A multi-target fast fuzzy clustering color image segmentation method based on semi-supervised learning and histogram statistics

Abstract

The invention discloses a multi-target fast fuzzy clustering color image segmentation method based on semi-supervised learning and histogram statistics. The method comprises the following steps: inputting a color image to be segmented; Setting an initial population number of the color image, the Maximum number of iterations, and the Maximum clustering number, obtaining paired constraint information given by a user and processing the paired constraint information to obtain paired constraint matrixes; obtaining a color histogram according to the color image; based on the Color histogram, constructing a fitness function of intra-class compactness based on paired constraint and inter-class separability based on clustering inpurity; secondly, designing self-adjusting crossover and variation rate, utilizing mixed crossover and non-uniform variation to generate filial generations so as to ensure the diversity of the filial generations, finally constructing clustering non-purity effectivenessindexes based on color histograms, selecting an optimal solution from an optimal solution set, and obtaining a final segmentation result. According to the method, under the condition that a small amount of paired constraint information is used, rapid segmentation can be achieved, and the segmentation number and the good segmentation effect are obtained in a self-adaptive mode.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a multi-objective fast fuzzy clustering color image segmentation method based on semi-supervised learning and histogram statistics. Background technique [0002] Image segmentation is an important part of the image processing process. It divides the image into several different regions. The features in the same region are consistent, which is helpful for the extraction of objects of interest. The quality of image segmentation directly affects the follow-up process of image processing, so people pay more and more attention to it. In recent years, as the computer's ability to process data has been greatly improved, the research on color image segmentation technology has attracted the attention and attention of scholars at home and abroad. At present, we can divide color image segmentation algorithms into threshold-based, edge-based, region-based and cluster-based segmenta...
