Labeling Projects

This document is intended to be a living document about the processes for labeling for the FishSense project.

Getting Started

Please log in to Labeler. If you do not yet have an account, please contact your team lead or a Label Studio admin to access the system.

After logging in, you will have a page listing all available labeling projects. Please only label for projects that you have been asked to label. Each project may have specific instructions for what they need to be labeled. The instructions for FishSense are described in the sections below. This section will discuss general Label Studio usage.

After opening a project, please click the blue "Label All Tasks" button. This will provide you with the best labeling experience.

To label, follow these steps:

1. If there is nothing to label, simply click submit. Otherwise, follow the remaining steps.
2. Zoom into the image as necessary. Use the zoom/pan controls to the right of the image.
3. Select the appropriate label for your image.
4. Select the point or points you wish to label. Your labels appear on the screen and in the bottom right of your display.
5. When finished, click submit.

Lasers

Navigate to the FishSense Laser in Label Studio.

You will be presented with images containing zero, one, or two lasers. The majority of these images will contain only a single laser. These lasers may be red or green. So that this data can be used for both processing and data analysis, please select the proper label for the laser you are labeling. For example, if you are labeling a red laser, please select "Red Laser" as your label. It is necessary to get the dot as close to the center of the laser as possible. Error in distance measurements are introduced if not properly centered.
