SAR滤波MATLAB程序
孔径雷达图像固有的相干斑噪声严重降低了图像的可解译程度,影响了后续目标检测、分类和识别
等应用。因此,SAR图像的相干斑抑制问题一直是SAR图像应用的重要课题之一。一个理想的去斑算法应该在平
滑的同时保持图像的边缘等细节不受损失,目前存在各种各样的算法,但没有一种方法能够完美的满足这一要求。
本文对SAR图像的相干斑抑制问题进行了全面系统的研究,分析了相干斑的形成原因,总结了目前存在的相干斑
抑制算法的主要思路,介绍了具有代表性的算法,并对各种算法的性能进行了定性分析和比较,给出了去斑算法定
量评估方法(The inherent speckle noise of the aperture radar image seriously reduces the degree of interpretation of the image, and affects the detection, classification and recognition of the subsequent targets.
And other applications. Therefore, the problem of speckle suppression in SAR images has been one of the most important topics in the application of SAR images. An ideal speckle algorithm should be flat
At the same time, the details such as edges of images are not lost. There are various algorithms at present, but none of them can satisfy this requirement perfectly.)

SegmentationforImagesofVCH-F1BasednmprovedWatersed
针对分水岭算法存在的过分割问题以及VCH-F1切片图像的特点,提出一种能够有效消除局部极小值和噪声干扰的自动分割方法。首先比较彩色分量梯度图,选择分量图像的梯度信息,达到有效提取图像边缘信息的目的;然后提出基于多阈值分割的方法消除无效梯度信息;最后介绍了算法的步骤及结果。实验结果证明,通过该方法处理的梯度图像再进行分水岭算法处理,即使不进行区域合并也能达到很好的效果。(Watershed algorithm for over-segmentation problem of the existence of VCH-F1 as well as the characteristics of the image slice, a can effectively eliminate the local minimum value and noise automatic segmentation method. Comparing the first color component gradient map, select the quantity of image gradient information, achieve an effective extraction of image edge information purposes then made based on multi-threshold segmentation method to eliminate invalid gradient information Finally introduce the steps of the algorithm and results. Experimental results show that the adoption of the method of treatment of gradient watershed algorithm for image re-treatment, even if there is no regional merger will also achieve good results.)
