Although a live audience was planned and tickets for the event were sold, such plans were hastily cancelled after a spike in COVID-19 cases in Romania. However, after Swedish authorities refused to cooperate with Valve, the company was forced to move the event to Romania. As a result, Valve delayed the event to August 2021 at the same venue. However, the COVID-19 pandemic and lockdowns that followed made it impossible to hold the tournament. The International 10 was originally scheduled to be held in August 2020 at the Avicii Arena in Stockholm, Sweden. ![]() The event's Grand Final also became the third ever to feature five games, after the 20 editions. PSG.LGD became the fifth team to reach the Grand Finals more than once, after Natus Vincere, OG, Team Liquid and Newbee, and the second team to lose more than one Grand Finals after Natus Vincere. ![]() Team Spirit became the second Eastern European team to win the championship after Natus Vincere, which won the championship in 2011. The International 10 became the fourth consecutive event won by a European team. 2021 marks the sixth consecutive year that The International's prize pool outgrows its previous record. The majority of the money awarded during the event is collected through several in-game items released by Valve, including the The International 10 Battle Pass, a digital tournament pass and features bundle tied to the event that included many activities and cosmetic items. With a prize pool of over US$40 million, The International 10 is the largest tournament to ever take place in eSports, breaking the record held by its predecessor, which awarded $34 million. The tournament began on 7 October 2021 with the Group Stage and closed on 17 October 2021 with the Grand Finals, where Team Spirit became champions after defeating PSG.LGD in the Grand Finals. Hosted by Valve Corporation, it took place at the National Arena in Bucharest, Romania. Test-challenge contains 6,053 images and 1,090,637 instances.The International 2021 (originally named The International 2020) was the tenth iteration of Dota 2's flagship annual championship. We released the images but not the ground truths. Test-dev contains 2,792 images and 353,346 instances. We released the images and ground truths for training and validation sets. Validation contains 593 images and 81,048 instances. Training contains 1,830 images and 268,627 instances. Furthermore, we have two test sets, namely test-dev and test-challenge. To avoid the problem of overfitting, the proportion of training and validation set is smaller than the test set. The 11,268 images of DOTA are split into training, validation, test-dev, and test-challenge sets. Compared to DOTA-v1.5, it further adds the new categories of ”airport” and ”helipad”. There are 18 common categories, 11,268 images and 1,793,658 instances in DOTA-v2.0. This version was released for the DOAI Challenge 2019 on Object Detection in Aerial Images in conjunction with IEEE CVPR 2019.ĭOTA-v2.0 collects more Google Earth, GF-2 Satellite, and aerial images. The number of images and dataset splits are the same as DOTA-v1.0. Moreover, a new category, ”container crane” is added. The proportions of the training set, validation set, and testing set in DOTA-v1.0 are 1/2, 1/6, and 1/3, respectively.ĭOTA-v1.5 uses the same images as DOTA-v1.0, but the extremely small instances (less than 10 pixels) are also annotated. Now it has three versions:ĭOTA-v1.0 contains 15 common categories, 2,806 images and 188, 282 instances. We will continue to update DOTA, to grow in size and scope to reflect evolving real-world conditions. The instances in DOTA images are annotated by experts in aerial image interpretation by arbitrary (8 d.o.f.) quadrilateral. Each image is of the size in the range from 800 × 800 to 20,000 × 20,000 pixels and contains objects exhibiting a wide variety of scales, orientations, and shapes. The images are collected from different sensors and platforms. It can be used to develop and evaluate object detectors in aerial images. ![]() DOTA is a large-scale dataset for object detection in aerial images. ![]()
