Activity Recognition Datasets

An overview of recent action recognition datasets and their detection classes

Concepts & terminologies:

Action: Atomic low-level movement such as standing up, sitting down, walking, talking etc.
Activity/event: Higher level occurence then actions such as dining, playing, dancing
Trimmed video: A short video clip containing event/action/activity of interest
Untrimmed video: A video clip of arbitrary length potentially containing durations without activities of interest
Localization: locating an instance of event/action/activity within a video at a spatial or temporal scale
Spatial localization: Locating the region/area of an instance of action/activity within a video

How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database
