基于周边抑制机理的遥感图像背景纹理抑制方法

针对遥感图像中主要目标周围的纹理信息对目标识别造成的干扰，提出了基于周边抑制机理的背景纹理抑制方法。通过在边缘提取的基础上增加周边抑制模块，实现了对纹理边缘和轮廓边缘的分别处理，有效地抑制了纹理、保留了轮廓。以周边抑制机理为基础，结合多尺度处理技术，进一步提高了背景纹理抑制的效果。实验结果表明，本方法可以有效抑制背景纹理，为识别有较多背景纹理的遥感图像地物目标创造良好条件。

Background Texture Suppression Method in Remote Sensing Images Based on Surround Suppression Mechanism

Against the disturbance of object recognition caused by texture information around major objects, a method for background texture suppression based on surround suppression mechanism is proposed. By adding surround suppression module to edge extraction, texture edges and contour edges are processed respectively, and therefore textures are effectively suppressed while contours are mostly retained. Based on surround suppression mechanism and combined with multi-scale processing technology, the background texture suppression effects are further enhanced. Experimental results demonstrate that the proposed method can effectively suppress background texture and thereby provide favorable conditions for recognizing ground objects in remote sensing image with considerable background texture.
