Multi‐label learning based target detecting from multi‐frame data
2021
IET Image Processing
Preserved Fulltext
Owing to the progress of multiple frames time series data, or video satellites, target detecting from space-borne satellite videos has been available. ...
This paper considers target detecting from time series data as multi-label problem as there are several different kinds of background objects and targets of interest. ...

We present a new, iterative learning algorithm to determine an optimal viewpoint invariant reference frame from training images in a data-driven manner. ...
We compare multi-view and viewpoint invariant representations trained and tested on the same data, where the viewpoint invariant approach results in fewer false positive detections and higher average precision ...
Ideally, fully unsupervised learning could derive an optimal invariant reference frame from data, however unsupervised learning is a challenging task even in the single viewpoint case. ...
