Claim 17:
18. One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors implement a contextualized visual search (CVS) system and cause the CVS system to:
receive a query image and a search request to search for items that display a pictogram that includes the query image;
convert, using a first machine learning model, the query image into a query feature vector;
analyze, using a second machine learning model, target feature vectors of target images of a plurality of items, wherein the second machine learning model is trained to examine different sub-regions of a given target image to (a) determine whether individual ones of the sub-regions contain a view of the query image and (b) identify one or more locations of one or more views of the query image in the given target image;
identify, based at least in part on the analysis, a set of matching images from the target images that contain views of the query image and a set of matching items associated with the matching images; and
output search results that indicate the matching items, the matching images, and locations of the views of the query image in the matching images.
