BAE-Net: A Band Attention Aware Ensemble Network for Hyperspectral Object Tracking

Abstract

Hyperspectral videos contain images with a large number of light wavelength indexed bands that can facilitate material identification for object tracking. Most hyperspectral trackers use hand-crafted features rather than deep learning generated features for image representation due to limited training samples. To fill this gap, this paper introduces a band attention aware ensemble network (BAE-Net) for deep hyperspectral object tracking, which takes advantages of deep models trained on color videos for feature representation. Specifically, an autoencoder-like band attention block is introduced to learn the dependencies among bands and generate band-wise weights. Guided by these weights, hyperspectral images are then divided into a number of three-channel images. These three-channel images are fed into a deep color tracking network, producing several weak trackers. Finally, weak trackers are fused using ensemble learning for target location. Experimental results on hyperspectral datasets show the effectiveness and advantages of the proposed deep hyperspectral tracker.
