Jianhui Chen, Keyu Lu, Sijia Tian, James J. Little

TL;DR
This paper introduces a novel approach for soccer camera selection using internet videos, employing a random survival forest for data imputation and a spatial-appearance heatmap, supported by a large new dataset, achieving superior performance.
Contribution
The paper presents a new method combining RSF and spatial-appearance heatmaps for camera selection, along with the largest dataset for soccer broadcast camera prediction.
Findings
Outperforms state-of-the-art methods on the new dataset
Utilizes auxiliary games to enhance camera selection accuracy
Effective data imputation with RSF improves model performance
Abstract
This work addresses camera selection, the task of predicting which camera should be "on air" from multiple candidate cameras for soccer broadcast. The task is challenging because of the scarcity of learning data with all candidate views. Meanwhile, broadcast videos are freely available on the Internet (e.g. Youtube). However, these videos only record the selected camera views, omitting the other candidate views. To overcome this problem, we first introduce a random survival forest (RSF) method to impute the incomplete data effectively. Then, we propose a spatial-appearance heatmap to describe foreground objects (e.g. players and balls) in an image. To evaluate the performance of our system, we collect the largest-ever dataset for soccer broadcasting camera selection. It has one main game which has all candidate views and twelve auxiliary games which only have the broadcast view. Our…
