Images of a fixture may be acquired by cameras positioned with a field-of-view of the fixture. Such images are processed to identify estimated tops of items at the fixture. Using the estimated tops and item data for items designated for stowage at the fixture, one or more estimated locations of items (such as bounding boxes representative of the items) may be determined. Each estimated location for an item is tested for validity. For example, each estimated location is checked to see if the estimated location is within a working volume of the fixture. If the estimated location of the item is within the working volume, the item is determined to be valid. Otherwise, the item is deemed invalid.
