Motorcycle Night Ride - Dataset Ninja

Introduction #

Sadhli Roomy, Mominul Islam, Abu Bakar Siddik Nayemet al.

The Motorcycle Night Ride Dataset is a collection of 200 frames taken from open media available on YouTube to enable testing for object detection and/or mobility-centered AI solutions - especially on motorcycle helmets with computer vision or other inventive avenues. Developing a dataset can be challenging given the cost of collection and labeling. Acme AI recognizes this bottleneck and is therefore creating open datasets for AI researchers, enthusiasts, and start-ups - enabling them to test their ideas.

Source data was collected from open media - particularly a video of the WatermelonMotoHead channel on YouTube. This particular dataset was a night scene named Harley Davidson 48 Night Ride which is based on a cruise in Tucson, Arizona, USA. The dataset is captured during night-time and therefore is subject to artifacts. The authors have used SuperAnnotate’s pixel editor as the tool for the semantics segmentation. It works on a raster logic as opposed to a vector one. Exporting includes the COCO format. They have prepackaged the dataset inclusive of fused images.

Summary #

Motorcycle Night Ride is a dataset for instance segmentation, semantic segmentation, and object detection tasks. It is used in the automotive industry.

The dataset consists of 200 images with 10697 labeled objects belonging to 6 different classes including rider, my bike, road, and other: undrivable, lane mark, and moveable.

Images in the Motorcycle Night Ride dataset have pixel-level instance segmentation and bounding box annotations. Due to the nature of the instance segmentation task, it can be automatically transformed into a semantic segmentation task (only one mask for every class). All images are labeled (i.e. with annotations). There are no pre-defined train/val/test splits in the dataset. The dataset was released in 2023 by the ACME Technologies Ltd., Bangladesh.

Here are the visualized examples for the classes:

Explore #

Motorcycle Night Ride dataset has 200 images. Click on one of the examples below or open "Explore" tool anytime you need to view dataset images with annotations. This tool has extended visualization capabilities like zoom, translation, objects table, custom filters and more. Hover the mouse over the images to hide or show annotations.

Class balance #

There are 6 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 1-6 of 6

Class ㅤ	Images ㅤ	Objects ㅤ	Count on image average	Area on image average
undrivable➔ any	200	529	2.65	70.58%
road➔ any	200	3623	18.11	63.91%
rider➔ any	200	628	3.14	35.2%
my bike➔ any	200	437	2.19	30.1%
lane mark➔ any	197	2719	13.8	35.4%
moveable➔ any	190	2761	14.53	7.37%

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.

Rows 1-6 of 6

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 #
