SAR Image Structure Optimization Method Using Sobel Operator Fusion
Aiming at the problem of traditional rolling guided filtering algorithms facing many trivial texture effects and prone to false edges when processing SAR images,this paper proposed a Sobel operator to adaptively calculate the gradient of each pixel in the image to reflect the edge strength of the image to guide the adjustment of rolling guided filtering parameters and optimize the results of rolling guided filtering.The results of edge en-hancement and detail texture extraction in radar image processing using traditional and improved algorithms showed that the proposed Sobel operator for adjusting rolling guided filtering parameters had a significant im-provement,which could effectively support the subsequent processing of radar images and provide a new method for extracting strong scattering bands in images.
