Welcome to the ROI Coder user guide. The ROI Coder is a user interface for annotating dynamic regions of interest (ROIs) on video frames for eye tracking or computer vision analysis. Included tool ('extract_frames.m') creates directory of video frames from Quicktime-compatiable video files for coding.

Feature list:

• Extract/read directories of sequential .jpg files
• Play/rewind/step through video frames
• Click/drag to create rectangular ROIs on frames
• Flexible keyboard controls for fine-tuning ROIs
• Save/load multiple .csv files for different ROI coding sets
• Autosave coding
• Visualization of coded/uncoded regions

This wiki documents the main steps for preparing, coding, and analyzing ROI data:

• Preparing your files
• Loading and saving data
• Navigation and coding
• ROI coding output

I hope this software will be useful to other researchers. If there are changes to be made to make this useful or bugs that you notice, please log an issue directly on Github.
