Vietnamese Traffic Signs

Summary #

Vietnamese Traffic Signs Detection and Recognition Dataset is a dataset for an object detection task. It is used in the automotive industry.

The dataset consists of 1170 images with 2841 labeled objects belonging to 29 different classes including one way prohibition, speed limit, no parking, and other: intersection danger, indication, no stopping and parking, other prohibition, vehicle permission lane, road danger, direction, slow warning, no turn left, pedestrian danger, no truck entry/turning, no car entry/turning, pedestrian crossing, no motorbike entry/turning, no turn right, vehicle and speed permission lane, other warning, other, height limit, no u turn, no more prohibition, construction danger, no u and left turn, weight limit, no u and right turn, and overpass route.

Images in the Vietnamese Traffic Signs dataset have bounding box annotations. There are 6 (1% of the total) unlabeled images (i.e. without annotations). There are 3 splits in the dataset: train (900 images), val (180 images), and test (90 images). The dataset was released in 2023.

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.
