The embodiments of the invention disclose a
grayscale image recognition method, a
grayscale image recognition device, a
grayscale image recognition apparatus and a readable storage medium. The methodincludes the following steps that: the
network model of the extracted outline pixel points of a grayscale image to be identified is established based on a
complex network method and a
watershed algorithm;
distance threshold values in a
distance threshold value set are applied to the node set of the initial
network model, corresponding sub-network models are established; the topological parametersof the sub-network models are calculated, so as to form the target recognition parameters of the grayscale image to be identified; the strength of each node in the initial
network model is calculated,nodes of which the strength satisfies a preset strength condition are selected from the nodes according to the strength of the nodes, so as to form a target network interest
point set; and a candidate
sample image which satisfies a preset parameter condition and has the same network interest point can be obtained from a sample
library by means of matching according to the target recognition parameters and the target network interest
point set, and the category of the candidate
sample image is the category of the grayscale image to be identified. With the grayscale image recognition method, device, apparatus and readable storage medium of the invention adopted, the recognition efficiency of grayscale images can be improved.
