• Abstract: Radiance Fields (RF) are popular to represent casually-captured scenes for new view synthesis and several applications beyond it. Mixed reality on personal spaces needs understanding and manipulating scenes represented as RFs, with semantic segmentation of objects as an important step. Prior segmentation efforts show promise but don't scale to complex objects with diverse appearance. We present the ISRF method to interactively segment objects with fine structure and appearance. Nearest neighbor feature matching using distilled semantic features identifies high-confidence seed regions. Bilateral search in a joint spatio-semantic space grows the region to recover accurate segmentation. We show state-of-the-art results of segmenting objects from RFs and compositing them to another scene, changing appearance, etc., and an interactive segmentation tool that others can use.

• Revisit Anything: Visual Place Recognition via Image Segment Retrieval [8.544326445217369]
  Existing visual place recognition pipelines encode the "whole" image and search for matches. We address this by encoding and searching for "image segments" instead of the whole images. We show that retrieving these partial representations leads to significantly higher recognition recall than the typical whole image based retrieval.

  We learn a novel feature field within a Neural Radiance Field (NeRF) representing a 3D scene. Our method takes view-inconsistent multi-granularity 2D segmentations as input and produces a hierarchy of 3D-consistent segmentations as output. We evaluate our method and several baselines on synthetic datasets with multi-view images and multi-granular segmentation, showcasing improved accuracy and viewpoint-consistency.

  Generalized Perception NeRF (GP-NeRF) is a novel pipeline that makes the widely used segmentation model and NeRF work compatibly under a unified framework. We propose two self-distillation mechanisms, i.e., the Semantic Distill Loss and the Depth-Guided Semantic Distill Loss, to enhance the discrimination and quality of the semantic field.

  We propose to imitate the backbone feature of off-the-shelf perception models to achieve zero-shot semantic segmentation with NeRF. Our framework reformulates the segmentation process by directly rendering semantic features and only applying the decoder from perception models. Furthermore, we can project the learned semantics onto extracted mesh surfaces for real-time interaction.

  We propose a component that learns to project image features into latent representations and reason between them. Our design encourages the latent regions to represent semantic concepts by ensuring that the activated regions are spatially disjoint. Our latent tokens are semantically interpretable and diverse and provide a rich set of features that can be transferred to downstream tasks.

The core of our method is a novel propagation strategy for individual objects' radiance fields with a bidirectional photometric loss. To the best of our knowledge, RFP is the first unsupervised approach for tackling 3D scene object segmentation for neural radiance field (NeRF)

Our framework, called NeRF with Self-supervised Object NeRF-SOS, encourages NeRF models to distill compact geometry-aware segmentation clusters. It consistently surpasses other 2D-based self-supervised baselines and predicts finer semantics masks than existing supervised counterparts.

  Referring image segmentation aims to segment the objects referred by a natural language expression. Previous methods usually focus on designing an implicit and recurrent interaction mechanism to fuse the visual-linguistic features to directly generate the final segmentation mask. We present a "Then-Then-Segment" scheme to tackle these problems. Our framework is simple but surprisingly effective.

• Improving Semantic Segmentation via Decoupled Body and Edge Supervision [89.57847958016981]
  Existing semantic segmentation approaches either aim to improve the object's inner consistency by modeling the global context, or refine objects detail along their boundaries by multi-scale feature fusion. In this paper, a new paradigm for semantic segmentation is proposed. Our insight is that appealing performance of semantic segmentation requires textitexplicitly modeling the object textitbody and textitedge, which correspond to the high and low frequency of the image. We show that the proposed framework with various baselines or backbone networks leads to better object inner consistency and object boundaries.
