Scene Graph Generation with External Knowledge and Image Reconstruction
Scene graph generation has received growing attention with the advancements
in image understanding tasks such as object detection, attributes and
relationship prediction,~\etc. However, existing datasets are biased in terms
of object and relationship labels, or often come with noisy and missing
annotations, which makes the development of a reliable scene graph prediction
model very challenging. In this paper, we propose a novel scene graph
generation algorithm with external knowledge and image reconstruction loss to
overcome these dataset issues. In particular, we extract commonsense knowledge
from the external knowledge base to refine object and phrase features for
improving generalizability in scene graph generation. To address the bias of
noisy object annotations, we introduce an auxiliary image reconstruction path
to regularize the scene graph generation network. Extensive experiments show
that our framework can generate better scene graphs, achieving the
state-of-the-art performance on two benchmark datasets: Visual Relationship
Detection and Visual Genome datasets.Comment: 10 pages, 5 figures, Accepted in CVPR 201
Target-Tailored Source-Transformation for Scene Graph Generation
Scene graph generation aims to provide a semantic and structural description
of an image, denoting the objects (with nodes) and their relationships (with
edges). The best performing works to date are based on exploiting the context
surrounding objects or relations,e.g., by passing information among objects. In
these approaches, to transform the representation of source objects is a
critical process for extracting information for the use by target objects. In
this work, we argue that a source object should give what tar-get object needs
and give different objects different information rather than contributing
common information to all targets. To achieve this goal, we propose a
Target-TailoredSource-Transformation (TTST) method to efficiently propagate
information among object proposals and relations. Particularly, for a source
object proposal which will contribute information to other target objects, we
transform the source object feature to the target object feature domain by
simultaneously taking both the source and target into account. We further
explore more powerful representations by integrating language prior with the
visual context in the transformation for the scene graph generation. By doing
so the target object is able to extract target-specific information from the
source object and source relation accordingly to refine its representation. Our
framework is validated on the Visual Genome bench-mark and demonstrated its
state-of-the-art performance for the scene graph generation. The experimental
results show that the performance of object detection and visual relation-ship
detection are promoted mutually by our method
