Sometimes we need to use curl/wget to download files from Google Drive from scripts. In terms of small file, we don't have any issues, but on the other hand, with a big file(especially download pre-trained model) needs to download the file manually which is very annoyed.
In this my last post in 2019, I'll show you how to avoid downloading files manually.
Beyond scale variation, appearance-complexity variation should be considered too for the object detection task, due to that the object instances with similar size can be quite different.
To solve this, we extend multi-scale detection fashions with a new dimension: multi-level. Deeper level learns features for objects with more appearance-complexity variation(e.g., pedestrian), while shallower level learns features for more simplistic objects(e.g., traffic light).
1, We propose Multi Level FPN:
2, Based on MLFPN, we propose a single-shot object detector: M2Det, which represents the Multi-Level Multi-Scale Detector.
Methodology:
a. Construct the base feature:
We use the output of FFMv1(Feature Fusion Module v1) to construct the base feature. The size is fixed as…
