Non-Contact Phenotypic Measurement and Body Mass Prediction of Penaeus japonicus Based on Skeletonization and Multi-View Comparison.

Abstract excerpt

To address systematic errors in prawn total length measurement caused by natural curvature and challenges in body mass prediction under random postures in aquaculture, this study proposes an automated phenotypic measurement and body mass prediction framework integrating skeleton-based nonlinear length estimation and multi-view feature analysis. Instance segmentation (YOLO11n-seg) obtains prawn head and abdomen...
