摘要

Objects detected in data may be filtered from an object recognition index. Data for object detection may be received. An object detection technique may be applied to the data to detect an object. If the object does not satisfy indexing criteria for the object recognition index, then the detected object may be excluded from the object recognition index.

說明書

Control plane 212 may also implement index filtering management 360 which may update or create new 362 indexing criteria. In some embodiments, the updates may be triggered by an update to an existing object detection pipeline 310 or addition of a new object detection pipeline 352. Changes or new indexing criteria may be determined based on analysis of false and true positives detected by the updated or additional object detection pipeline, as discussed in detail below with regard to FIG. 7. For example, if a new object detection pipeline 310 is added then index filtering 310 may be updated to include a filter 320 specific to the object detection pipeline 310, or threshold values for an existing filter may be modified, in some embodiments. Indexing filtering criteria may be stored in a data store (not illustrated) so that when a detect object is received from an object detection pipeline, the index filtering criteria for that pipeline may be retrieved an applied. Updates, therefore, may be made to the criteria in the data store, in some embodiments.
