Aiming at problem that synthetic aperture radar( SAR) image is susceptible to noise
precision of segmentation method is low
a novel SAR image segmentation algorithm based on multilevel threshold of Tsallis entropy in frequency domain guided filtering is proposed. Nonsubsampled contourlet transform( NSCT) is used to decompose the source image into multi-scale to extract high frequency. Information guide filtering is used to enhance edges information of high frequency component and suppress speckle noise while preserving edges. Multithreshold selection algorithm based on improved two-dimension Tsallis entropy is used to make a precise segmentation for enhancement images. Experimental results show that the proposed method is insensitive to noise and effectively improves precision of image segmentation and adaptability.
