報告摘要：

Aquaculture is a vital sector in global food production, with shrimp farming being a key branch within it. Accurate individual counting of shrimp fry is crucial for effective aquaculture management. However, traditional manual counting methods are time-consuming, labor-intensive, and prone to errors. Additionally, challenges such as mutual occlusion and varying lighting conditions in densely populated areas of shrimp fry can lead to inaccurate counting. In this paper, we propose the use of a high-resolution network, HRNET, to extract important information from images at multiple scales, mitigating information loss caused by external factors like lighting and overlapping due to mutual occlusion. By incorporating attention mechanisms, we enhance the feature representation of the backbone network for small targets, thereby improving recognition and counting accuracy. Furthermore, to address differences between dense and sparse regions, we employ dilated convolutions to expand the receptive field and replace the mean squared error (MSE) loss, which solely focuses on pixel-level average errors, with the DMS-SSIM loss function that considers similarity in subtle image structures and quality. Experimental results demonstrate a significant improvement in both mean absolute error (MAE) and MSE.
