This paper proposes a new retrieval problem and conducts

the initial study. This problem aims at finding the location of an item

in a supermarket by means of visual retrieval. It is modelled as objectbased

retrieval and approached using the local invariant features. Two

existing retrieval methods are investigated and their similarity measures

are modified to better fit this new problem. More importantly, through

the study this new retrieval problem proves itself to be a challenging

task. An instant application of it is to help the customer find what they

want without physically wandering around the shelves but a wide range

of potential applications could be expected.
