Supervisely Synthetic Crack Segmentation

Introduction #

Supervisely Synthetic Crack Segmentation is a dataset for a semantic segmentation of cracks in industrial inspection. Obtaining real-world annotated data for crack segmentation can be challenging. The detailed, pixel-perfect nature of segmentation requires extensive labor and often expert knowledge, making the process time-consuming and costly. Synthetic data offers a promising solution to these challenges. It provides a controlled, cost-effective, and automated alternative to real-world data collection and manual annotation.

Summary #

Supervisely Synthetic Crack Segmentation is a dataset for a semantic segmentation task. Possible applications of the dataset could be in the industrial domain.

The dataset consists of 1557 images with 1550 labeled objects belonging to 1 single class (cracks).

Images in the Supervisely Synthetic Crack Segmentation dataset have pixel-level semantic segmentation annotations. There are 7 (0% of the total) unlabeled images (i.e. without annotations). There are 2 splits in the dataset: synthetic cracks (1157 images) and synthetic cracks styled (400 images). The dataset was released in 2023 by the Supervisely.

Here is the visualized example grid with animated annotations:

Class balance #

There are 1 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 1-1 of 1

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
cracks➔ mask	1550	1550	1	2.21%

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.

Rows 1-1 of 1

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
cracks mask	1550	2.21%	10.71%	0.01%	16px	3.12%	512px	100%	351px	68.55%	19px	3.71%	512px	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 1550 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.
