A Fish Identification and Vaccine Injection Method Based on Fractal Theory and BP Algorithm

Abstract

The invention provides a method for fish identification and vaccine injection based on fractal theory and BP algorithm, comprising: obtaining a color image of fish; performing preprocessing on the color image, image segmentation to obtain a target image; The eigenvalue of the target image obtains the comprehensive feature vector group; the BP neural network algorithm is used to train the comprehensive feature vector group, and in the target image, the image that meets the combination requirements of the specific parts of the fish is identified; the fish that meet the requirements are vaccinated injection. The invention provides a brand-new method for characterization of fish body parts by adopting a fractal theory algorithm, and the eight eigenvalues ​​representing fish can better reflect the information of fish body parts and facilitate distinction. Combining fractal theory and BP algorithm to effectively identify the image required by the combination of fish head and back, it provides a good identification method for fish vaccine injection, realizes machine identification, and uses automatic injection in the injection process to reduce the labor burden.

Description

technical field [0001] The invention relates to the field of fish body part identification and vaccine injection, in particular to a fish identification and vaccine injection method based on fractal theory and BP algorithm. Background technique [0002] Fish vaccine injection is one of the most important tasks in fish fry breeding projects. The purpose of vaccination is to prevent fish diseases, ensure the healthy growth of fish and increase production. If you want to get healthy, large output, and good meat quality, you can breed The fish need to be vaccinated, otherwise the fish pond aquaculture industry will definitely suffer great economic losses. At present, there are three main methods of vaccination for aquatic products: injection, oral administration, and immersion. Among them, the injection vaccine has the characteristics of less dosage, high antibody titer, and long duration of immunity.
