## MATLAB环境下图像区域分割算法设计+程序代码

Abstract Image segmentation is an important technology in digital image processing technology,plays a key role in the image analysis,image recognition and image compression in the image processing fields,in the military,meteorology,transportation and other fields have a wide range of applications.For region segmentation of the image is for deeper understanding and analysis,it is according to the practical application of the target in the image feature extraction and separate the target object and the background,achieve useful information from the images,to improve the quality of image communication to lay the foundation.

This paper studies regional segmentation algorithm in image segmentation.First of all,the paper introduces the commonly used image segmentation algorithm.On this basis,for region segmentation algorithm of region growing and region pided merger were studied.A comparison of two execution modes,and the MATLAB environment of quadtree segmentation algorithm function are analyzed.Finally,in the MATLAB environment of threshold segmentation,edge detection and region growing and region pision merge (guadtree) programming experiment,and the experimental results are compared. Experimental results show that the best effect is the region growing algorithm to extract the image target,quadtree decomposition is suitable for local target extraction,the part contour of the object is neglected, this algorithm needs to improve in the future.
key words： Image segmention   Region growing
Region splitting and merging   Guadtree decomposition
