摘要

Image retrieval has transitioned from retrieving images with single object descriptions to retrieving images by using complex natural language to describe desired image content. We present work on holistic image search to perform exact and approximate image retrieval that returns images from a database that most closely match the user's description. Our approach can handle simple queries for single objects (ex: cake) to more complex descriptions of multiple objects and prepositional relations between objects (ex: girl eating cake with a fork on a plate) in graph notation. In addition, our approach can generalize to retrieve queries that are semantically similar in case specific results are not found. We use the scene graph, developed in the Visual Genome dataset as a formalization of image content stored as a graph with nodes for objects and edges for relations describing objects in an image. We combine this with approximate search techniques for large-scale graphs and a semantic scoring algorithm developed by us to holistically retrieve images based on given search criteria. We also present a method to store scene graphs and metadata in graph databases using Neo4 J.
