Problems solved by technology

However, this algorithm lacks a further method to specify the cluster center, and still relies on human intervention, so it cannot achieve adaptive selection of the cluster center
[0005] Therefore, the current technical problems are: how to perform efficient and accurate clustering segmentation without prior knowledge, how to realize the adaptive clustering and segmentation

Abstract

The invention discloses an image segmentation method, system and medium based on image feature density peak search. The method combines a novel clustering algorithm with image features to realize image segmentation. It is mainly divided into the following key parts: image preprocessing, feature value extraction, variable solution and utilization in cluster analysis, and the realization of adaptive selection of cluster centers. First, the original image in units of pixels is roughly divided into color block diagrams in units of superpixels, and cluster analysis is performed by extracting these color blocks as sample points. After the cluster analysis results are obtained, a function is constructed to select the cluster center , and finally return the superpixel sequence to a pixel sequence, and get the final result of clustering according to the index and number. Thus, the cluster-based segmentation is completed.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image segmentation method, system and medium based on image feature density peak search. Background technique [0002] In the environment of information explosion, images, as an important carrier of information transmission, storage and expression, are one of the important means for human beings to obtain information. People hope to extract and utilize information on pictures more efficiently, so image processing technology emerges as the times require. Among them, image segmentation is a key link in image processing and image analysis, and it is also a classic problem. Image segmentation technology is the technology and process of dividing an image into multiple regions with different characteristics and extracting objects of interest, in order to provide a basis for subsequent detailed digital image processing. In order to better identify and process the target in the image...
