A scale weighted fuzzy c-means clustering algorithm(SWFCM) is proposed for effective segmentation of purple soil color image. The main work is to establish the maximum difference optimization model with the mean of Gaussian distance between each pixel and each peak of the image histogram, and optimize the clustering number and the initial clustering centers. Then, the compactness of each class is defined to weight the Euclidean distance between the pixel and the clustering center and improve the optimization model of FCM for raising its clustering performance. Aiming at the problem of removing scattered small soil blocks in the background and filling holes in the purple soil region, the algorithm of extracting the boundary of the purple soil region and the algorithm of filling the purple soil region are proposed. Finally, the normal and robust experiments are carried out on the normal sample set and robust sample set. And the performances of relative algorithms are compared, which involves the previously released FCM algorithms and some methods for the segmentation of purple soil color image and our proposed algorithm. Experimental results show that performance of SWFCM is better and it can provide a high reference for adaptive segmentation of purple soil color images. Especially for robust experiment images, its average segmentation accuracy is improved by 6\u00a0.\u00a064%\u00a0\u223c\u00a08\u00a0.\u00a025\u00a0% compared with other purple soil segmentation algorithms.<\/jats:p>","DOI":"10.3233\/jifs-202401","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T13:41:18Z","timestamp":1621345278000},"page":"11201-11215","source":"Crossref","is-referenced-by-count":1,"title":["Adaptive
