Images of Balls Transported on a Chute - Recording 2

This data set comprises images of balls on a chute. The images were recorded on the small-scale optical belt sorter Tablesort. A thorough description of the Tablesort system can be found in

This dataset is part of a batch of recordings on optical sorters. Please use the search function with the keyword "Tobias Hornberger" (in quotes) to find them.

The camera was recorded on a Bonito CL-400C. Please see the debayer script on GitHub. The frame rate is 192.9 Hz.

Algorithms for two key challenges can be developed and evaluated on the data sets:

1. Multitarget tracking for predicting the particle’s motion. This can be used to enhance the separation of optical sorters. For further details on this, see the publications

2. Classification of particles. The classification may use a multitarget tracker to accumulate visual features over time. One can also use the information on the trajectory to classify the particles. For information on this, refer to
