Abstract

The invention discloses a fish behavior image recognition method based on improved AlexNet, and the method comprises the following steps: S1, building an item-based flexible attention algorithm which is used for the convolution function of a trunk part of the algorithm and the building of a multi-layer sensor, a decoder and a sampling layer of a branch part of the algorithm; s2, constructing a fish behavior image recognition sample library, and placing an item-based flexible attention module between a full connection layer and an output layer by using an improved AlexNet model; and S3, transplanting the trained fish image recognition knowledge graph into the optimized AlexNet model by adopting a model migration method to obtain a fish behavior recognition result. The method has the advantages that a traditional fish behavior image recognition algorithm is improved, under the same recognition speed, the recognition precision is higher, the convergence speed is higher, meanwhile, over-convergence is avoided, and the method has actual engineering application value.

Description

technical field [0001] The invention relates to the field of marine biological behavior image recognition processing, in particular to a fish behavior image recognition method based on improved AlexNet. Background technique [0002] How to realize smart fish farming and promote the transformation of my country's traditional marine fishery model is an urgent problem to be solved in China. The internal and external environment of fishery development is undergoing profound changes: the dual constraints of resources and the environment are tightening, fishery resources are increasingly depleted, waters are seriously polluted, and endangered species increase; fishery development methods are extensive, facilities and equipment are backward, production costs are rising, and benefits continue to decline; aquatic biological diseases are increasing, and there are hidden dangers in quality and safety. Some long-term production and ecological contradictions have not been effectively reso...
