📝 摘要(中文)
交互式图像分割的目标是通过视觉或语言提示来划定图像中的特定区域。然而,现有的专业模型和通用模型在低延迟和高质量的交互分割以及多样化提示方面仍面临挑战。专业模型由于提示有限和任务特定设计,更新提示时需要重新计算图像,导致高延迟。尽管通用模型如Segment Anything Model(SAM)在提示多样性和效率上表现出色,但在高质量分割上仍落后于最先进的专业模型。本文深入探讨了两种模型之间的架构差异,并提出了一种新的交互分割方法SegNext,旨在实现低延迟、高质量和多样化提示支持,实验结果表明该方法在HQSeg-44K和DAVIS数据集上均优于现有最先进的方法。

📄 摘要(原文)
The goal of interactive image segmentation is to delineate specific regions within an image via visual or language prompts. Low-latency and high-quality interactive segmentation with diverse prompts remain challenging for existing specialist and generalist models. Specialist models, with their limited prompts and task-specific designs, experience high latency because the image must be recomputed every time the prompt is updated, due to the joint encoding of image and visual prompts. Generalist models, exemplified by the Segment Anything Model (SAM), have recently excelled in prompt diversity and efficiency, lifting image segmentation to the foundation model era. However, for high-quality segmentations, SAM still lags behind state-of-the-art specialist models despite SAM being trained with x100 more segmentation masks. In this work, we delve deep into the architectural differences between the two types of models. We observe that dense representation and fusion of visual prompts are the key design choices contributing to the high segmentation quality of specialist models. In light of this, we reintroduce this dense design into the generalist models, to facilitate the development of generalist models with high segmentation quality. To densely represent diverse visual prompts, we propose to use a dense map to capture five types: clicks, boxes, polygons, scribbles, and masks. Thus, we propose SegNext, a next-generation interactive segmentation approach offering low latency, high quality, and diverse prompt support. Our method outperforms current state-of-the-art methods on HQSeg-44K and DAVIS, both quantitatively and qualitatively.
