I think it is related to converting an image into text according to some ontological or semantic models; then we may speak about visual retrieval depending on "contextual information" technique.

Relevant contexts for this are eg sea, boat, cloud, sky etc. (image contextual). Whether you wear a jacket or hat or shoes etc is a context image.
