LogoDet-3K creates a more challenging benchmark for logo detection, for its higher comprehensive coverage and wider variety in both logo categories and annotated objects compared with existing datasets. \nThe statistic comparison of 9 super categories from LogoDet-3K is shown as follows,\n\n| Root Category | Sub-Category  | Images|Objects|\n| ------------- |:-------------:| -----:| -----:|\n| Food          |  932 |   53,350    | 64,276 |\n| Clothes       |  604 |   31,266    | 37,601 |\n| Necessities   |  432 |   24,822    | 30,643 |\n| Others        |  371 |   15,513    | 20,016 |\n| Electronic    |  224 |   9,675     | 12,139 |\n|Transportation |  213 |   10,445    | 12,791 |\n|Leisure        |  111 |   5,685     |  6,573 |\n|Sports         |  66  |   3,945     |  5,041 |\n|Medical        |  47  |   3,945     |  5,185 |\n|Total          |  3,000 |   158,652 |194,261 |\n\n## LogoDet-3K Dataset Detailed Statistics\nThe figure showns the detailed statistics of LogoDet-3K about Image and object distribution in per category, and the number\nof objects in per image and object size in per image.\n![example](logo/statistic.png)\n\nThe sorted distribution of images for each logo in LogoDet-3K is shown the figure. We can see that imbalanced distribution across\ndifferent logo categories are one characteristic of LogoDet-3K, posing a challenge for effective logo detection with few samples.\n![example](logo/statistic_histogram.png)\n\nThe figure shows the distributions of categories, images and objects from LogoDet-3K on super-classes.\n![example](logo/statistic_superclass.png)\n\n## Download Dataset Links\n\nServer link: 123.57.42.89/Dataset_ict/LogoDet-3K.zip\n\nBaidu Drive link: https://pan.baidu.com/share/init?surl=ECJ4zOurhMzBgDZ11ekxQA password:1234\n\n## Download pertrained model Links\n\nGoogle Drive link: https://drive.google.com/file/d/1GOYqRy7yoBVAt9Ih375NWtoZZTXN6OET/view?usp=sharing\n\n\n"
