pysteps.tracking#
Implementations of feature tracking methods.
pysteps.tracking.interface#
Interface to the tracking module. It returns a callable function for tracking features.

Return a callable function for tracking features. |
pysteps.tracking.lucaskanade#
The Lucas-Kanade (LK) feature tracking module.
This module implements the interface to the local Lucas-Kanade routine available in OpenCV.
|
Interface to the OpenCV Lucas-Kanade feature tracking algorithm (cv.calcOpticalFlowPyrLK). |
pysteps.tracking.tdating#
Thunderstorm Detection and Tracking (DATing) module This module was implemented following the procedures used in the TRT Thunderstorms Radar Tracking algorithm ([HMG+04]) used operationally at MeteoSwiss. Full documentation is published in [FGGB21]. Modifications include advecting the identified thunderstorms with the optical flow obtained from pysteps, as well as additional options in the thresholding.

This function performs the thunderstorm detection and tracking DATing. |
|
This function performs the actual tracking procedure. |
|
This function advects all identified cells with the estimated flow. |
|
This function matches the advected cells of the previous timestep to the newly identified ones. |
|
The coupled cell tracks are re-arranged from the list of cells sorted by time, to a list of tracks sorted by ID. |
