• Abstract: The goal of this paper is to be able to retrieve images using a compound query that combines object instance information from an image, with a natural text description of what that object is doing or where it is. For example, to retrieve an image of "Fluffy the unicorn (specified by an image) on someone's head". To achieve this we design a mapping network that can "translate" from a local image embedding (of the object instance) to a text token, such that the combination of the token and a natural language query is suitable for CLIP style text encoding, and image retrieval. Generating a text token in this manner involves a simple training procedure, that only needs to be performed once for each object instance. We show that our approach of using a trainable mapping network, termed pi-map, together with frozen CLIP text and image encoders, improves the state of the art on two benchmarks designed to assess personalized retrieval.

  We study the zero-shot Composed Image Retrieval (ZS-CIR) task, which is to retrieve the target image given a reference image and a description without training on the triplet datasets. Previous works generate pseudo-word tokens by projecting the reference image features to the text embedding space. We propose a Knowledge-Enhanced Dual-stream zero-shot composed image retrieval framework (KEDs) KEDs implicitly models the attributes of the reference images by incorporating a database.

  Text-based person search (TBPS) aims to retrieve the images of the target person from a large image gallery based on a given natural language description. Existing methods are dominated by training models with parallel image-text pairs, which are very costly to collect. In this paper, we make the first attempt to explore TBPS without parallel image-text data.

  Composed image retrieval searches for a target image based on a multi-modal user query comprised of a reference image and modification text. We propose a bi-directional training scheme that leverages such reversed queries and can be applied to existing composed image retrieval architectures. Experiments on two standard datasets show that our novel approach achieves improved performance over a baseline BLIP-based model.

  Proposal-text alignment is performed using contrastive learning, producing a score for each proposal that reflects its semantic alignment with the text query. The Region Proposal Network (RPN) is used to generate object proposals, and the end-to-end training process allows for an efficient and effective solution for semantic image search.

Our method significantly outperforms optimization-based text-to-image methods in terms of image quality.

  Fine-grained image retrieval often requires the ability to also express the where in the image the content they are looking for is. In this paper, we describe an image retrieval setup where the user simultaneously describes an image using both spoken natural language (the "what") and mouse traces over an empty canvas (the "where") Our model is capable of taking this spatial guidance into account, and provides more accurate retrieval results compared to text-only equivalent systems.
