A new model to retrieve images based on sketches

In recent years, researchers have been developing increasingly advanced computational techniques, such as deep learning algorithms, to complete a variety of tasks. One task that they have been trying to address is known as "sketch-based image retrieval" (SBIR). SBIR tasks entail retrieving images of a particular object or visual concept among a wide collection or database based on sketches made by human users. To automate this task, researchers have been trying to develop tools that can analyze human sketches and identify images that are related to the sketch or contain the same object. Despite the promising results achieved by some of these tools, developing techniques that perform consistently well on SBIR tasks has so far proved challenging.
