| 45 | +abstract: >+ |
| 46 | + Litter is a known cause of degradation in marine environments and most of |
| 47 | + it travels in rivers before reaching the oceans. In this paper, we present |
| 48 | + a novel algorithm to assist waste monitoring along watercourses. While |
| 49 | + several attempts have been made to quantify litter using neural object |
| 50 | + detection in photographs of floating items, we tackle the more challenging |
| 51 | + task of counting directly in videos using boat-embedded cameras. We rely |
| 52 | + on multi-object tracking (MOT) but focus on the key pitfalls of false and |
| 53 | + redundant counts which arise in typical scenarios of poor detection |
| 54 | + performance. Our system only requires supervision at the image level and |
| 55 | + performs Bayesian filtering via a state space model based on optical flow. |
| 56 | + We present a new open image dataset gathered through a crowdsourced |
| 57 | + campaign and used to train a center-based anchor-free object detector. |
| 58 | + Realistic video footage assembled by water monitoring experts is annotated |
| 59 | + and provided for evaluation. Improvements in count quality are |
| 60 | + demonstrated against systems built from state-of-the-art multi-object |
| 61 | + trackers sharing the same detection capabilities. A precise error |
| 62 | + decomposition allows clear analysis and highlights the remaining |
| 63 | + challenges. |
