Object members
| Measurement name | Description | Element type | Indexing |
|---|---|---|---|
| barycenterX | The X position of the center of mass in pixel coordinates, also known as the X moment of order 1. | Floating point | [time] |
| barycenterY | The Y position of the center of mass in pixel coordinates, also known as the Y moment of order 1. | Floating point | [time] |
| momentXX | The XX moment of order 2 in pixel coordinates. It is the first diagonal element of the 2D covariance matrix. | Floating point | [time] |
| momentYY | The YY moment of order 2 in pixel coordinates. It is the second diagonal element of the 2D covariance matrix. | Floating point | [time] |
| momentXY | The XY moment of order 2 in pixel coordinates. It is the corner elements of the 2D covariance matrix. | Floating point | [time] |
| orientation | The main orientation, in degrees, of the image structures. It is given by the orientation of the eigenvector associated with the largest eigenvalue of the covariance matrix. | Floating point | [time] |
