Managing object tracking

A computing apparatus comprising:

• one or more computer processors;
• and
• one or more computer memories configured to cause the one or more computer processors to manage tracking of an object moving in a three-dimensional environment, by performing operations comprising:
• obtaining an indication of a region and a region tracking condition to be applied to the tracking of the object in the region, wherein the region pertains to a portion of a field of view of an electromagnetic sensor for tracking of the object in the three-dimensional environment,
• obtaining an observation relating to the tracking of the object, wherein the observation is generated based on at least one two-dimensional representation of the field of view, wherein said at least one two-dimensional representation has been captured by the electromagnetic sensor, and wherein the observation is includable in a set of observations defining a path of the object in the field of view,
• determining that the observation matches the region,
• in an evaluation action, evaluating whether the observation and/or the path fulfills the region tracking condition of the region or not, and
• wherein the operations comprise:
• retaining, based on the evaluation action, the observation and/or the path in continued tracking of the object, or
• discarding, based on the evaluation action, the observation and/or the path from continued tracking of the object,
• wherein the region tracking condition comprises one or more of:
• a second instruction that the path shall be discarded when the path, including the observation, fulfils a criterion relating to a speed and/or a jaggedness,
• a third instruction that the observation shall be discarded, and that the observation shall be replaced with an extrapolated observation derived from the path, in which the observation is not included,
• a fourth instruction that the observation shall be included in order to continue the tracking of the object, while not allowing use of an extrapolated observation derived from the path, in which the observation is not included, and/or
• a fifth instruction that the observation, comprising a blob, shall be discarded when a brightness of the blob is less than a brightness of a background at the blob.
