Abstract

The invention belongs to the field of computer vision mode recognition and image understanding and relates to an automatic image segmentation method of continuous quantum goose group algorithm evolution pulse coupling neural network system parameters. The method comprises the steps that a minimum combination weighting entropy model of automatic image segmentation of the evolution pulse coupling neural network system parameters is established; a continuous quantum goose group population space is initialized; a simulation quantum rotating door is used for updating the position of each wild goose; the position of each wild goose corresponds to a pulse coupling neural network system parameter, a pulse coupling neural network system is activated for image segmentation, and a fitness value of a new position of an i wild goose is computed; the history optimal quantum positions and the history optimal positions of all wild geese are updated; whether the maximum iteration algebra is reached is checked; and a pulse coupling neural network model is substituted to carry out segmentation on images and output the images after segmentation. The method has the advantages of being small in computing amount, high in convergence rate and high in optimizing capacity.

Description

technical field [0001] The invention belongs to the fields of computer vision pattern recognition and image comprehension, and relates to an automatic image segmentation method for evolving parameters of a pulse-coupled neural network system using a continuous quantum geese swarm algorithm. technical background [0002] Image segmentation refers to the technology and process of dividing an image into regions with different characteristics and extracting objects of interest. Image processing after segmentation, such as feature extraction and target recognition, all depend on the quality of image segmentation, so image segmentation has always been a research hotspot in the field of computer vision and pattern recognition. [0003] Pulse-coupled neural network (PCNN) is derived from the study of the phenomenon of burst-synchronous oscillation of neurons in the cat's visual cortex, and is well suited for image processing due to its biological background. At present, PCNN has be...
