- Abstract summary: We propose an efficient approach to analyze the spatial distribution status and motion patterns of juvenile clownfish maintained in aquaria.
The estimated displacement is the key factor in assessing the dispersion and velocity.
We test the system design on a database containing two days of video streams of juvenile clownfish maintained in aquaria.

- Abstract: Monitoring and detecting fish behaviors provide essential information on fish
welfare and contribute to achieving intelligent production in global
aquaculture. This work proposes an efficient approach to analyze the spatial
distribution status and motion patterns of juvenile clownfish (Amphiprion
bicinctus) maintained in aquaria at three stocking densities (1, 5, and 10
individuals/aquarium). The estimated displacement is the key factor in
assessing the dispersion and velocity to express the clownfish's spatial
distribution and movement behavior in a recirculating aquaculture system.
Indeed, we aim at computing the velocity, magnitude, and turning angle using an
optical flow method to assist aquaculturists in efficiently monitoring and
identifying fish behavior. We test the system design on a database containing
two days of video streams of juvenile clownfish maintained in aquaria. The
proposed displacement estimation reveals good performance in measuring
clownfish's motion and dispersion characteristics. Furthermore, we demonstrate
the effectiveness of the proposed technique for quantifying variation in
clownfish activity levels between recordings taken in the morning and
afternoon.

Motion Refinement [65.08165593201437]
We explore egocentric whole-body motion capture using a single fisheye camera, which simultaneously estimates human body and hand motion.
This task presents significant challenges due to the lack of high-quality datasets, fisheye camera distortion, and human body self-occlusion.
We propose a novel approach that leverages FisheyeViT to extract fisheye image features, which are converted into pixel-aligned 3D heatmap representations for 3D human body pose prediction.

Opportunities and challenges [0.5156484100374059]
Monitoring the water quality and controlling feeding are fundamental elements of balancing fish productivity and shaping the fish growth process.
Currently, most fish-feeding processes are conducted manually in different phases and rely on time-consuming and challenging artificial discrimination.
This paper reviews the main control design techniques for fish growth in aquaculture systems, namely algorithms that optimize the feeding and water quality of a dynamic fish growth process.
