Method and system for processing image of diseased fish body

Abstract

The invention provides a method and a system for processing the image of a diseased fish body. The method for processing the image of a diseased fish body comprises the following steps: obtaining the image of the diseased fish body; obtaining the image of a fish body zone from the fish body image; obtaining an abnormal target zone image from the image of a fish body zone; and removing a non-specktarget zone image from the abnormal target zone image to obtain a speck target image. According to the method and the system for processing the image of a diseased fish body, the corresponding speck target image of the speck of the diseased fish can be quickly and accurately obtained to provide basis data for automatically recognizing fish diseases by a computer, so that a technician can conveniently know the specific situation of the diseases of the diseased fish to take measures in time so as to prevent the fulminating disease of aquaculture fish from being spread, thereby lowering loss brought by the fulminating disease of aquaculture fish. In addition, the method for processing the image of a diseased fish body is simple to operate and has good adaptability.

Description

technical field [0001] The invention relates to image processing technology, in particular to a fish body image processing method and system of diseased fish. Background technique [0002] At present, my country's fish farming industry is developing in the direction of intensive farming, and the scale of farming continues to expand. With the rapid development of the fish farming industry, the probability of aquaculture fish suffering from explosive diseases continues to increase. The explosive disease of aquaculture fish is an acute comprehensive fish disease, which has the characteristics of diverse disease types, widespread area, and difficult treatment, which will bring great losses to fish farmers. [0003] Since the current outbreaks of aquaculture fish in my country mainly exist in domestic fish, namely herring, grass carp, silver carp, bighead carp, carp and crucian carp, the body surface color and texture of the diseased fish are different from those of normal fish. ...

AI Technical Summary

Problems solved by technology

[0005] However, after obtaining the fish body image of the diseased fish, the existing technology cannot quickly and accurately extract the diseased spots on the fish body surface of the diseased fish. Acquisition and extraction still need to be carried out by the operator manually cropping the fish body image of the diseased fish

The operator manually cuts the fish body image of the diseased fish, which reduces the speed and accuracy of lesion extraction on the one hand

On the other hand, the labor intensity of the operator is increased, and because the operator needs to have professional knowledge in computer and image processing, it is not conducive to large-scale promotion in the industry.
