Abstract

The invention discloses a fish fine-grained image recognition method based on deep learning. The method comprises the following specific processing steps: 1) an image preprocessing step; 2) an image detection step; and 3) an image recognition step. According to the fish fine-grained image recognition method based on deep learning, rapid and effective recognition of different marine fishes in a complex marine environment is achieved, and the problems that features are not obvious and the like are solved.

Description

technical field [0001] The present invention relates to the technical field of detecting the distribution of underwater fish, and more specifically, it relates to a fish fine-grained image recognition method based on deep learning. Background technique [0002] As the most important type of marine biological resources, marine fish is not only an important source of food for human beings, but also an important force for maintaining the ecological balance of the earth. In the process of exploring marine fish resources, it is necessary to identify various species of fish, but the fish are of different shapes and sizes, making identification more complicated, and different species of the same type of fish usually have similar shapes , size, texture and other characteristics, it is very likely that misjudgment will occur and cause serious economic losses. Therefore, the research on the recognition technology of marine fish images has important academic value and economic value f...
