Fish identification and vaccine injection method based on fractal theory and BP (Back Propagation) algorithm

Abstract

The invention provides a fish identification and vaccine injection method based on a fractal theory and a BP (Back Propagation) algorithm. The method comprises the steps of acquiring a color image offish; performing preprocessing and image segmentation on the color image to obtain a target image; extracting a characteristic value of each segmented target image by use of a fractal theory algorithmto obtain a comprehensive characteristic vector group; training the comprehensive characteristic vector group by use of a BP neural network algorithm, and identifying an image which meet the combination requirement of a specific part of the fish in the target image; and performing vaccine injection on the fish meeting the requirement. According to the fish identification and vaccine injection method based on the fractal theory and the BP algorithm, a novel method is provided for representation of the body part of the fish by use of the fractal theory algorithm, eight characteristic values forrepresenting the fish can reflect the information of the body part of the fish and facilitate distinguishing. Through the combination of the fractal theory and the BP algorithm, the image of the combination of a fish head and a back spine is effectively identified, a good identification method is provided for fish vaccine injection, mechanical identification is achieved, automatic injection is adopted in an injection process, and thus the manpower burden is alleviated.

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.
