Few-shot object detection aims to simultaneously localize and classify the objects in an image with limited training samples.
However, most existing few-shot object detection methods focus on extracting the features of a few samples of novel classes that lack diversity.
... propose a novel approach in which ... train a generator to generate synthetic data for novel classes
... goal is to train a generator that captures the data variations of the base dataset ... then transform the captured variations into novel classes by generating synthetic data with the trained generator.
To encourage the generator to capture data variations on base classes, ... train the generator with an optimal transport loss that minimizes the optimal transport distance between the distributions of real and synthetic data.
Extensive experiments on two benchmark datasets demonstrate that the proposed method outperforms the state of the art ...
