Awesome-Scene-Graph-Generation

🎨 Introduction

A scene graph is a topological structure representing a scene described in text, image, video, or etc. In this graph, the nodes correspond to object bounding boxes with their category labels and attributes, while the edges represent the pair-wise relationships between objects.

🍕 Scene Graph Generation

2D (Image) Scene Graph Generation

There are three subtasks:

  • Predicate classification: given ground-truth labels and bounding boxes of object pairs, predict the predicate label.
  • Scene graph classification: joint classification of predicate labels and the objects' category given the grounding bounding boxes.
  • Scene graph detection: detect the objects and their categories, and predict the predicate between object pairs.

LLM-based

Non-LLM-based

Panoptic Scene Graph Generation

Compared with traditional scene graph, each object is grounded by a panoptic segmentation mask in PSG, achieving a compresensive structured scene representation.

Spatio-Temporal (Video) Scene Graph Generation

Spatio-Temporal (Video) Scene Graph Generation, a.k.a, dynamic scene graph generation, aims to provide a detailed and structured interpretation of the whole scene by parsing an event into a sequence of interactions between different visual entities. It ususally involves two subtasks:

  • Scene graph detection: aims to generate scene graphs for given videos, comprising detection results of subject-object pari and the associatde predicates. The localization of object prediction is considered accurate when the Intersection over Union (IoU) between the prediction and ground truth is greater than 0.5.
  • Predicate classification: classifiy predicates for given oracle detection results of subject-object pairs.
  • NotedNoted: Evaluation is conducted with two settings: ***With Constraint*** and ***No constraints***. In the former the generated graphs are restricted to at most one edge, i.e., each subject-object pair is allowed only one predicate and in the latter, the graphs can have multiple edges. More details can refer to Metrics.

Audio Scene Graph Generation

3D Scene Graph Generation

Given a 3D point cloud $P \in R^{N×3}$ consisting of $N$ points, we assume there is a set of class-agnostic instance masks $M = {M_1, ..., M_K}$ corresponding to $K$ entities in $P$, 3D Scene Graph Generation aims to map the input 3D point cloud to a reliable semantically structured scene graph $G = {O, R}$. Compared with 2D scene graph Generation, the input of 3D SGG is point cloud.

Referring Expression Comprehension

  • Zero-shot Referring Expression Comprehension via Structural Similarity Between Images and Captions Paper Star
    A triplet-matching objective to fine-tune the vision-language alignment models.To mitigate this gap, we leverage large foundation models to disentangle both images and texts into triplets in the format of (subject, predicate, object). After that, grounding is accomplished by calculating the structural similarity matrix between visual and textual triplets with a VLA model, and subsequently propagate it to an instancelevel similarity matrix. Furthermore, to equip VLA models with the ability of relationship nderstanding, we design a triplet-matching objective to fine-tune the VLA models on a collection of curated dataset containing abundant entity relationships
