Title: Vision-Language Mapping for Referring Image Segmentation

Abstract: Image segmentation is a classic topic in computer vision. In recent years, referring image segmentation has attracted increasing research interest. Beyond traditional image segmentation, referring image segmentation expects to segment out an object described by a language query from an image. As it needs to correlate vision and language, referring image segmentation is a more challenging task. This talk focuses on building more accurate vision-language mappings for the referring image segmentation task. I will first present a key word extraction model. It extracts key words from the language query to suppress the noise in the query and to highlight the desired object. Next, I will present a key-word-aware visual context model. This model is designed to learn the relationships of multiple visual objects based on the language query, which is crucial to localize and segment objects in accordance with the query. Finally, I will present a query reconstruction network that builds a bidirectional vision-language mapping to confirm the vision-language consistency. Furthermore, for inconsistent segmentations and queries, an iterative segmentation correction method is proposed to correct them.
