Abstract
The image matching apparatus () comprises a ground-view feature extractor (), an aerial-view feature extractor (), and a determination unit (). The ground-view feature extractor () extracts features from the ground-view image () to generate feature maps without attention mechanism and feature maps with attention mechanism. The aerial-view feature extractor () extracts features from the aerial-view image () to generate feature maps without attention mechanism and feature maps with attention mechanism. The determination unit () computes a similarity score, which indicates a degree of similarity between the ground-view image () and the aerial-view image (), based on the generated feature maps. Then, the determination unit () determines whether the ground-view image () matches the aerial-view image () based on the similarity score.
