SIMPL: Generating Synthetic Overhead Imagery to Address Zero-shot and Few-Shot Detection Problems
[article]
2021
arXiv
pre-print
Preserved Fulltext
We demonstrate the effectiveness of using SIMPL synthetic imagery for training DNNs in zero-shot scenarios where no real imagery is available; and few-shot learning scenarios, where limited real-world ...
In this work we present a simple approach - termed Synthetic object IMPLantation (SIMPL) - to easily and rapidly generate large quantities of synthetic overhead training data for custom target objects. ...
CONCLUSIONS In this work we investigated the use of synthetic overhead imagery as a general approach to address zeroshot and few-shot object detection problems. ...

To treat this problem, we survey and develop novel synthetic data generation and augmentation techniques for enhancing low/zero-sample learning in satellite imagery. ...
In addition to extending synthetic data generation approaches, we propose a hierarchical detection approach to improve the utility of synthetic training samples. ...
Low-shot and zero-shot learning The problems of low-shot learning (few training examples of target class) and zero-shot learning (no training examples of target class) have spawned a very active body of ...

What makes this approach interesting is the ability of the competition between neurons to automatically filter noise, yet with the capability of generalizing the desired shape and scale. ...
The neural approach consists of a mosaic of topographic maps that are each trained using competitive Hebbian learning to rapidly detect image features of a pre-defined shape and scale. ...
A simple one-shot training scheme can be used to overcome this and hence allow us to scale up the maps to avoid having map boundaries. ...
