Abstract: In this paper, we propose a Mesh-hole grouping algorithm that detects damaged areas by comparing the area between neighboring net holes in order to detect damaged parts of net …

There are few works that use traditional computer vision methods like the Otsu threshold, the Hough transform, and convex hull algorithms that are used in to reconstruct and detect holes …

Aug 1, 2020 · There is no need to attach any load on the netting to obtain the netting state video without affecting the normal operation of fish and cage system, and the damage to the netting …

Fish can be cultured in one of four culture systems—ponds, raceways, recirculating systems or cages. A cage or net pen is a system that confines the fish or shellfish in a mesh enclosure. By …

Jul 21, 2022 · The actual images were collected from a net enclosure facility on Taohua Island and a net cage on Changqi Island in Zhoushan from July to September 2021, covering a …

May 1, 2019 · Typhoons and storm surges can destroy key elements of the fish cage, including failure of mooring lines, breakage of floating collar, and fish death caused by a significant …
