Image coordinate system¶
The same coordinate system as in OpenCv is used. So an image is treated as a matix. The x-axis increases to the right and the y-axis increases while moving downwards in the coordinate system, as in matrix notation.
All annotations are defined relative to the image.
Bounding Box definition¶
- x: Defines the x-coordinate of the center of a bounding box (relative, in pixels).
- y: Defines the y-coordinate of the center of a bounding box (relative, in pixels).
- width: Defines the width of a bbox (relative, in pixels).
- height: Defines the height of a bbox (relative, in pixels).
