Object detection is a fundamental task in computer vision, with its applications ranging from autonomous driving to scene recognition.

The suggested approach utilizes a transformer-based model for object detection, followed by a threshold to assign tags to POI scenes. These tags are then used to train a novel multimodal model, called WORLD (Weight Optimization for Representation and Labeling Descriptions), which is capable of classifying and contextually tagging POI scenes based on their visual features.

摘要

Object detection is a fundamental task in computer vision, with its applications ranging from autonomous driving to scene recognition. In the domain of Points-of-Interest (POI), object recognition can aid in the analysis of complex urban environments that contain various types of infrastructure, people, and activities. This paper addresses this challenge by proposing a Bag-of-Objects (BoO) methodology for POI scene contextual tagging. The suggested approach utilizes a transformer-based model for object detection, followed by a threshold to assign tags to POI scenes. These tags are then used to train a novel multimodal model, called WORLD (Weight Optimization for Representation and Labeling Descriptions), which is capable of classifying and contextually tagging POI scenes based on their visual features.
