Transformer-Based Backbones for Scene Graph Generation A Comparative Analysis

Abstract

The Scene Graph is a modern structured representation of an image scene that explicitly describes the scene as a set of objects, attributes, and links between the objects (relationships). With the great advancements in the computer vision field, researchers dedicated their efforts towards more complex reasoning and a high level of understanding of visual scenes. Tasks like Visual Question Answering, image generation, and cross-modal retrieval are examples of Complex vision tasks that require a high level of visual scene understanding. Scene Graph is an effective data structure that highlights complex visual relationships presented in a scene. In this work, we provide a comparative analysis of Scene Graph Generation (SGG) backbone models. The contributed work aims to compare the Convolution Neural Networks (CNN) backbones and the vision transformer-based backbones using the RelTR model. The conducted analysis proved that both SwiftFormer L3 and MiT-B2 transformer backbones increased the model performance over the ResNet50 CNN backbone by 2.1 % and 2.5% Recall@50 respectively when experimented on the same Visual Genome 50 test split. The Visual Genome 50 is a tailored version of The Visual Genome dataset. It contains only the 50 most common relationships and the most frequent 150 object classes.
