labelaction 1.1.0

A GUI tool for annotating action in video files.

Animal Behavior Annotation Tool(labelaction)

This is a GUI-based tool for annotating animal behavior in video files. Built using Python and PyQt5, this application allows users to load a video, navigate through frames, and label different behaviors for multiple subjects (referred to as "pigeons" in this tool).

Features

• Simultaneous annotation of behaviors and postures: Users can annotate both behaviors (e.g. feeding, drinking, etc.) and postures (e.g. standing, lying down, etc.) of pigeons during video playback, and each annotation can be done independently.

• Timeline visualization: The program provides a visual timeline for each pigeon to show the behavior and posture annotations for quick viewing and editing.

• Video frame navigation: the user can use buttons or shortcut keys (such as 'D' and 'S') to quickly advance or rewind video frames for easy and precise labeling.

• Color coding: Different behaviors and gestures are identified using different colors, making annotation more intuitive and allowing users to quickly identify information by color.

• Export function: Users can export annotation data to CSV file, supporting two formats: original annotation and sorted annotation data, which is convenient for subsequent data analysis and processing.

• Multi-pigeon support: the program allows independent annotation of multiple pigeons for complex experimental scenarios.

Prerequisites

• Python (>= 3.6)

• Libraries: The following libraries are required:

  • PyQt5

  • OpenCV

  • pandas
