FastTrackOrg9. trackR - Multi-object tracking with R
trackR is an object tracker for R based on OpenCV. It provides an easy-to-use (or so we think) graphical interface allowing users to perform multi-object video tracking in a range of conditions while maintaining individual identities.
trackR uses RGB-channel-specific background subtraction to segment objects in a video. A background image can be provided by the user or can be computed by trackR automatically in most situations. Overlapping objects are then separated using cross-entropy clustering, an automated classification method that provides good computing performance while being able to handle various types of object shapes. Most of the tracking parameters can be automatically estimated by trackR or can be set manually by the user.
trackR also allows users to exclude parts of the image by using masks that can be easily created and customized directly within the app.
