Introduction #
The LogoDet-3K: A Large-Scale Image Dataset for Logo Detection is a significant contribution to the logo detection, with broad applications in multimedia such as copyright infringement detection, brand visibility monitoring, and product brand management on social media. It features 3,000 logo categories, approximately 200,000 manually annotated logo objects, and 158,652 images, sets a new standard for logo detection benchmarks. The authors detail the dataset construction process, including logo image collection, filtering, and object annotation. The dataset is divided into nine super-classes based on daily life needs and common enterprise positioning.
For the construction of LogoDet-3K, the authors followed a meticulous three-step process, involving logo image collection, logo image filtering, and logo object annotation. Each image was thoroughly examined and reviewed to ensure the dataset’s quality after filtering and annotation.
Logo image collection
During the phase, it was compiled a comprehensive logo list based on various reputable sources, resulting in a vocabulary of 3,000 logo names spanning nine super-classes: sports, leisure, transportation, food, electronic, necessities, clothes, medical, others. Images were then retrieved from search engines using these names as queries. The dataset creation process involved manual cleaning and filtering to ensure data quality, including the removal of images with unsuitable sizes or extreme aspect ratios and those without logos.
| Root Category | Sub-Category | Images | Objects |
|---|---|---|---|
| Food | 932 | 53,350 | 64,276 |
| Clothes | 604 | 31,266 | 37,601 |
| Necessities | 432 | 24,822 | 30,643 |
| Others | 371 | 15,513 | 20,016 |
| Electronic | 224 | 9,675 | 12,139 |
| Transportation | 213 | 10,445 | 12,791 |
| Leisure | 111 | 5,685 | 6,573 |
| Sports | 66 | 3,945 | 5,041 |
| Medical | 47 | 3,945 | 5,185 |
| Total | 3,000 | 158,652 | 194,261 |
Logo object annotation
During the process a considerable amount of time was required. The resulting LogoDet-3K dataset consists of 3,000 logo classes, 158,652 images, and 194,261 logo objects. The dataset exhibits imbalanced distributions across different logo categories, presenting a challenge for effective logo detection, particularly for categories with fewer samples. The statistics at the superclass and category levels illustrate this imbalance.

Additionally, the authors provide insights into the distribution of images and categories in LogoDet-3K, highlighting the challenges posed by imbalances across different logo objects and images. The dataset is characterized by a large percentage of small and medium logo objects, creating additional challenges for logo detection, as smaller logos are inherently harder to detect.

The dataset’s statistics further detail the distribution of logo categories, images, and logo objects across nine super-classes, revealing variations in sizes and numbers. Notably, the Food, Clothes, and Necessities classes exhibit larger numbers of objects and images compared to other classes in the dataset.

KaggleSummary #
LogoDet-3K is a dataset for an object detection task. It is used in the retail industry.
The dataset consists of 158654 images with 194261 labeled objects belonging to 3000 different classes including lexus-1, avery_dennison-2, alpinestars-2, and other: new_balance-1, 76, maybach-1, mclaren, lexus-2, kichesippi-2, zendium, yuyue-2, nongfu_spring-2, longmu-1, longmu-2, square_one_organic, steeden, neil_pryde-2, new_balance-2, tiffany, kichesippi-1, yuyue-1, auxx-2, chow_tai_seng-1, thomapyrin, kleenex, jus-rol, paralen, music_man-2, and 2972 more.
Images in the LogoDet-3K dataset have bounding box annotations. There are 4 (0% of the total) unlabeled images (i.e. without annotations). There are no pre-defined train/val/test splits in the dataset. Alternatively, the dataset could be split into 9 root-categories: food (53350 images), clothes (31266 images), necessities (24822 images), others (15513 images), transportation (10445 images), electronic (9675 images), leisure (5685 images), sports (3953 images), and medical (3945 images). The dataset was released in 2020 by the Shandong Normal University, China and Chinese Academy of Sciences.
