Roboflow/trackers — это новая, унифицированная Python‑библиотека object‑tracking, в которой «с нуля» реализуются популярные алгоритмы многoобъектного трекинга (первым уже готов SORT, вскоре планируются Deep SORT, ByteTrack и др.)
Проект входит в open‑source‑экосистему Roboflow (Supervision, RF‑DETR и т.д.) и предоставляет единый API поверх разных детекторов, так что вы можете, например, скрестить Ultralytics YOLO‑v9, MMDetection или HuggingFace Transformers с любым трекером из пакета без «клея»‑оберток.
Установка pip install trackers
import supervision as sv from rfdetr import RFDETRBase # любой детектор from trackers.sort_tracker import SORTTracker
model = RFDETRBase() # или Ultralytics, MMDet… tracker = SORTTracker()
def callback(frame, _): dets = model.predict(frame) # сводим к sv.Detections dets = tracker.update(dets) # добавляем tracker_id return sv.LabelAnnotator( text_position=sv.Position.CENTER ).annotate(frame, dets, dets.tracker_id)
sv.process_video("in.mp4", "out.mp4", callback)
На выходе ‑ ролик с пронумерованными боксами, где каждый объект сохраняет ID между кадрами.
Лицензия без ограничений (Apache‑2.0) и возможность править алгоритм под себя.

The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram. At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. These entities are reportedly operating nine Telegram channels with more than five million subscribers to whom they were making recommendations on selected listed scrips. Such recommendations induced the investors to deal in the said scrips, thereby creating artificial volume and price rise. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” Overall, extreme levels of fear in the market seems to have morphed into something more resembling concern. For example, the Cboe Volatility Index fell from its 2022 peak of 36, which it hit Monday, to around 30 on Friday, a sign of easing tensions. Meanwhile, while the price of WTI crude oil slipped from Sunday’s multiyear high $130 of barrel to $109 a pop. Markets have been expecting heavy restrictions on Russian oil, some of which the U.S. has already imposed, and that would reduce the global supply and bring about even more burdensome inflation.
