 20 supplementary non-defective images, which can be valuable for unsupervised setting.

Surface defect detection stands as a common yet demanding task with the vital need for accuracy and real-time capabilities. Nonetheless, prevailing segmentation networks grapple with challenges related to defect boundary intricacies, local similarities among diverse defects, and the often meager contrast between defects and their background. Addressing these issues, the authors introduce FDSNet network both with the MSD dataset.

Summary #

MSD: Mobile Phone Defect Segmentation Dataset is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the surface defect detection domain.

The dataset consists of 1220 images with 3104 labeled objects belonging to 3 different classes including stain, oil, and scratch.

Images in the MSD 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 20 (2% of the total) unlabeled images (i.e. without annotations). There are no pre-defined train/val/test splits in the dataset. Additionally, images without defects are marked with good tag. The dataset was released in 2021 by the Peking University.

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.
