Dataset Details

Dataset Description

The QMUL-OpenLogo dataset is a large-scale logo detection benchmark designed for evaluating open logo detection algorithms in realistic deployment scenarios. Unlike traditional logo detection datasets that assume exhaustive fine-grained labeling for all classes, QMUL-OpenLogo simulates real-world conditions where new logo classes arrive progressively and require detection with little or no labeled training data.

The dataset was created by aggregating and refining 7 existing logo detection datasets to establish a comprehensive benchmark for open logo detection. It contains 27,083 images across 352 logo classes, with a distinctive train/test split that designates only 32 classes as "supervised" (with labeled bounding boxes) while the remaining 320 classes are "unsupervised" (having only clean logo design images).

Dataset Structure

The QMUL-OpenLogo dataset follows a unique structure designed for open logo detection evaluation:

Original Format

The dataset aggregates 7 existing logo detection datasets:

FlickrLogos-27, FlickrLogos-32, Logo32plus, BelgaLogos, WebLogo-2M (test), Logo-In-The-Wild, SportsLogo

Key Statistics

Total images: 27,083
Logo classes: 352
Logo instances: Variable (10-1,902 per class, mean 88.25)
Scale variation: 0.0014%-100% of image area (mean 6.09%)
Highly imbalanced distribution: Significant variation in samples per class

Data Splits

The dataset uses a novel split designed for open logo detection:

Supervised Classes (32 classes):

Train: 1,280 images (40 per class from FlickrLogo32)
Val: 1,019 images
Test: 9,168 images
Logo designs: 32 clean design images (1 per class)

Unsupervised Classes (320 classes):

Train: 0 images (no labeled training data)
Val: 1,562 images
Test: 14,054 images
Logo designs: 320 clean design images (1 per class)

FiftyOne Dataset Structure

This dataset has been converted to FiftyOne format with the following fields:

filepath: Path to the image file
split: Train/val/test designation
supervision_level: "supervised" or "unsupervised" based on availability of labeled training data
width/height: Image dimensions
ground_truth: Detection objects with bounding boxes and labels
num_logos: Count of logos in the image
logo_classes: List of unique logo classes present

The FiftyOne dataset enables interactive visualization, filtering by supervision level, and analysis through the FiftyOne web interface.

Detailed technical information about the dataset creation methodology and evaluation protocol can be found in the accompanying research paper (1807.01964v3.pdf).

Dataset Creation

Curation Rationale

The QMUL-OpenLogo dataset was created to address a significant gap in existing logo detection benchmarks. Traditional benchmarks assume artificial deployment scenarios where large training datasets with fine-grained bounding box annotations are available for each class. However, in realistic logo detection scenarios, new logo classes come progressively and require detection with little or no budget for exhaustively labeling training data.

The dataset aims to provide a more realistic and challenging evaluation setting that better reflects real-world deployment constraints where scalability and adaptability to new classes are crucial.

Source Data

The source data consists of images from 7 existing publicly available logo detection datasets, carefully merged and refined to create a cohesive benchmark.

Data Collection and Processing

Source Dataset Integration: The following datasets were aggregated:

FlickrLogos-27 (27 classes, 810 images)
FlickrLogos-32 (32 classes, 2,240 images)
Logo32plus (32 classes, 7,830 images)
BelgaLogos (37 classes, 1,321 images)
WebLogo-2M Test only (194 classes, 4,318 images)
Logo-In-The-Wild (1,196 classes, 9,393 images)
SportsLogo (20 classes, 1,978 images)

Class Refinement Process:

Logo classes were made consistent across datasets (e.g., merging Adidas trefoil/text variations from LITW into single classes)
Erroneous annotations were cleaned (incorrect bounding box coordinates, size inconsistencies)
Classes with fewer than 10 images were removed to ensure sufficient test data
Manual verification of 1-3 random images per class was performed
Final result: 352 logo classes from 27,083 images

Who are the source data producers?

The original data producers are the creators of the 7 source datasets, representing diverse research groups and data collection efforts. The QMUL team performed the aggregation, refinement, and standardization process to create the unified benchmark.

Annotations

The dataset contains bounding box annotations inherited and refined from the source datasets.

Annotation process

The annotation process involved:

Integration: Combining annotations from multiple source datasets with varying formats
Standardization: Making logo class definitions consistent across datasets
Quality control: Removing erroneous annotations and verifying class labels
Clean-up: Filtering out classes with insufficient data (<10 images)
Validation: Manual verification of sample images per class

The annotations maintain the PASCAL VOC format for bounding boxes with class labels.

Who are the annotators?

The original annotations were created by the respective research teams for each source dataset. The QMUL team performed quality control, merging, and verification processes.

Personal and Sensitive Information

The dataset primarily focuses on commercial logos and brand imagery collected from existing research datasets. Considerations include:

Commercial imagery: Contains copyrighted logos and brand materials
Incidental content: May contain people, locations, or other identifiable information as part of the natural scene context
Web-sourced content: Some source datasets used web-collected imagery which may contain various types of content

No specific anonymization process is described. Users should be aware that aggregated web imagery may contain incidental personal or sensitive information.
