Overview

Feature Points (also known as interest points or key points) enable key point detection for a group.
Architectures such as PoseNet and OpenPose support feature points as input. Common use cases include facial recognition and body pose detection.

Create a Feature Points Label

Plainsight does not support model training for this label type.
    1.
    Navigate to the "Label Definitions" sub-tab of your project
    2.
    Type label name in the Label Name field
    3.
    Choose Feature Points from the Label Type dropdown
    4.
    Select label color from the color chooser menu
    5.
    Select Start Color and End Color from the chooser menu. The group of points will begin and end with a set of colors in that spectrum.

    Enter the number of points in the Count field
    7.
    Click "Save" button
    8.
    Repeat as needed for multiple labels

Data format

A Feature Point schema element creates an array of objects with data consisting of an array of nullable points. Each points is a XY coordinate relative (0.0 to 1.0) to width and height respectively.
