1 More examples from the object-pair database
In this section, we show more examples in the object-pair database which are used for the classi-
fication experiment (section 7.1 in the paper).

2 Hierarchy structure for different scenes
In this section, we show structures of 9 example scenes. As the number of objects in some scenes is
quite large, it is difficult to visualize the structure by a graph. Here we indicate the object groups
in each level of the scene structure using different colours.

3 Retrieval results for the four queries (which are evalu-
ated in section 7.3)
In this section, we show the retrieval results for the four queries which are evaluated by user’s
labels in section 7.3. Note that here the retrieval was done on the whole database.
The four queries are:
Object 8 of scene00050 (the plate)
Object 37 of scene00087 (the water dispenser)
Object 14 of scene00118 (the chair)
Object 14 of scene00109 (the table)
We show retrieval results for all depths (from 1 to the maximal depth) for each query. We also
show both the results of our method(IBS) and the displacement feature(DIS) for comparison.
In the rest of this document, we show more retrieval results. The query object is always shown
in a red bounding box in the query scene. The result objects are shown in red, and the result
scenes are ordered by their similarity(left-to-right, top-to-bottom). The note below each result
with the format “XXXX-YY” means the current result is the YY-th object of the scene named
XXXX. The object ID and the scene names are from the Stanford Scene Database.
